The Connection Between Forage and Equine Ulcers

Equine gastric ulcers can affect horses of many ages, breeds, and activity levels. They are especially familiar to owners of performance horses, frequent travelers, and animals exposed to significant changes in routine, but they are not limited to those groups.

Ulcers can also occur in pleasure horses, senior horses, breeding animals, and horses living seemingly quiet lives.

Because feeding practices influence the environment within the horses stomach, forage management is an important part of supporting gastric health. However, hay should never be viewed as a cure for ulcers. Horses showing signs of gastric discomfort need veterinary evaluation, and confirmed ulcers may require medical treatment in addition to management changes.

Understanding Equine Gastric Ulcers

Equine gastric ulcer syndrome is a broad term used to describe ulceration affecting the lining of the horses stomach.

The condition may be difficult to recognize because many affected horses show only subtle or inconsistent signs. Possible signs can include:

● reduced appetite

● weight loss

● declining body condition

● changes in attitude

● decreased performance

● reluctance to train

● sensitivity around the girth

● dull coat

● mild or recurring colic

These signs are not specific to ulcers and may also occur with other medical or management problems. Gastroscopy, in which a veterinarian examines the stomach with an endoscope, is the definitive way to identify gastric ulceration.

The Horses Stomach Is Designed for Frequent Eating

Horses evolved to consume small amounts of forage over much of the day.

Their stomachs continuously produce acid, including during periods when they are not eating. Under natural grazing conditions, frequent forage intake helps moderate that environment because feed and saliva provide buffering within the stomach.

Modern management can create a very different feeding pattern.

A horse may receive hay only a few times per day, finish it quickly, and then remain without forage for several hours. During these empty periods, acid continues to be produced even though less feed and saliva are present to help buffer it.

This does not mean every horse with scheduled meals will develop ulcers. It does mean that long periods without forage may be an important consideration when managing horses at risk.

Chewing Forage Encourages Saliva Production

Unlike people, horses produce most of their saliva while chewing.

Long-stem forage requires substantial chewing, which encourages saliva flow. Saliva helps moisten feed and provides natural buffering as it enters the stomach.

This is one reason forage supports gastric health differently from a small, rapidly consumed concentrate meal.

Hay that is palatable and comfortable to chew may help encourage:

● longer eating periods

● greater saliva production

● steadier forage intake

● more natural feeding behavior

The benefit comes not from one particular hay species, but from providing appropriate forage that the horse consistently eats.

Avoid Unnecessarily Long Gaps Without Forage

One of the most practical management goals for an ulcer-prone horse is reducing extended fasting periods whenever the horses health and calorie requirements allow it.

Possible strategies include:

● dividing hay into more frequent feedings

● using an appropriately designed slow feeder

● providing turnout with safe pasture access

● placing hay at several feeding stations

● offering a late-evening feeding

● checking how quickly the horse actually finishes each portion

Slow feeders can be useful, but they should extend eating time rather than make forage so difficult to obtain that the horse becomes frustrated or consumes too little.

Easy keepers and horses with metabolic concerns may still require controlled calorie intake. For these animals, the objective is not necessarily unlimited hay. It is to distribute an appropriate daily forage allowance in a way that reduces long empty periods while supporting healthy body condition.

Forage Quality Influences Actual Intake

Providing hay does not help if the horse refuses much of it.

Coarse, dusty, moldy, weather-damaged, or unpalatable forage may lead to:

● selective eating

● reduced total intake

● excessive waste

● longer periods with an empty stomach

Clean, aromatic, appropriately mature hay generally encourages more reliable consumption.

Soft, leafy orchardgrass is often useful in these programs because many horses eat it readily and spend less time sorting through coarse stems. That does not mean orchardgrass treats or prevents ulcers. Its practical value is that palatable forage can support more consistent eating and chewing.

Timothy, smooth bromegrass, bermudagrass, prairie grass, and other well-made grass hays may also be appropriate depending on the individual horse, available hay lot, body condition, and nutritional needs.

Grain May Need to Be Evaluated

Concentrates have an important role in many feeding programs, particularly for horses with high calorie demands. However, large grain meals and feeding programs that provide relatively little forage may contribute to an unfavorable gastric environment.

Owners do not necessarily need to eliminate grain. Instead, they may need to consider:

● whether the horse truly requires the current amount

● whether large meals can be divided into smaller portions

● whether more calories can come from digestible fiber

● whether forage is available before concentrates are fed

● whether the horse is receiving enough total roughage

Any significant dietary adjustment should be made gradually, especially in horses already experiencing digestive discomfort.

Alfalfa May Have a Place in Some Programs

Alfalfa is sometimes incorporated into feeding programs for horses with gastric concerns because its nutritional composition may provide greater buffering than some grass hays.

A modest amount of alfalfa, or an orchardgrass/alfalfa blend, may be appropriate for certain horses - particularly those that also need additional calories, protein, or highly palatable forage. Some veterinary management plans also use a small forage meal before strenuous exercise.

Alfalfa is not automatically appropriate for every horse. Easy keepers, horses with particular mineral requirements, and animals needing tightly controlled calorie intake may require a different approach.

The decision should reflect the entire feeding program rather than the belief that one forage species can solve a medical condition.

Exercise and Travel Affect Gastric Management

Performance horses frequently experience several ulcer risk factors at the same time:

● intense exercise

● transportation

● stall confinement

● schedule changes

● unfamiliar environments

● reduced turnout

● interrupted feeding routines

During exercise, acidic stomach contents may reach the more vulnerable upper portion of the stomach. Transport, confinement, and changes in routine may add further stress.

For horses that travel regularly, owners can support feeding consistency by:

● bringing familiar hay when practical

● offering forage during safe travel stops

● avoiding abrupt hay changes at events

● encouraging hydration

● maintaining familiar feeding times

● discussing preventive medical management with a veterinarian

A horse that eats well at home may consume far less forage in an unfamiliar stall, so actual intake deserves close attention.

Stress Management Is Part of the Feeding Program

Nutrition is only one part of gastric health.

Herd conflict, isolation, frequent travel, heavy training, pain, illness, and prolonged confinement may all affect appetite and stress levels.

Management changes that may help include:

● increasing turnout where appropriate

● allowing safe social contact

● maintaining predictable routines

● reducing unnecessary training intensity during treatment

● providing multiple feeding areas for group-housed horses

● preventing dominant animals from guarding forage

A well-designed feeding program cannot fully compensate for an environment that repeatedly prevents a horse from eating comfortably.

Medical Treatment and Forage Management Work Together

When gastric ulcers are suspected, simply changing hay is not an adequate substitute for veterinary care.

A veterinarian may recommend gastroscopy, medication, changes in exercise, or modifications to the horse's feeding and turnout routine. Management changes are important because ulcers may recur when the same risk factors remain after treatment.

Forage management should be viewed as one part of a broader plan that may also

include:

● veterinary diagnosis

● prescribed medication

● stress reduction

● exercise modification

● concentrate evaluation

● consistent access to clean water

● careful monitoring of appetite and body condition

The strongest programs address both the medical condition and the daily routine surrounding it.

Choosing Hay at the Barn

When selecting hay for a horse with a history of gastric discomfort, begin with the question that matters most: Will this horse eat it consistently?

Look for forage that is:

● clean and properly cured

● free from visible mold

● low in dust

● pleasantly aromatic

● comfortable to chew

● consistent from bale to bale

Soft orchardgrass may be an excellent option for a selective eater, while an orchardgrass/alfalfa blend may suit a horse needing more nutritional density. A moderate grass hay may be more appropriate for an easy keeper whose daily intake must be carefully managed.

The species name matters, but it is only one part of the decision. Harvest maturity, leaf retention, cleanliness, storage, palatability, and the horses individual requirements all influence whether a particular hay will fit the feeding program.

FAQ

Can hay cure gastric ulcers in horses?

No. Appropriate forage management may support gastric health and reduce certain risk factors, but it does not replace veterinary diagnosis or prescribed ulcer treatment.

What hay is best for a horse prone to ulcers?

There is no single best hay for every horse. Clean, palatable forage that encourages frequent chewing and consistent intake is generally valuable. Soft orchardgrass is often well accepted, while some horses may benefit from a modest amount of alfalfa or an orchardgrass/alfalfa blend.

Should ulcer-prone horses have hay available all the time?

Frequent forage access is often helpful, but the feeding plan must also account for body condition, metabolic health, and total calorie intake. Controlled portions can be divided across the day to reduce long gaps without forage.

Can large grain meals contribute to gastric problems?

High-concentrate feeding and relatively low forage intake may contribute to an unfavorable gastric environment in some horses. Concentrates may still be necessary, but large meals can often be divided and balanced with adequate forage.

How can I tell whether my horse has ulcers?

Possible signs include appetite changes, weight loss, poor performance, girth sensitivity, attitude changes, and recurring mild colic. These signs are nonspecific, and gastroscopy is the definitive diagnostic method.

Feeding Hard Keepers Without Excess Grain

When a horse begins losing weight or struggles to maintain body condition, one of the first instincts is often to increase grain. While concentrates can certainly play an important role for some horses, they are not always the best place to begin.

A horses digestive system is designed to utilize forage as its primary source of nutrition.

In many cases, improving forage quality, increasing digestible fiber intake, and encouraging more consistent hay consumption can provide a stronger foundation for healthy weight gain than simply feeding larger grain meals.

For horses that have difficulty maintaining condition, a forage-first approach often supports digestive health while supplying the calories needed for gradual, sustainable improvement.

Understanding the Hard Keeper

The term “hard keeper” describes a horse that requires more nutritional support than expected to maintain an appropriate body condition.

Several factors may contribute, including:

● naturally fast metabolism

● high activity level

● advancing age

● stress

● dental problems

● recovery from illness or injury

● environmental conditions

● increased calorie demands

Every hard keeper has a different story.

Rather than searching for one universal feeding solution, owners should focus on identifying the factors affecting that individual horse.

Why More Grain Isn’t Always the Answer

Grain provides concentrated calories, but horses are not designed to consume large amounts of starch in a single meal.

Overfeeding concentrates may increase the risk of digestive disturbances in some horses while doing little to address the underlying issue if forage intake remains inadequate.

Instead of asking, “How much grain should I feed?”

It is often more helpful to ask:

● Is my horse eating enough hay?

● Is the hay digestible?

● Is the horse wasting forage?

● Is the forage consistent from day to day?

These questions frequently lead to more sustainable improvements.

Maximize Forage Before Adding Concentrates

Because horses naturally spend much of the day consuming forage, increasing the quality of hay often produces better long-term results than increasing concentrates alone.

Many owners focus on providing forage that is:

● clean

● leafy

● highly digestible

● dust-free

● consistent

Premium orchardgrass is commonly selected for hard keepers because many horses find it soft, appealing, and easy to consume. A horse that enthusiastically finishes every flake often receives more usable nutrition than one picking through coarse, stemmy hay.

For horses requiring additional calories, an orchardgrass/alfalfa blend may also be appropriate within a balanced feeding program, depending on the horses individual nutritional needs.

Digestibility Creates Usable Calories

Not every calorie contained in hay is equally available to the horse.

Digestibility influences how efficiently nutrients can be extracted during fermentation in the hindgut.

Hay harvested at the appropriate stage of maturity often provides:

● greater leaf retention

● finer stems

● improved digestibility

● increased palatability

This combination may help horses maintain body condition without dramatically increasing the volume of feed offered.

Feeding more poor-quality forage rarely produces the same results as feeding appropriate amounts of highly digestible forage.

Encourage Steady Forage Intake

A horse that spends many hours each day consuming hay more closely follows its natural feeding behavior.

Whenever practical, owners may benefit from encouraging consistent forage availability rather than relying on a few large meals.

Steady forage intake supports:

● healthy hindgut fermentation

● regular chewing activity

● saliva production

● digestive comfort

● more consistent calorie intake

Some hard keepers perform well with nearly continuous access to appropriate forage, although feeding strategies should always reflect the individual horses health and management requirements.

Small Changes Add Up

Weight gain usually occurs gradually.

Rather than making several major feeding changes simultaneously, many owners achieve better results through small adjustments such as:

● improving forage quality

● increasing feeding frequency

● reducing unnecessary hay waste

● monitoring body condition regularly

● maintaining consistent feeding schedules

These incremental improvements make it easier to evaluate which changes are truly benefiting the horse.

Don’t Overlook Hay Waste

One of the most overlooked reasons horses fail to gain weight is simple forage waste.

A horse that leaves twenty percent of every feeding behind receives significantly fewer calories than expected.

Waste often increases when hay is:

● overly coarse

● excessively stemmy

● dusty

● weather damaged

● inconsistent in texture

Selecting forage that horses willingly consume may improve intake without increasing the amount fed.

Good feeder design can also help reduce losses from trampling or contamination.

Body Condition Is More Important Than the Feed Tag

Feeding recommendations printed on feed bags provide useful starting points, but they cannot account for every horses metabolism or management conditions.

Owners should routinely evaluate:

● ribs

● topline

● neck

● shoulders

● hips

● overall muscling

Photographs taken every few weeks can help identify gradual improvements that might otherwise go unnoticed.

Healthy body condition remains a better measure of feeding success than the number of pounds of grain being fed.

Work With the Whole Feeding Program

Nutrition rarely exists in isolation.

Exercise, dental health, parasite control, stress, shelter, and access to clean water all influence how effectively a horse maintains weight.

Forage should work together with the rest of the management program rather than being viewed as only one component of it.

When the overall program supports the horses health, nutritional improvements are often easier to achieve and maintain.

Choosing Hay at the Barn

Experienced forage growers know that the highest-quality hay is not necessarily the richest hay.

For a hard keeper, the goal is to find forage that the horse eagerly eats, comfortably chews, and efficiently digests. That usually means looking beyond species alone and evaluating softness, leafiness, aroma, cleanliness, and consistency.

Ask your hay supplier about harvest maturity, storage conditions, and which lots are particularly well suited for horses needing additional condition. Those conversations often provide information that cannot be seen simply by looking at the outside of a bale.

FAQ

Can a hard keeper gain weight without feeding large amounts of grain?

Many horses can improve body condition by maximizing forage quality, digestibility, and intake before substantially increasing grain. Every horses nutritional requirements are different.

What type of hay is often recommended for hard keepers?

Many owners choose highly palatable, digestible grass hay. Premium orchardgrass is frequently selected because many horses consume it readily, while orchardgrass/alfalfa blends may provide additional calories for horses with higher nutritional demands.

Why is digestible fiber important?

Digestible fiber provides a major source of energy through hindgut fermentation while supporting healthy digestive function and natural feeding behavior.

Should I simply feed more hay if my horse is thin?

Quantity certainly matters, but quality matters just as much. Feeding digestible, well-made forage that the horse consistently eats often produces better results than simply increasing the amount of poor-quality hay.

Choosing Softer Hay for Senior Horses

Advances in veterinary care, nutrition, and management have allowed horses to live longer than ever before. Many horses remain active well into their twenties and even thirties, but aging often brings new nutritional challenges that require adjustments to the feeding program.

One of the most important changes involves forage.

Senior horses continue to rely on hay as the foundation of their diet, yet they may no longer be able to chew or digest forage as efficiently as they once did. Choosing softer, highly palatable hay can help older horses maintain healthy body condition while supporting the digestive system that has served them throughout a lifetime.

Fortunately, small adjustments in forage selection often make a meaningful difference in both comfort and long-term health.

Aging Changes How Horses Eat

A horses digestive system remains remarkably efficient throughout life, but normal aging affects several aspects of feeding.

Older horses may experience:

● worn or missing teeth

● reduced chewing efficiency

● slower eating

● decreased muscle mass

● changing calorie requirements

● reduced ability to utilize nutrients

Many senior horses continue eating enthusiastically, yet quietly consume less forage than owners realize because chewing has become more difficult.

Weight loss may develop gradually over several months before becoming obvious.

Softer Hay Makes Chewing Easier

Chewing is the first - and one of the most important - steps in digestion.

When horses cannot adequately grind forage, they often swallow longer pieces of plant material that are more difficult to digest efficiently.

Softer hay may help by providing:

● finer stems

● greater leaf content

● improved chewability

● increased comfort during eating

● better overall intake

Many horse owners notice that senior horses spend less time sorting through softer hay and more time actually consuming it.

That improved intake can have a positive effect on maintaining body condition.

Palatability Encourages Consistent Eating

As horses age, appetite sometimes becomes more selective.

Older horses may ignore hay that is:

● coarse

● stemmy

● dusty

● weathered

● inconsistent from bale to bale

Conversely, clean, leafy forage with a pleasant aroma often encourages more consistent consumption.

Premium orchardgrass is frequently appreciated for its soft texture and natural palatability. Many senior horses readily accept it, making it a dependable option for encouraging steady forage intake.

The goal is not simply offering more hay - it is offering hay the horse wants to eat.

Digestibility Becomes Increasingly Important

A horse that eats the same amount of forage at twenty-five years of age may not extract nutrients as efficiently as it did at ten.

Digestible forage helps older horses obtain more nutritional value from each mouthful.

Characteristics that often support digestibility include:

● abundant leaves

● appropriate harvest maturity

● proper curing

● minimal weather damage

● careful storage

These qualities are usually more important than choosing a particular species alone.

Well-managed orchardgrass, orchardgrass/alfalfa blends, smooth bromegrass, timothy, or other premium grass hays may all have a place depending on the individual horses nutritional requirements.

Dental Care and Hay Selection Work Together

Selecting softer forage does not replace regular dental care.

Routine dental examinations remain one of the most valuable investments owners can make for senior horses.

Signs that suggest chewing has become difficult include:

● quidding (dropping partially chewed hay)

● eating more slowly than herd mates

● excessive hay left in the feeder

● long forage fibers in manure

● gradual weight loss

● reluctance to finish meals

When these signs appear, adjusting both dental care and forage selection often provides better results than focusing on either one alone.

Don’t Confuse Softness with Poor Fiber

Some owners worry that softer hay contains less fiber.

In reality, quality soft hay still provides the long-stem fiber horses require for healthy digestion.

The difference is that premium soft hay often contains:

● finer stems

● greater leaf retention

● more comfortable chewing texture

● improved digestibility

Older horses still benefit from long-stem forage because chewing stimulates saliva production and supports the healthy microbial population within the hindgut.

Soft does not mean nutritionally incomplete.

Monitor Body Condition Throughout the Year

Seasonal changes often affect senior horses more noticeably than younger animals.

Cold weather increases calorie requirements, while hot weather may reduce appetite.

Regular monitoring helps owners recognize small changes before they become serious.

Useful observations include:

● body condition score

● topline muscle

● appetite

● hay waste

● manure consistency

● coat quality

● overall attitude

Small nutritional adjustments made early are usually easier than correcting significant weight loss later.

Hay Quality Matters Every Day

Consistency becomes increasingly valuable as horses age.

Frequent changes in forage can make it more difficult to evaluate whether nutritional adjustments are working.

Reliable hay quality allows owners to monitor:

● body condition

● appetite

● digestive comfort

● manure quality

● feeding behavior

A consistent source of premium forage also reduces unnecessary stress for horses that thrive on routine.

Every Senior Horse Is Different

Not every older horse requires exactly the same feeding program.

Some maintain excellent weight on moderate grass hay well into their later years.

Others benefit from:

● softer forage

● greater digestibility

● additional calories

● soaked hay

● chopped forage

● specialized feeds

Age alone should never determine the diet.

Instead, feeding decisions should reflect the horses body condition, dental health, activity level, metabolism, and overall quality of life.

The objective is helping each horse remain comfortable, healthy, and able to enjoy eating for as many years as possible.

Choosing Hay at the Barn

One of the first things experienced horse owners often do when shopping for a senior horse is reach into the bale.

They feel the stems.

They look for leafy growth.

They smell the hay.

Those simple observations reveal far more than color alone.

Premium hay for senior horses should feel inviting to both the horse and the owner.

Softness, cleanliness, pleasant aroma, and consistency from bale to bale often tell the story of careful harvest timing and proper storage. When selecting forage for an older horse, choosing hay that encourages enthusiastic eating is every bit as important as meeting nutritional requirements.

FAQ

What type of hay is often best for senior horses?

Many senior horses do well on soft, leafy, highly digestible forage. Premium orchardgrass is a popular choice because many older horses find it comfortable to chew, while some horses may benefit from orchardgrass/alfalfa blends or other premium hays depending on their individual nutritional needs.

Why do older horses waste more hay?

Dental wear, missing teeth, and reduced chewing efficiency may make it difficult for senior horses to fully consume coarse or stemmy forage.

Does a senior horse always need a different type of hay?

Not necessarily. Some older horses continue thriving on the same forage for many years. The need for change depends on body condition, dental health, appetite, and overall nutritional requirements.

Can softer hay help an older horse maintain weight?

In many cases, yes. Softer, more digestible forage may encourage greater intake and allow senior horses to utilize nutrients more efficiently, particularly when chewing has become more difficult.

The Role of Digestible Fiber in Horse Nutrition

Horse owners often hear about protein, fat, sugar, vitamins, and supplements, but one nutrient quietly supports nearly every aspect of a horses health: fiber.

Unlike many other animals, horses are designed to obtain much of their energy from the fermentation of plant fiber. While concentrates and supplements may have a place in some feeding programs, forage remains the nutritional foundation for virtually every horse, regardless of age, breed, or activity level.

Understanding the difference between simply feeding fiber and providing digestible fiber can help owners make better decisions about hay selection and long-term feeding management.

Horses Are Natural Forage Eaters

The horses digestive system evolved to process forage almost continuously.

Under natural conditions, horses spend many hours each day grazing, consuming small amounts of fiber over an extended period. This steady intake supports both digestive function and normal behavior.

Long-stem forage helps promote:

● continuous chewing

● saliva production

● healthy hindgut fermentation

● normal intestinal movement

● natural feeding behavior

When forage forms the foundation of the diet, the digestive system generally functions more efficiently than when horses rely heavily on large concentrate meals.

What Is Digestible Fiber?

Not all fiber is equally useful.

Digestible fiber refers to the portion of plant material that the microorganisms in the horses hindgut can break down and convert into usable energy.

This process produces volatile fatty acids, which provide a significant source of calories for the horse while supporting normal digestive function.

Several factors influence fiber digestibility, including:

● forage species

● stage of maturity

● leaf-to-stem ratio

● growing conditions

● harvest timing

● curing practices

● storage conditions

Because of these variables, two bales of hay harvested from different fields - or even different cuttings of the same field - may provide noticeably different nutritional value.

The Hindgut Does Most of the Work

Unlike cattle, horses do not digest fiber efficiently in the stomach.

Instead, most fiber fermentation occurs in the cecum and large colon, where billions of beneficial microorganisms break down plant material.

These microbes depend on a relatively stable environment.

Abrupt dietary changes, inconsistent feeding schedules, or long periods without forage may disrupt this delicate microbial balance.

Maintaining a consistent forage program helps support the healthy microbial population that allows horses to utilize fiber effectively.

Digestibility Matters More Than Appearance

Bright green color often attracts buyers, but appearance tells only part of the story.

Hay that looks beautiful from a distance may not always provide the level of digestibility a particular horse needs.

Likewise, hay that appears slightly less vibrant may still offer excellent nutritional value.

When evaluating forage, experienced horse owners often consider:

● softness

● leafiness

● stem thickness

● aroma

● cleanliness

● overall consistency

These characteristics frequently provide a better indication of feeding value than color alone.

Different Horses Need Different Levels of Digestibility

Highly digestible forage is not automatically the best choice for every horse.

Instead, digestibility should match the animals nutritional requirements.

For example:

● senior horses often benefit from softer, highly digestible forage

● hard keepers may require forage that supplies additional usable energy

● performance horses frequently have increased calorie demands

● easy keepers may do well on moderately digestible forage that supports weight management while still providing adequate fiber

Matching hay to the individual horse helps create a more balanced feeding program than relying on species alone.

Forage Species Are Only Part of the Picture

Horse owners sometimes ask whether one species of hay is inherently more digestible than another.

The answer is rarely that simple.

Harvest timing and plant maturity often influence digestibility as much as the species itself.

Properly harvested orchardgrass is widely appreciated for its combination of:

● soft texture

● good leaf retention

● consistent palatability

● excellent digestible fiber

Well-made timothy, smooth bromegrass, bermudagrass, and prairie grass can also provide valuable sources of fiber when matched appropriately to an individual horses needs.

The goal is selecting clean, properly cured forage that fits the horse rather than searching for one universally “best” hay.

Fiber Supports More Than Digestion

Owners sometimes think of fiber simply as roughage.

In reality, digestible fiber contributes to many aspects of a horses health, including:

● maintaining body condition

● supporting normal gut function

● encouraging healthy chewing behavior

● promoting saliva production

● helping satisfy the horses natural desire to forage

Adequate forage intake may also help reduce boredom and support more relaxed feeding behavior because horses are naturally adapted to spend much of the day eating.

Consistency Helps the Digestive System Adapt

The microorganisms responsible for digesting fiber adapt gradually to changes in forage.

Switching suddenly between different hay types, maturity levels, or feeding schedules may make that adjustment more difficult.

Whenever possible, owners should:

● introduce new hay gradually

● maintain regular feeding times

● avoid unnecessary changes

● monitor appetite and manure quality

● observe body condition over time

A predictable feeding program often supports both digestive health and easier nutritional management.

Hay Testing Provides Additional Insight

Visual inspection can reveal many important characteristics, but it cannot measure digestibility.

Laboratory forage analysis provides information that the eye cannot, including:

● fiber levels

● protein

● moisture

● energy values

● mineral content

● non-structural carbohydrates (NSC)

For horses with specific nutritional needs, forage testing can help owners make more informed decisions and reduce guesswork.

Building Nutrition on a Strong Foundation

The healthiest feeding programs rarely begin with supplements.

They begin with selecting forage that meets the horses nutritional requirements and encouraging consistent daily intake.

Digestible fiber remains the foundation upon which the rest of the diet is built.

When owners prioritize forage quality, consistency, and appropriate digestibility, they often find that many other aspects of nutritional management become easier as well.

Choosing Hay at the Barn

A good hay supplier looks beyond the name of the species and pays close attention to how the forage was produced. Two loads of orchardgrass harvested a few weeks apart may differ in softness, maturity, and digestibility because weather and growing conditions are never exactly the same.

When choosing hay, don’t hesitate to ask questions about harvest timing, storage, and intended use. A supplier who understands the forage they are selling can often help match available hay to your horses age, activity level, and body condition rather than simply recommending the same product for every customer.

FAQ

Why is fiber so important for horses?

Fiber provides the foundation of the equine diet. It supports healthy digestion, hindgut fermentation, normal chewing behavior, and supplies a significant portion of a horses daily energy needs.

What is digestible fiber?

Digestible fiber is the portion of plant material that beneficial microorganisms in the hindgut can break down into usable energy.

Is softer hay always more digestible?

Often, but not always. Plant maturity, harvest conditions, and forage species all influence digestibility. A well-made hay should be evaluated by its overall quality rather than a single characteristic.

Can forage quality affect body condition?

Yes. Horses that consume clean, digestible, highly palatable forage often utilize nutrients more efficiently than horses eating poor-quality or overly mature hay, although each horses nutritional needs should be evaluated individually.

Why Some Horses Struggle to Maintain Weight

Some horses seem to maintain an ideal body condition with very little effort, while others require careful management simply to keep weight on. Owners of these hard keeper horses often find themselves adding supplements, increasing grain, or changing feeding programs in search of a solution.

While there is rarely a single reason a horse struggles to maintain weight, understanding the factors involved can help owners develop a more effective nutritional plan. In many cases, the answer begins with consistent, high-quality forage rather than dramatic changes to the rest of the diet.

A thoughtful feeding program focuses not only on providing enough calories but also on ensuring the horse can comfortably consume, digest, and utilize those calories throughout the year.

Every Horse Has a Different Metabolism

Just as people have different metabolic rates, horses do as well.

Some naturally require more calories to maintain healthy body condition because of:

● genetics

● breed characteristics

● age

● temperament

● activity level

● muscle mass

● environmental conditions

A nervous horse that spends much of the day pacing or constantly moving around the pasture may burn significantly more energy than a quieter companion living under the same conditions.

Understanding an individual horses metabolism helps owners set realistic expectations rather than comparing one horse to another.

Calories Lost Are Calories That Can’t Build Condition

Maintaining weight is a balance between calories consumed and calories used.

A horse may struggle to maintain condition if calories are being diverted toward:

● heavy work

● cold weather

● growth

● lactation

● healing after illness or injury

● chronic stress

Even horses receiving what appears to be an adequate ration may gradually lose weight if their energy demands increase without corresponding nutritional adjustments.

Seasonal changes often play a role as well. During colder months, horses may require additional energy simply to maintain normal body temperature.

Forage Quality Can Make a Significant Difference

Owners sometimes assume that all grass hay provides roughly the same nutritional value.

In reality, forage can vary considerably depending on:

● species

● maturity at harvest

● leaf-to-stem ratio

● weather during curing

● storage conditions

● harvest management

Two bales that look similar from a distance may provide very different levels of digestible energy.

For horses that struggle to maintain weight, premium forage with good digestibility often supports better long-term results than simply increasing the amount of lower-quality hay.

Horses Must Want to Eat Their Hay

One of the simplest reasons some horses fail to gain or maintain weight is that they never consume enough forage.

Hay that is coarse, overly mature, dusty, or inconsistent may lead horses to sort through their feed, leaving behind many of the stems. Even small amounts of waste every day can significantly reduce total calorie intake over time.

Many owners find that soft, leafy orchardgrass encourages more consistent consumption because it is often highly palatable and comfortable to chew. Horses that eagerly clean up their hay generally receive more nutritional value than those that spend hours picking through less appealing forage.

Rather than forcing intake, selecting hay the horse enjoys eating often produces better results.

Dental Health Deserves Regular Attention

Chewing is the first step of digestion.

As horses age, worn or damaged teeth may reduce their ability to grind forage effectively.

Even younger horses occasionally develop dental issues that interfere with normal eating.

Warning signs include:

● slow eating

● quidding (dropping partially chewed hay)

● excessive hay waste

● weight loss

● foul breath

● long forage fibers in manure

Routine dental examinations help identify problems before they significantly affect body condition.

Digestive Health Supports Weight Maintenance

Healthy digestion allows horses to make the most of every bite they consume.

Abrupt changes in forage, inconsistent feeding schedules, or poor-quality hay may interfere with digestive comfort in some horses.

Maintaining a consistent forage program supports:

● healthy hindgut fermentation

● regular fiber intake

● predictable eating habits

● stable body condition

When forage changes become necessary, introducing new hay gradually generally allows the digestive system more time to adapt.

Stress Can Influence Appetite

Stress affects more than behavior.

Travel, competition schedules, herd hierarchy, environmental changes, or recovery from illness may reduce a horses interest in eating.

Some horses continue to nibble throughout stressful periods, while others noticeably reduce their forage intake.

Providing familiar, consistent hay can help encourage more reliable eating during times of change.

Although every situation is different, minimizing unnecessary feeding disruptions often benefits horses that already struggle to maintain condition.

Don’t Chase Quick Fixes

When a horse loses weight, it can be tempting to make several changes at once.

Owners may simultaneously:

● increase grain

● add supplements

● switch hay

● change feeding schedules

● introduce new products

Unfortunately, making multiple changes together often makes it difficult to determine what is actually helping.

Gradual adjustments, combined with careful observation, usually provide a clearer picture of how the horse responds.

Consistency often produces better long-term outcomes than frequent experimentation.

Evaluate Body Condition Regularly

Weight loss usually occurs gradually.

By the time ribs become obvious, a horse may have been losing condition for weeks or even months.

Regular evaluation helps owners identify small changes before they become significant.

Useful observations include:

● body condition score

● topline development

● neck and shoulder muscling

● appetite

● manure consistency

● overall attitude

Taking photographs from the same angle every few weeks can make subtle

improvements - or declines - much easier to recognize.

Nutrition Should Match the Individual Horse

There is no universal feeding program that works for every hard keeper.

Some horses require:

● softer forage

● greater digestibility

● higher calorie density

● increased feeding frequency

● management of underlying medical conditions

Others simply benefit from cleaner, more consistent forage that they enjoy eating every day.

The goal is not to feed the largest amount of hay possible. The goal is to provide forage that the individual horse can consume comfortably, digest efficiently, and utilize effectively over time.

Choosing Hay at the Barn

When selecting hay for a horse that has difficulty maintaining weight, don’t rely solely on color or species. Pick up a flake and look closely. Does it contain abundant leaves? Are the stems fine and flexible rather than coarse and brittle? Does it have a clean, fresh aroma?

Experienced hay producers know that digestibility and consistency are often just as important as appearance. Premium hay is the result of careful harvesting, curing, storage, and handling - not simply the name of the forage species on the label.

Choosing a hay that your horse consistently eats well is often one of the simplest ways to support long-term body condition.

FAQ

Why does my horse stay thin even though it eats plenty of hay?

Several factors may contribute, including forage quality, dental health, workload, metabolism, digestive efficiency, or an underlying medical condition. A veterinarian can help evaluate unexplained weight loss.

What kind of hay is often recommended for hard keepers?

Many owners choose soft, leafy, digestible grass hay that encourages consistent intake. Premium orchardgrass is a common choice, while some horses may benefit from orchardgrass/alfalfa blends depending on their nutritional requirements.

Does cold weather affect a horses weight?

Yes. Horses often use additional energy to maintain body temperature during colder weather, increasing their calorie needs.

Should I change everything if my horse starts losing weight?

Usually not. Making gradual adjustments while monitoring the horse's response often provides clearer information than changing multiple aspects of the feeding program at once.

Helping Underweight Horses Gain Condition Safely

A horse that struggles to maintain weight often causes just as much concern as one that gains weight too easily. Visible ribs, a fading topline, or declining muscle condition naturally lead owners to wonder whether they should simply feed more grain. While concentrates certainly have their place, one of the most effective places to begin is with the foundation of every horses diet: high-quality forage. Helping an underweight horse regain condition is rarely about finding a quick fix.

Instead, success usually comes from identifying the underlying reason for the weight loss while building a consistent feeding program centered around clean, digestible hay that encourages steady forage intake.

Whether the horse is recovering from illness, entering its senior years, competing regularly, or simply has a naturally faster metabolism, thoughtful forage selection can provide the foundation for healthy, sustainable weight gain.

Start by Understanding Why the Horse Is Underweight

Before making significant changes to any feeding program, it is important to consider why the horse has lost condition.

Common causes include:

● advanced age

● increased workload

● dental problems

● parasites

● illness or recovery from injury

● stress

● poor forage quality

● seasonal weather changes

● naturally higher calorie requirements

Because weight loss may sometimes indicate an underlying medical problem, horses experiencing unexplained or rapid condition loss should be evaluated by a veterinarian before major dietary changes are made.

Once medical concerns have been addressed, nutrition often becomes the primary tool for rebuilding body condition.

Forage Should Remain the Foundation

Many owners are surprised to learn that simply improving forage quality can make a noticeable difference.

Horses are designed to consume forage for much of the day. Long-stem fiber supports:

● healthy hindgut fermentation

● digestive function

● saliva production

● natural chewing behavior

● steady calorie intake

When forage intake improves, horses often become better able to utilize the rest of their feeding program as well.

Rather than relying immediately on large grain meals, many horses benefit from maximizing forage quality first.

Digestibility Matters More Than Quantity

Feeding more hay does not always solve the problem.

If hay is overly mature, coarse, weather-damaged, or difficult to chew, an underweight horse may consume fewer usable nutrients than expected.

Digestible forage allows horses to extract more nutrition from every pound consumed.

Characteristics many owners look for include:

● leafy growth

● comfortable chewing texture

● good leaf retention

● clean, properly cured hay

● minimal dust and mold

Premium orchardgrass is often an excellent choice for horses needing to gain condition because it is typically soft, highly palatable, and readily consumed by many horses.

Horses that clean up their hay consistently often receive more total nutrition than those that sort through stemmy forage and leave significant waste behind.

For horses requiring additional calories, an orchardgrass/alfalfa blend may also be appropriate as part of an overall feeding program, depending on the horses nutritional needs and veterinary recommendations.

Encourage Consistent Forage Intake

An underweight horse cannot benefit from hay it refuses to eat.

Palatability is sometimes overlooked when evaluating forage, yet it can have a significant influence on total daily intake.

Many horses naturally eat more consistently when forage is:

● soft

● leafy

● fresh smelling

● free of excessive dust

● consistent from bale to bale

Stress, frequent travel, herd competition, or unfamiliar surroundings may all reduce appetite. During these periods, offering highly palatable forage may help encourage more regular eating.

Consistency also allows owners to better evaluate whether the feeding program is actually improving body condition.

Feed More Often Rather Than Feeding More at Once

The equine digestive system is designed for frequent forage consumption rather than large meals.

Whenever practical, offering forage more often throughout the day may support:

● steadier digestive function

● improved calorie intake

● healthier feeding behavior

● reduced boredom

Some underweight horses benefit from having forage available for much of the day, provided they do not have medical conditions requiring restricted intake.

Individual management should always reflect the horses overall health, metabolism, and nutritional goals.

Don’t Overlook Dental Health

One of the most common reasons older horses struggle to gain weight is declining dental efficiency.

A horse may appear eager to eat while quietly leaving behind much of the nutrition because chewing has become difficult.

Signs that warrant a dental evaluation include:

● dropping partially chewed hay (quidding)

● eating slowly

● excessive hay waste

● foul breath

● weight loss despite a good appetite

● long forage fibers in manure

Even premium hay becomes difficult to utilize if a horse cannot chew it effectively.

Routine dental care remains an essential part of long-term nutritional management.

Monitor Progress Gradually

Healthy weight gain rarely happens overnight.

Owners often see the best long-term results by monitoring:

● body condition score

● topline development

● appetite

● manure consistency

● coat quality

● energy level

Photographs taken every few weeks can provide a surprisingly accurate record of gradual improvement.

Small, consistent gains are generally preferable to rapid changes that may complicate digestive health or create unnecessary nutritional imbalances.

Every Horse Has Different Calorie Needs

No single feeding program works for every underweight horse.

Some require:

● greater forage digestibility

● additional protein

● increased calorie density

● more frequent meals

● improved forage acceptance

● treatment of underlying medical conditions

Age, breed, workload, climate, metabolism, and overall health all influence nutritional requirements.

The goal is not simply adding calories. The goal is providing the right calories through a feeding program that supports digestive health while allowing the horse to regain condition safely and comfortably.

Choosing Hay at the Barn

When selecting hay for a horse that needs to gain weight, avoid focusing only on the species listed on the bale. Two orchardgrass hays - or two alfalfa blends - may differ considerably in leafiness, maturity, aroma, and digestibility.

Experienced hay buyers often evaluate several characteristics together, including softness, leaf retention, cleanliness, smell, and overall consistency. Premium forage is less about finding a perfect species and more about finding hay that encourages steady intake while meeting the individual horses nutritional needs.

A knowledgeable forage supplier can help compare available lots and identify hay that best fits your horses condition and feeding goals.

FAQ

Is grain always necessary for an underweight horse?

Not always. Many horses benefit first from improvements in forage quality and overall feeding management. Grain or concentrates may be appropriate for some horses, depending on their individual nutritional requirements.

What type of hay is often recommended for horses that need to gain weight?

Many owners look for clean, leafy, digestible forage with good palatability. Premium orchardgrass is frequently chosen because many horses readily consume it, while orchardgrass/alfalfa blends may be appropriate for horses requiring additional calories.

Why isn’t simply feeding more hay always enough?

If hay is overly mature or difficult to chew, horses may not utilize its nutrients efficiently. Digestibility and intake are just as important as quantity.

How quickly should an underweight horse regain condition?

Healthy weight gain is usually gradual. Consistent nutrition, regular monitoring, and addressing any underlying medical concerns generally produce the safest long-term results.

Supporting Hard Keepers with Better Forage

While some horses gain weight extremely easily, others struggle to maintain body condition even with attentive care.

These “hard keepers” often require carefully managed feeding programs focused on maximizing forage intake, digestibility, and nutritional consistency.

Because forage represents the foundation of the equine diet, hay quality frequently becomes one of the most important factors influencing healthy weight maintenance.

What Is a Hard Keeper?

A hard keeper is a horse that has difficulty maintaining weight or muscle condition. This may occur because of:

● age,

● high activity levels,

● stress,

● poor dentition,

● digestive inefficiency,

● illness recovery,

● or naturally faster metabolism.

Some horses simply require more calories than owners initially expect.

Forage Intake Comes First

Owners sometimes focus immediately on adding grain or supplements.

However, improving forage quality and intake often creates the biggest long-term improvements.

Horses are naturally designed to consume forage continuously throughout much of the day. Consistent fiber intake supports:

● digestive health,

● hindgut fermentation,

● stable appetite,

● and healthy calorie consumption.

Palatability Matters Tremendously

Some hard keepers simply do not consume enough hay consistently. This is especially common among:

● stressed horses,

● picky eaters,

● senior horses,

● and competition animals.

Soft, leafy orchardgrass is frequently preferred because many horses consume it more readily and waste less compared to coarse forage. Improved palatability may help support:

● greater forage intake,

● more consistent eating,

● and better calorie consumption overall.

Digestibility Influences Weight Maintenance

Not all calories are equally accessible.

Highly mature, stemmy forage may contain fiber but provide lower digestibility.

Hard keepers often perform better on hay that is:

● softer,

● leafier,

● highly digestible,

● and easier to chew efficiently.

Quality orchardgrass is often valued because it provides comfortable texture while still supporting healthy fiber intake.

Consistency Helps Maintain Condition

Frequent forage changes can complicate weight management.

Differences in:

● digestibility,

● calorie density,

● texture,

● and palatability may influence intake and body condition.

Consistent forage quality allows owners to better evaluate:

● appetite,

● weight trends,

● manure quality,

● and feeding success.

Dental Health Should Always Be Evaluated

Many horses struggling to maintain weight have underlying dental issues.

Difficulty chewing coarse forage may limit effective calorie intake.

Regular dental examinations remain essential, especially for:

● senior horses,

● horses dropping feed,

● or animals wasting significant hay.

Stress Can Affect Appetite

Competition schedules, travel, herd dynamics, illness recovery, and environmental stress may all reduce forage intake.

Highly palatable hay often helps encourage more consistent eating during stressful periods.

Maintaining predictable feeding routines can also support:

● appetite stability,

● digestive comfort,

● and overall condition.

Weight Gain Should Be Gradual

Rapid nutritional changes are not always beneficial.

Healthy weight restoration usually occurs most successfully through:

● consistent forage intake,

● gradual calorie increases,

● digestive support,

● and stable feeding management.

The goal is sustainable body condition improvement rather than short-term weight spikes.

Individualized Nutrition Produces Better Results

Every hard keeper has different nutritional challenges.

Some require:

● greater digestibility,

● softer texture,

● more calorie density,

● or simply improved forage intake.

Thoughtful forage selection often provides the foundation for healthier long-term weight maintenance.

For many hard keepers, premium, palatable forage becomes one of the most valuable nutritional tools available.

FAQ

What causes horses to become hard keepers?

Age, stress, metabolism, dental issues, workload, and digestive efficiency can all contribute.

Why is orchardgrass helpful for hard keepers?

Many horses consume orchardgrass more readily because it is soft and palatable.

Can poor hay quality contribute to weight loss?

Yes. Coarse or poorly digestible forage may reduce effective calorie intake.

Should hard keepers receive unlimited hay?

Many benefit from consistent forage access, though feeding plans should still be individualized.

Why Some Horses Gain Weight Easily

Many horse owners feel frustrated when their horses gain weight despite seemingly modest feeding programs.

Meanwhile, other horses consume large amounts of feed while remaining lean.

These differences are not always the result of owner mistakes. Genetics, metabolism, activity level, and forage management all influence how efficiently horses maintain body condition.

Understanding why some horses are “easy keepers” can help owners make more informed nutritional decisions.

What Is an Easy Keeper?

An easy keeper is a horse that maintains or gains weight with relatively few calories.

Common easy keepers include:

• ponies,

• draft breeds,

• easy-keeping stock horses,

• and many lightly worked recreational horses.

These animals evolved to survive periods of limited forage availability.

Modern feeding conditions, however, often provide far more calories than these horses actually require.

Hay Still Contains Significant Calories

Owners sometimes focus heavily on grain while overlooking calories coming from forage.

Hay provides:

• digestible energy,

• sugars,

• fiber,

• and protein.

Some premium, highly digestible forage may contain more calories than owners realize.

This does not make quality hay “bad.”

It simply means forage should match the individual horse’s nutritional needs.

Metabolism Influences Weight Gain

Some horses utilize calories very efficiently.

Others naturally burn more energy through:

• movement,

• temperament,

• muscle metabolism,

• or workload.

Easy keepers may maintain weight on surprisingly modest calorie intake.

For these horses, even small feeding excesses can gradually contribute to:

• obesity,

• regional fat deposits,

• or metabolic stress.

Activity Levels Matter

Many modern horses live relatively sedentary lifestyles compared to horses performing regular work.

Limited exercise means fewer calories are burned each day.

When calorie intake exceeds energy expenditure over time, gradual weight gain occurs.

Even horses receiving no grain may gain excess condition if forage intake exceeds their actual needs.

Forage Consistency Influences Management

Changing hay frequently can make body condition management more difficult.

Differences in:

• digestibility,

• calorie density,

• sugar levels,

• and palatability

may influence how efficiently horses maintain weight.

Consistent forage allows owners to make more predictable nutritional adjustments.

Portion Size Is Often Underestimated

Many owners estimate hay portions visually.

However, two flakes may differ dramatically in weight depending on bale density.

Weighing forage often provides a much clearer picture of actual intake.

Small adjustments can sometimes create meaningful improvements over time.

Restricting Hay Too Severely Can Backfire

Some owners respond to weight gain by aggressively limiting forage.

Unfortunately, this may increase:

• stress,

• boredom,

• digestive discomfort,

• and undesirable feeding behaviors.

Horses are naturally designed for regular forage consumption.

The goal is usually selecting more appropriate forage and managing intake thoughtfully rather than eliminating fiber.

Body Condition Should Be Monitored Regularly

Weight gain often occurs gradually.

Helpful practices include:

• body condition scoring,

• regular photographs,

• neck crest evaluation,

• and observing fat deposits.

Early adjustments are generally easier than correcting severe obesity later.

Individualized Feeding Creates Better Results

No single feeding strategy works for every easy keeper.

Some horses benefit from:

• lower-calorie grass hay,

• controlled portions,

• slow feeders,

• increased exercise,

• or stricter NSC management.

Thoughtful forage selection and consistent feeding routines often provide the best long-term results.

Healthy weight management is rarely about dramatic restriction.

It is usually about steady, sustainable nutritional balance.

FAQ

Why do some horses gain weight so easily?

Genetics, metabolism, activity level, and feeding management all influence weight gain efficiency.

Can hay alone make horses overweight?

Yes. Hay still provides calories and energy.

Should easy keepers receive less hay?

Calorie intake often requires management, but horses still need adequate fiber.

Why is forage consistency important?

Consistent hay makes body condition and calorie management more predictable.

Weight Control Through Forage Management

For many animal owners, weight management can feel surprisingly difficult.

Some horses and livestock gain weight easily despite modest feeding programs, while others struggle to maintain condition even with careful nutritional support.

Because forage represents the largest portion of most herbivores’ diets, hay selection often plays a central role in long-term body condition management.

Understanding how forage influences calories, digestibility, and feeding behavior can help owners make more informed decisions.

Hay Is More Than Just Fiber

Many owners think of hay primarily as roughage.

However, forage also provides:

• calories,

• digestible nutrients,

• protein,

• and natural sugars.

Different hays vary dramatically in nutritional value depending on:

• species,

• maturity,

• harvest timing,

• weather,

• and storage conditions.

This means two bales may appear similar while affecting body condition very differently.

Easy Keepers Require Careful Management

Easy keepers are animals that maintain or gain weight efficiently.

This commonly includes:

• horses,

• miniature livestock,

• ponies,

• goats,

• and some camelids.

For these animals, forage management often focuses on:

• moderate calorie intake,

• consistent feeding routines,

• and preventing excessive weight gain.

Overconditioning may contribute to:

• metabolic stress,

• reduced mobility,

• and increased health risks.

Hard Keepers Need Digestible Calories

Not all animals struggle with excess weight.

Senior animals, performance horses, lactating animals, and certain breeds may have difficulty maintaining condition.

For these animals, owners often prioritize forage that is:

• more digestible,

• softer,

• highly palatable,

• and energy supportive.

Leafier hay with good digestibility may help improve calorie intake without requiring excessive concentrates.

Portion Control Matters

Even appropriate hay can create problems if fed inconsistently.

Many owners estimate hay portions visually, but flake size and bale density vary considerably.

Weighing hay often provides:

• greater consistency,

• more accurate calorie management,

• and easier feeding adjustments.

Small changes over time are usually more effective than dramatic restrictions.

Forage Consistency Reduces Guesswork

Frequent forage changes can complicate body condition management.

Differences in:

• calorie density,

• digestibility,

• and palatability

may influence intake and weight trends.

Consistent hay quality helps owners evaluate feeding programs more accurately.

This is especially important for:

• metabolic horses,

• senior animals,

• and picky eaters.

Slow Feeding Can Help

Many owners use slow feeders to:

• extend feeding time,

• reduce boredom,

• and moderate intake speed.

This can help mimic more natural grazing behavior while still supporting controlled forage consumption.

Slow feeding may also help reduce hay waste in some situations.

Digestive Health Should Not Be Ignored

Restricting forage too aggressively can create digestive and behavioral problems.

Animals designed for regular forage intake may experience:

• stress,

• ulcer risk,

• boredom,

• or abnormal feeding behavior

when forage becomes too limited.

The goal is not simply feeding less.

The goal is balancing healthy fiber intake with appropriate calorie management.

Matching Hay to the Individual Animal

No single forage works ideally for every animal.

Factors influencing forage selection include:

• age,

• metabolism,

• workload,

• digestive sensitivity,

• and body condition goals.

Thoughtful forage management supports:

• stable weight,

• digestive comfort,

• feeding consistency,

• and overall long-term health.

The most successful feeding programs are usually the most individualized.

FAQ

Can hay alone cause weight gain?

Yes. Hay still contains calories, and some animals gain weight very efficiently.

Why should hay be weighed?

Bale density and flake size vary significantly.

Is softer hay higher in calories?

Often, but not always. Digestibility and maturity influence energy value.

Can slow feeders help with weight management?

Yes. Slow feeders may help regulate intake speed and extend forage access.

Hay Considerations for Equine Metabolic Syndrome

Equine Metabolic Syndrome, commonly called EMS, has become increasingly common among modern horses, especially easy keepers and lightly worked animals.

For many owners, managing EMS requires a complete shift in how they think about forage, body condition, and long-term nutrition.

Because hay represents the foundation of most equine diets, forage selection often becomes one of the most important parts of successful metabolic management.

What Is Equine Metabolic Syndrome?

EMS is a condition involving abnormal insulin regulation and increased metabolic sensitivity.

Affected horses are often prone to:

• obesity,

• regional fat deposits,

• insulin dysregulation,

• and increased laminitis risk.

Many EMS horses appear outwardly healthy until hoof soreness or weight gain becomes more obvious.

Because horses vary significantly in metabolic sensitivity, feeding programs should always be individualized.

Why Forage Matters So Much

Most horses consume hay for many hours each day.

Even relatively small differences in forage quality can influence:

• calorie intake,

• sugar consumption,

• digestive stability,

• and body condition.

For EMS horses, many owners prioritize:

• consistent forage,

• moderate calorie density,

• clean hay,

• and careful NSC management.

The goal is supporting healthy fiber intake while reducing unnecessary metabolic stress.

Understanding NSC

NSC stands for non-structural carbohydrates.

This includes sugars and starches naturally present within forage.

Some EMS horses experience exaggerated insulin responses when consuming elevated sugar intake.

Because of this, owners often seek hay with moderate or lower NSC values.

However, no single NSC target works perfectly for every horse.

The ideal feeding program depends on:

• body condition,

• insulin sensitivity,

• activity level,

• age,

• and overall health.

Weight Management Is Central

Many EMS horses gain weight extremely efficiently.

Owners are often surprised by how few calories some easy keepers actually require.

Helpful practices frequently include:

• weighing hay,

• monitoring body condition regularly,

• using slow feeders,

• and adjusting intake gradually.

Small changes over time are often more sustainable than extreme restriction.

Consistency Reduces Nutritional Fluctuation

Frequent forage changes may complicate metabolic management.

Differences in:

• digestibility,

• calorie density,

• and sugar levels

can influence how horses maintain weight and respond nutritionally.

Consistent forage allows owners to evaluate body condition changes more accurately and reduce feeding guesswork.

Predictable nutrition often creates more stable long-term management.

Digestive Health Still Matters

Owners sometimes become so focused on lowering calories that they accidentally choose forage that is overly coarse or poorly digestible.

Fiber quality still matters tremendously.

Horses require forage for:

• digestive function,

• hindgut health,

• chewing behavior,

• and emotional comfort.

Even lower-calorie hay should still be:

• clean,

• appropriately digestible,

• and reasonably palatable.

Hay Testing Provides Valuable Information

Visual appearance alone cannot accurately determine forage sugars.

Laboratory testing can provide insight into:

• NSC,

• digestibility,

• protein,

• fiber,

• and moisture.

For horses with significant metabolic sensitivity or previous laminitis history, forage analysis can help owners make more informed feeding decisions.

Exercise and Lifestyle Also Matter

Nutrition is only one part of EMS management.

When medically appropriate, movement and exercise may help support:

• insulin sensitivity,

• weight management,

• and overall health.

Pasture access, stress levels, and seasonal management also influence metabolic stability.

Individualized Management Creates Better Results

No single hay works perfectly for every EMS horse.

Some horses thrive on carefully managed grass hay.

Others require stricter calorie control or more digestible forage.

Thoughtful feeding programs focus on:

• consistency,

• gradual adjustments,

• digestive support,

• and matching forage to the individual horse.

Long-term metabolic management is usually built through steady, sustainable decisions rather than drastic feeding changes.

FAQ

What is EMS in horses?

EMS stands for Equine Metabolic Syndrome, a condition involving insulin dysregulation and increased laminitis risk.

Should EMS horses eat low-sugar hay?

Many EMS horses benefit from careful NSC management and controlled calorie intake.

Why is body condition important in EMS?

Excess body fat may worsen metabolic sensitivity in susceptible horses.

Does hay testing matter for EMS horses?

Yes. Testing helps owners better understand forage nutrition beyond visual appearance.

Feeding Horses with Cushing’s Disease

Caring for a horse with Cushing’s disease often requires owners to think more carefully about nutrition, weight management, and overall metabolic health.

Many horses with Cushing’s disease, also known as PPID, continue living active and comfortable lives with thoughtful management. Forage selection frequently becomes one of the most important components of that long-term care.

Because every horse responds differently, individualized feeding programs are essential.

Understanding Cushing’s Disease

Pituitary Pars Intermedia Dysfunction, commonly abbreviated PPID, is a hormonal condition most commonly seen in older horses.

Affected horses may experience:

• changes in metabolism,

• altered body condition,

• muscle loss,

• abnormal hair coats,

• increased drinking and urination,

• and increased laminitis risk.

Not every horse shows identical symptoms.

Some horses primarily struggle with weight management, while others remain relatively stable for years with careful monitoring.

Why Forage Matters

Hay represents the largest portion of most horses’ diets.

For horses with PPID, forage quality can influence:

• calorie intake,

• digestive health,

• metabolic stability,

• and body condition management.

Many owners focus on selecting:

• consistent forage,

• moderate calorie density,

• clean hay,

• and appropriate sugar levels.

Because some horses with PPID are more metabolically sensitive, NSC management may become important.

Understanding NSC

NSC stands for non-structural carbohydrates, which primarily include sugars and starches.

Some horses with PPID also experience insulin dysregulation, making them more sensitive to elevated sugar intake.

This is why owners often seek forage with moderate or lower NSC levels.

However, nutritional needs still vary significantly between horses.

Some horses maintain weight easily and require calorie control.

Others struggle to hold body condition and may require more digestible forage.

Weight Management Challenges

PPID horses can sometimes become difficult to manage nutritionally because they may experience either:

• unwanted weight gain,

• or gradual muscle and condition loss.

This makes individualized feeding especially important.

Owners often benefit from monitoring:

• body condition,

• topline changes,

• appetite,

• and seasonal fluctuations.

Regular evaluation allows feeding programs to adjust gradually rather than react after significant condition changes occur.

Digestibility Matters for Older Horses

Many horses with PPID are seniors.

As horses age, chewing efficiency and digestive function may gradually decline.

Softer, more digestible forage may become helpful for:

• horses with dental wear,

• reduced appetite,

• or difficulty maintaining weight.

At the same time, excessively rich forage may complicate metabolic management in easy keepers.

Balance becomes extremely important.

Consistency Supports Stability

Frequent forage changes can make metabolic management more difficult.

Consistent hay quality allows owners to:

• monitor weight trends more accurately,

• maintain stable feeding routines,

• and reduce digestive disruption.

Gradual transitions are generally preferred whenever forage changes become necessary.

Many horses with PPID benefit from predictable feeding schedules and steady nutritional programs.

Clean Forage Is Important

Respiratory sensitivity and immune challenges may increase as horses age.

Dusty or moldy hay may contribute to:

• coughing,

• respiratory irritation,

• or reduced forage intake.

Clean, properly stored forage supports both palatability and overall health.

Feeding the Individual Horse

No single hay works perfectly for every horse with PPID.

Factors influencing forage selection include:

• insulin sensitivity,

• age,

• body condition,

• dental health,

• workload,

• and digestive function.

Thoughtful forage management helps owners create more stable, sustainable feeding programs over time.

The best feeding plans are rarely the most extreme.

They are usually the most consistent and individualized.

FAQ

What is PPID in horses?

PPID, commonly called Cushing’s disease, is a hormonal disorder most often affecting older horses.

Should horses with PPID eat low-sugar hay?

Some horses with PPID benefit from careful NSC management, especially if insulin dysregulation is present.

Why do older horses need softer hay?

Dental wear and reduced chewing efficiency may make softer forage easier to consume.

Does forage consistency matter for PPID horses?

Yes. Stable feeding programs often make body condition and digestive management easier.

Understanding the Link Between Hay and Laminitis

Laminitis is one of the most frustrating and emotionally difficult conditions many horse owners will ever manage. Horses that appear healthy one season can suddenly become sore, reluctant to move, or painfully sensitive in their feet. In many cases, owners are left searching for answers about grain, pasture, supplements, and medications while overlooking one of the largest parts of the horse’s daily diet: forage.

For horses prone to founder or laminitis, hay quality matters tremendously.

Not all hay is nutritionally identical. Different forage species, maturity levels, growing conditions, and harvesting practices can create major differences in sugar, starch, digestibility, and calorie levels. Understanding these differences can help owners make more informed feeding decisions and support long-term metabolic stability.

Why Hay Matters So Much

“Group of horses eating hay at the same time” by AndreasKermann via gettyimages.com

Most horses consume forage for the majority of the day. Even horses receiving concentrates or supplements still rely heavily on hay as their primary calorie source.

For metabolically sensitive horses, this becomes especially important because certain hays may contain elevated levels of non-structural carbohydrates, often abbreviated as NSC. NSC includes sugars and starches that can contribute to insulin dysregulation in susceptible horses.

While not every horse reacts the same way, many horses with:

• laminitis,

• Equine Metabolic Syndrome,

• obesity tendencies,

• or Cushing’s disease

benefit from carefully managed forage programs.

This does not necessarily mean horses must eat poor-quality hay. In fact, many horses thrive on premium forage that has been selected specifically for lower sugar content, appropriate maturity, and consistent nutritional characteristics.

Understanding Hay Sugars

Horse owners are often surprised to learn that hay can vary tremendously in sugar levels.

Factors influencing hay sugars include:

• forage species,

• weather conditions,

• sunlight exposure,

• plant maturity,

• fertilization,

• cutting schedules,

• and storage conditions.

For example, immature grasses harvested during periods of intense sunlight may contain higher sugar concentrations than more mature forage harvested under different conditions.

This is why visual appearance alone cannot always determine whether a hay is appropriate for a metabolic horse.

Soft, green, leafy hay may look ideal but still contain elevated sugar levels. On the other hand, extremely coarse hay may be less digestible and difficult for some horses to maintain body condition on.

The goal is balance.

Consistency Is Often Overlooked

One of the most important but underappreciated aspects of feeding metabolic horses is consistency.

Frequent dramatic changes in forage type can sometimes contribute to digestive upset, fluctuations in calorie intake, or unpredictable metabolic responses.

Horses generally do best when forage changes are gradual and predictable.

Consistent hay quality helps owners:

• better monitor body condition,

• manage weight more effectively,

• reduce feeding guesswork,

• and maintain stable digestive function.

For many owners, consistency becomes just as valuable as the hay itself.

Choosing Appropriate Hay Types

There is no single “perfect” hay for every horse with laminitis.

However, many owners and veterinarians commonly look for:

• moderate to lower NSC levels,

• clean forage,

• minimal dust,

• good digestibility,

• and consistent harvest quality.

Grass hays are often preferred over richer legume-heavy options for easy keepers, though every horse should be evaluated individually.

Orchardgrass, timothy, bermudagrass, and carefully managed mixed grass hays are frequently used in metabolic feeding programs depending on the horse’s condition, activity level, and overall calorie needs.

Hay testing can also be extremely helpful.

Laboratory forage analysis provides a much clearer nutritional picture than visual evaluation alone. Testing allows owners to better understand:

• sugar levels,

• protein,

• fiber,

• digestibility,

• and mineral balance.

This can be especially useful for horses with recurring laminitis episodes or difficult weight-management situations.

The Importance of Weight Management

Excess body condition is a major risk factor for many metabolic horses.

Even small amounts of gradual weight gain over time can increase stress on the horse’s metabolic system. Unfortunately, many easy keepers require surprisingly few calories to maintain weight.

Owners sometimes unintentionally overfeed because the horse appears hungry or because traditional feeding programs are designed for higher-calorie needs.

Forage selection can help manage calorie intake more effectively while still supporting:

• digestive health,

• chewing behavior,

• and emotional well-being.

Horses are naturally designed to consume forage regularly throughout the day. Severely restricting hay can sometimes create additional digestive and behavioral challenges.

The goal is not simply feeding less.

The goal is feeding smarter.

Practical Feeding Considerations

Owners managing laminitis-prone horses

often benefit from:

tributeequinenutrition.com by Tribute Equine Nutrition

• weighing hay portions rather than estimating,

• using slow feeders when appropriate,

• maintaining consistent feeding schedules,

• monitoring seasonal weight fluctuations,

• and introducing forage changes gradually.

Pasture management also matters tremendously. In some situations, pasture sugars may exceed those found in properly selected hay.

Working closely with a veterinarian and knowledgeable forage provider can help owners develop a more individualized feeding approach.

Small Changes Can Make a Big Difference

Many horses with metabolic challenges continue living comfortable, active lives with thoughtful nutritional management.

While hay alone is rarely the only factor involved in laminitis, forage quality often plays a central role in long-term success.

Understanding forage characteristics, selecting consistent hay sources, and matching nutrition to the individual horse can help owners make more confident feeding decisions.

Every horse is different, and forage programs should reflect those individual needs rather than relying on one-size-fits-all feeding practices.

FAQ

What does low-NSC hay mean?
