Why Palatability Matters in Digestive Health

Palatability Is More Than Taste

Palatability describes how appealing forage is and how willingly a horse consumes it.

Aroma, softness, leafiness, stem size, cleanliness, familiarity, moisture, and chewing comfort may all influence intake.

A horse may smell a new bale carefully, take several stems, and then decide whether to continue. Another may eat the leaves while leaving coarse stems. These behaviors can reveal preference, maturity, contamination, or dental discomfort.

The Horse Must Eat the Forage to Benefit

A ration can look appropriate on paper while providing much less nutrition than expected. A horse offered twenty pounds may consume only sixteen after sorting and waste are considered.

That difference can affect calorie intake, fiber consumption, body condition, feeding time, and digestive routine. Actual consumption is especially important for seniors, hard keepers, recovering horses, and animals with limited appetites.

Palatability Supports Regular Forage Intake

Frequent chewing encourages saliva production and keeps forage entering the stomach and hindgut. A palatable hay can help a horse begin eating promptly, return to the feeder regularly, and avoid unintended long gaps without forage.

Palatable forage does not prevent or cure gastric ulcers or colic. It supports a more consistent intake pattern within a broader management plan.

Softness Often Improves Acceptance

Many horses readily consume leafy, fine-stemmed, pliable hay. Soft orchardgrass is often useful for seniors, picky eaters, and hard keepers because it tends to be comfortable to chew and broadly accepted.

Timothy, smooth bromegrass, prairie grass, bermudagrass, and other grass hays can also be highly palatable when harvested and stored well. The individual lot matters more than assumptions about the species.

Dental Comfort Can Look Like Preference

A horse may appear picky when chewing is painful. Quidding, slow eating, foul breath, weight loss, head tilting, or sudden rejection of firmer hay warrants a dental evaluation.

Softer forage may improve comfort but should not be used to conceal an untreated dental problem.

Palatable Does Not Mean Nutritionally Ideal

A hard keeper may benefit from a soft orchardgrass or orchardgrass/alfalfa blend. An easy keeper may eagerly consume the same forage but receive more calories than needed.

Palatability must be considered alongside body condition, activity level, metabolic status, dental health, forage analysis, and total daily intake.

Choosing Hay at the Barn

Open a bale and examine the whole flake. Look for a clean aroma, flexible stems, retained leaves, limited dust, and consistency throughout the lot.

The practical measure of palatability is whether the individual horse eats the hay comfortably and consistently in an amount appropriate for its nutritional needs.

FAQ

What makes hay palatable?

Aroma, softness, leafiness, stem size, freshness, cleanliness, familiarity, and chewing comfort all contribute.

Is the most palatable hay always healthiest?

No. A highly appealing hay may provide more calories, protein, or sugar than a particular horse requires.

Why does my horse eat leaves but leave stems?

The stems may be coarser, less appealing, or more difficult to chew. Maturity and dental comfort should be considered.

When should hay refusal concern me?

Sudden refusal accompanied by reduced manure, colic signs, fever, depression, weight loss, difficulty swallowing, or abnormal breathing requires prompt veterinary guidance.

Dust, Mold, and Respiratory Stress

A Horse Breathes Where It Eats

A horse places its nose directly into forage for hours each day. Every time it separates a flake or pulls hay from a feeder, small particles may become airborne around the nostrils. Some are ordinary plant fragments; others may include soil, pollen, mold spores, bacteria, or damaged leaf material.

Not every visible particle proves that hay is moldy, but a bale that creates a heavy cloud, smells musty, feels damp, or contains discolored and matted areas deserves careful attention. Persistent coughing, nasal discharge, reduced exercise tolerance, wheezing, or increased effort at rest should be evaluated by a veterinarian.

Dust Is More Than Dry Plant Material

Airborne material around hay may contain broken stems and leaves, soil incorporated during harvest, pollen, fungal spores, bacteria, and fine fragments produced during handling. Smaller particles can travel farther into the respiratory tract and may aggravate susceptible horses.

One horse may tolerate a hay lot without obvious difficulty while another coughs during every feeding. Previous respiratory disease, age, time indoors, ventilation, bedding, exercise demands, and total exposure all influence the response.

Mold Is a Forage-Quality Warning

Mold commonly develops when forage is baled too wet or exposed to moisture during storage. Warning signs include a musty or sour odor, visible white, gray, or dark areas, unusual warmth, dampness, clumping, and excessive dust when the bale is opened.

Obviously moldy or spoiled hay should not be fed. Soaking, steaming, shaking, or mixing it with better hay should not be used to rescue forage that is genuinely unsuitable.

Species Does Not Guarantee Cleanliness

Orchardgrass, timothy, smooth bromegrass, prairie grass, bermudagrass, alfalfa, and blends can all be clean and properly made. Any of them can also become dusty or moldy when harvest, curing, storage, or handling conditions are poor.

Orchardgrass is often soft and leafy, timothy may have firmer stems, bermudagrass is usually fine stemmed, and alfalfa leaves can shatter when very dry. These traits affect the physical character of the hay, but the individual lot matters more than the species name.

The Whole Barn Environment Matters

Changing hay alone may not solve a respiratory problem when bedding, ventilation, sweeping, overhead hay storage, indoor arenas, dried manure, or neighboring stalls continue to create airborne material.

Useful management steps may include increasing safe turnout, improving airflow, removing horses before sweeping or blowing aisles, storing hay away from the breathing zone, and selecting low-dust bedding. Clean rye or wheat straw can be useful bedding, but a dusty or moldy lot may be inappropriate for a sensitive horse.

Soaking and Steaming Require Care

Wetting clean hay can suppress some airborne material, but soaking may also remove soluble nutrients and minerals. Wet hay spoils more quickly and should be drained, fed promptly, and discarded when uneaten.

Purpose-built high-temperature steamers may reduce respirable particles and microorganisms more consistently than improvised warming, but neither method makes spoiled hay safe. Veterinary guidance is appropriate when respiratory disease is suspected.

Choosing Hay at the Barn

Begin with cleanliness rather than species. Open more than one bale, inspect the interior, smell the forage without inhaling deeply into it, and observe how much material becomes airborne during ordinary handling.

Soft orchardgrass may be especially helpful for a senior or picky eater, but clean timothy, smooth bromegrass, prairie grass, bermudagrass, alfalfa, or a suitable blend can also work. The practical goal is clean, properly cured, low-dust forage stored and handled with care.

FAQ

Is dusty hay always moldy?

No. Dust may consist of plant fragments, soil, pollen, or shattered leaves. Excessive dust is still undesirable, especially for a respiratory-sensitive horse.

Can soaking make moldy hay safe?

No. Soaking may suppress dust in otherwise acceptable forage but should not be used to salvage moldy, musty, or spoiled hay.

Is orchardgrass less dusty than timothy?

Not automatically. Dust levels depend more on harvest, dryness, handling, and storage than on species alone.

When is breathing difficulty an emergency?

Marked effort at rest, nostril flaring, abdominal heaving, weakness, distress, or failure to recover normally warrants immediate veterinary attention.

Supporting Horses Prone to Colic

Few situations cause more immediate concern for a horse owner than signs of colic.

Pawing, looking at the flank, repeatedly lying down, rolling, sweating, reduced appetite, or passing less manure may all indicate abdominal pain.

Colic is not one specific disease. It is a broad term for abdominal pain that can result from many different conditions, ranging from relatively mild gas or impaction to an intestinal displacement or other emergency. Because the possible causes vary so widely, no hay type or feeding practice can guarantee that a horse will never colic.

The practical goal is to reduce avoidable risks, create a stable digestive routine, and recognize changes early enough to involve a veterinarian promptly. For a horse with a history of colic, thoughtful forage management can be an important part of that larger plan.

A Previous Colic Episode Deserves Attention

Some horses experience one isolated episode and never have another. Others develop recurring patterns related to dental problems, hydration, feed changes, sand exposure, parasites, stress, or an underlying medical condition.

Owners of horses that have colicked before should work with their veterinarian to review:

● previous diagnoses and treatments

● seasonal timing of episodes

● recent feed or hay changes

● water consumption

● dental history

● parasite-control practices

● turnout and exercise changes

● manure patterns

● medication use

A feeding program can support digestive health, but it cannot correct every cause of recurring abdominal pain. Repeated episodes deserve professional investigation rather than a series of uncoordinated feed changes.

Keep the Forage Program Predictable

The horses hindgut contains a large microbial population that adapts to the fiber and nutrients entering the digestive tract. Sudden changes in hay species, maturity, digestibility, or feeding amount may force that population to adjust rapidly.

Even a new load of the same forage species can differ from the previous one because of:

● field conditions

● cutting date

● plant maturity

● growing region

● weather during harvest

● storage and curing

Consistency does not mean every bale must look identical. It means avoiding unnecessary swings in forage type and nutritional character whenever possible.

For horses with a sensitive digestive history, dependable sourcing and gradual transitions are especially valuable.

Make Hay Changes Gradually

When a new hay must be introduced, blending the old and new forage gives the horse time to adapt to differences in texture, aroma, fiber, and nutritional density.

A practical transition often begins with a small proportion of the new hay, followed by gradual increases over several days or longer. The exact pace should reflect the horses history, the difference between the two hays, and veterinary guidance.

During the transition, monitor:

● appetite

● manure consistency and output

● drinking behavior

● abdominal comfort

● hay waste

● attitude

A horse that has previously reacted poorly to dietary change may need a slower transition than a horse with no digestive concerns.

Fresh Water Is Essential

Dry forage depends on adequate water intake moving through the digestive system.

A horse that drinks poorly may be more vulnerable to dry intestinal contents, particularly during cold weather, travel, heavy sweating, or abrupt changes in water source.

Good daily practices include:

● providing continuous access to clean, fresh water

● checking automatic waterers for adequate flow

● preventing freezing during winter

● cleaning troughs and buckets regularly

● monitoring intake when traveling

● noticing whether an individual horse drinks less than usual

Water availability should never be assumed simply because a trough or automatic waterer is present. Confirm that it is clean, functioning, and accessible to every horse in the group.

Match Hay Texture to Chewing Ability

Forage must be chewed effectively before the horse can use it well.

Coarse stems that are poorly chewed, combined with dry feed and inadequate water intake, may create additional concern for horses prone to impaction. This is particularly important for senior horses and animals with dental wear.

Watch for:

● quidding, or dropping partially chewed hay

● long forage fibers in manure

● slow eating

● excessive stem waste

● declining body condition

● unusual mouth odor

● reluctance to eat firmer hay

A soft, leafy forage may improve intake for some horses, but changing hay does not replace regular dental care. Horses with recurring colic concerns should have dental needs evaluated on a schedule appropriate to the individual.

Provide Regular Forage Without Ignoring Calories

Long gaps without forage are inconsistent with the horses natural feeding pattern.

Dividing the daily hay allowance into more frequent portions may support steadier fiber intake and reduce the tendency to consume a large meal rapidly.

Options may include:

● additional hay feedings

● a properly designed slow feeder

● several feeding stations

● a later evening feeding

● controlled pasture access where appropriate

Consistent forage access does not automatically mean unlimited intake. Easy keepers and horses with metabolic concerns may still require measured portions. The objective is to distribute an appropriate amount of forage across the day rather than allowing repeated long periods with nothing acceptable to eat.

Use Concentrates Thoughtfully

Some horses require concentrates to meet energy, protein, vitamin, or mineral needs.

However, large concentrate meals should not displace the forage foundation of the diet.

For a horse with a sensitive digestive history, consider whether:

● the current concentrate amount is necessary

● large meals can be divided

● more calories can come from digestible fiber

● the horse receives adequate forage before concentrates

● several supplements are adding unnecessary complexity

Any change should be made gradually. Replacing one abrupt feeding strategy with another can create a new problem rather than solving the first one.

Reduce Sand Exposure

Horses fed from sandy soil or very short, overgrazed areas may ingest soil while collecting dropped leaves and stems.

Practical ways to reduce exposure include:

● using a feeder, tub, or hay rack

● placing rubber mats or catch surfaces beneath feeders

● avoiding feeding directly on bare sandy ground

● maintaining adequate forage so horses are less likely to sift through dirt

Sand management needs vary by property and region. A veterinarian can help determine whether a horses environment and history warrant additional monitoring or a specific management plan.

Clean Hay Still Matters

Moldy, spoiled, or heavily contaminated forage should not be fed.

Clean hay supports more predictable intake and reduces the chance that a horse will sort aggressively, refuse meals, or consume only selected portions. Evaluate each lot for:

● visible mold

● musty or unusual odor

● excessive dust

● heat within the bale

● moisture damage

● foreign material

● inconsistent or weathered sections

A bale that has been stored properly can still vary inside, so owners should pay attention while opening and feeding it rather than judging only the outside.

Movement and Routine Support the Larger Program

Turnout and regular movement may support normal digestive activity, but exercise alone cannot prevent colic.

Abrupt changes in stabling, workload, turnout, or feeding schedule can occur together during travel, competition, injury, or seasonal transitions. When possible, make these changes gradually and preserve familiar forage and watering routines.

A horse on stall rest or reduced activity may require a revised feeding plan. Work with the veterinarian managing the underlying condition rather than simply continuing the previous ration unchanged.

Know What Is Normal for Your Horse

Early recognition begins with familiarity.

Owners who know a horses ordinary appetite, manure output, drinking behavior, attitude, and resting habits are more likely to notice subtle changes.

Pay attention to:

● leaving hay or grain unfinished

● passing less manure

● unusually dry or small manure

● repeated flank watching

● pawing or stretching

● lying down more than usual

● sweating without an obvious reason

● reduced interest in water

● unexplained depression or restlessness

These signs do not reveal the cause or severity of the problem. They indicate that the horse should be evaluated, especially when several signs occur together.

Treat Suspected Colic as a Veterinary Concern

A horse showing signs of colic should be discussed with a veterinarian promptly. Some serious conditions begin with mild or intermittent signs, and the outward behavior does not reliably identify which part of the digestive tract is involved.

While waiting for professional instructions:

● keep yourself and the horse safe

● remove access to feed unless the veterinarian advises otherwise

● observe manure, water intake, and behavior

● record the time signs were first noticed

● take vital signs if you know how and can do so safely

● do not give medication unless directed by a veterinarian

Walking may be appropriate when it keeps the horse comfortable and safe, but neither the horse nor handler should be exhausted. A horse that is violently rolling or thrashing can be dangerous, and personal safety comes first.

Choosing Hay at the Barn

There is no “colic-proof” hay.

The most useful forage is clean, appropriately mature, easy for the horse to chew, and consistent enough to introduce and feed predictably. Soft orchardgrass may be a good fit for a senior or selective eater. Properly made timothy, smooth bromegrass, prairie grass, bermudagrass, or another grass hay may suit a different horse depending on body condition, chewing ability, and the characteristics of the individual lot.

When comparing hay, ask about:

● harvest maturity

● stem size and flexibility

● leaf retention

● storage history

● consistency within the lot

● the type of horse for which the hay is best suited

The species name is useful, but it should never replace an evaluation of the actual hay or the individual horse.

FAQ

Can the right hay prevent colic?

No hay can prevent every form of colic. Clean, consistent forage, adequate water, gradual dietary transitions, dental care, and thoughtful management may reduce certain avoidable risks, but colic can still occur.

What is the best hay for a horse that has colicked before?

There is no single best species. Choose clean, palatable forage with a texture and nutritional profile suited to the horse. The history and suspected cause of previous episodes should guide the decision with veterinary input.

Can changing hay cause colic?

A sudden change in forage may increase digestive risk in some horses because the hindgut must adapt to a new fiber and nutrient profile. Introduce new hay gradually whenever possible.

Should a colic-prone horse have unlimited hay?

Not automatically. Frequent forage access may be useful, but total intake must still match body condition, metabolism, and medical needs. Measured hay can be divided or slow-fed to extend eating time.

Does soaking hay prevent impaction colic?

Soaking changes the moisture content of hay but does not guarantee prevention. Hydration, water intake, dental function, forage texture, movement, and the horses medical history all matter. Use soaked forage only when it fits an individualized management plan.

When should I call the veterinarian?

Call promptly whenever you suspect colic, especially if signs are severe, persistent, recurrent, or of unknown duration. Early veterinary assessment is important because mild outward signs do not always indicate a mild underlying problem.

Hay Texture and Digestive Comfort

When horse owners evaluate hay, they often begin with color, smell, and forage species. Those characteristics are important, but the way hay feels can be just as meaningful.

Hay texture influences how comfortably a horse chews, how eagerly it eats, how much it wastes, and how consistently it consumes forage throughout the day. A soft, leafy hay may be ideal for a senior horse or selective eater, while another horse may comfortably consume a somewhat more mature grass hay that provides substantial chewing fiber.

Texture alone does not determine nutritional quality, and there is no single texture that is best for every horse. However, understanding the relationship between texture, chewing, forage intake, and digestive comfort can help owners select hay that better fits the individual animal.

What Does Hay Texture Mean?

Texture describes several physical characteristics of forage rather than one simple quality.

When owners handle a flake of hay, they may notice differences in:

● stem thickness

● stem flexibility

● leaf content

● brittleness

● softness

● seed heads

● dustiness

● overall uniformity

These characteristics are influenced by forage species, but species is only part of the explanation.

Plant maturity at harvest often has a major effect. Younger plants are generally leafier, finer stemmed, and more flexible. As forage matures, stems become larger and more fibrous, while the proportion of leaves may decline.

Weather, curing conditions, baling moisture, storage, and handling also affect how the finished hay feels. Even two cuttings from the same field may have noticeably different textures.

Chewing Is the Beginning of Digestion

Digestion begins before hay reaches the stomach.

A horse must first grasp, tear, and grind forage into smaller particles. Effective chewing helps mix the hay with saliva and prepares it for the rest of the digestive process.

Appropriate forage texture encourages:

● thorough chewing

● regular saliva production

● comfortable swallowing

● steady intake

● more efficient use of the hay

Saliva helps moisten feed and provides buffering within the upper digestive tract. Long- stem forage naturally requires more chewing than many concentrated feeds, which is one reason hay remains so important in equine feeding programs.

Hay should provide enough physical structure to encourage normal chewing without being so coarse that the horse struggles to process it comfortably.

Soft Hay Is Often Easier to Accept

Many horses show a clear preference for soft, leafy forage.

This is especially common among:

● senior horses

● horses with dental wear

● picky eaters

● hard keepers

● horses recovering from illness

● animals experiencing reduced appetite

Soft orchardgrass is often useful in these situations because it commonly combines fine stems, good leaf retention, and broad palatability. Horses that aggressively sort through coarse hay may consume a softer orchardgrass more completely.

Timothy can also be soft and appealing when harvested at an appropriate stage, although later-maturity timothy may contain firmer stems and more pronounced seed heads. Smooth bromegrass, bermudagrass, prairie grass, and other grass hays likewise vary depending on maturity and production conditions.

The name of the forage does not guarantee the texture of the bale.

Coarser Hay Is Not Automatically Poor Hay

Softness is valuable, but coarse hay should not automatically be classified as low quality.

Some healthy adult horses comfortably chew and utilize moderately mature forage. A slightly firmer hay may suit certain maintenance horses or easy keepers when its nutritional characteristics match their needs.

More mature forage often contains:

● greater structural fiber

● larger stems

● lower digestibility than earlier-cut hay

● potentially lower calorie density

Those characteristics may be appropriate in some feeding programs. However, extremely stemmy forage can become difficult for horses with poor teeth, reduced appetite, or higher calorie needs.

The important distinction is between appropriately mature forage and hay that is excessively coarse, weather damaged, unpalatable, or poorly handled.

A hay does not need to feel delicate to be useful, but it should remain clean, properly cured, and suitable for the horse expected to eat it.

Texture Influences How Much Hay a Horse Actually Consumes

The amount of hay offered is not always the amount consumed.

A horse may pull apart a flake, eat the leaves and finer stems, and leave the coarsest portions behind. Owners sometimes interpret the remaining hay as evidence that the horse has received enough forage, even though a substantial portion was never eaten.

Selective eating can reduce actual intake and create long periods without meaningful forage access.

Watch for:

● thick stems consistently left in the feeder

● piles of sorted hay beneath a rack

● leaves consumed while seed heads remain

● repeated trampling of unwanted portions

● significant differences between hay offered and hay eaten

Some sorting is normal. Horses naturally make choices while eating. The concern is persistent waste that limits nutritional intake or leaves the horse without acceptable forage for much of the day.

Dental Health Changes Texture Requirements

A young horse with healthy teeth may handle a wide range of hay textures. A senior horse with missing or worn teeth may not.

Dental discomfort or reduced grinding ability can make even nutritionally appropriate forage difficult to consume.

Possible signs include:

● slow chewing

● quidding, or dropping partially chewed hay

● long forage fibers in manure

● declining body condition

● unusual head movements while eating

● excessive sorting or waste

● reluctance to eat coarse stems

A softer hay may improve comfort, but changing forage should not replace a dental examination. Dental abnormalities, pain, or missing teeth require professional evaluation.

Some horses with advanced dental limitations may eventually need chopped forage, soaked hay products, or another veterinarian-approved fiber source because they can no longer process long-stem hay effectively.

Brittle Hay Creates a Different Kind of Texture Problem

Hay can appear fine stemmed yet still be unpleasant to eat if it is excessively dry or brittle.

Brittle forage may shatter during handling, causing valuable leaves to fall away before the hay reaches the feeder. This can leave the horse with a larger proportion of stems while the most nutritious leaf material collects in the bottom of the bale, delivery vehicle, or storage area.

Excessive leaf loss may result from:

● overly dry baling conditions

● rough handling

● repeated movement

● prolonged storage

● weather damage

● naturally fragile forage, especially some legume hays

Alfalfa and orchardgrass/alfalfa blends can be especially affected by leaf loss because many of their desirable nutrients are concentrated in the leaves.

Careful handling helps preserve both texture and feeding value.

Dustiness Is Part of the Texture Experience

Hay texture is not limited to stems and leaves. Fine particles and dust also affect how comfortably a horse consumes forage.

A horse may bury its nose deeply into a feeder while eating, placing dust and plant particles close to the airways. Excessively dusty hay may contribute to coughing, nasal irritation, or reduced interest in eating, particularly in horses with respiratory sensitivity.

Dust may come from:

● soil incorporated during harvest

● damaged plant material

● excessive leaf shatter

● mold growth

● poor storage

● repeated handling

Visible mold, a musty odor, unusual heat, or obvious spoilage are reasons not to feed the hay.

Low-dust forage is especially important for horses with known respiratory disease.

Veterinary guidance should be sought when a horse coughs regularly, shows nasal discharge, has increased breathing effort, or appears intolerant of ordinary hay.

Texture and Digestibility Are Related, but Not Identical

Softer, leafier forage is often more digestible than highly mature, stem-heavy hay.

However, texture cannot provide a complete nutritional analysis.

Two hays with a similar feel may differ in:

● digestible energy

● protein

● fiber fractions

● sugar and starch

● mineral content

● moisture

Likewise, a coarse-looking hay may contain nutritional characteristics that are appropriate for one horse but unsuitable for another.

Visual and physical evaluation help determine whether a horse is likely to chew and accept the hay. Laboratory forage analysis provides additional information about what the hay contains.

Both forms of evaluation are useful.

Sudden Texture Changes May Affect Intake

Horses often notice a change in texture immediately.

A horse accustomed to soft orchardgrass may hesitate when abruptly offered a firm, mature hay. Another horse used to prairie grass may initially sort through a much leafier blend simply because it is unfamiliar.

The digestive system also needs time to adapt when a change in texture reflects a broader change in forage maturity, species, or nutritional composition.

When practical, introduce new hay gradually by blending it with the previous forage over several days.

During the transition, monitor:

● appetite

● manure consistency

● water intake

● chewing behavior

● hay waste

● signs of abdominal discomfort

A change in preference does not always mean the new hay is poor quality. Sometimes the horse simply needs time to become familiar with it. However, persistent refusal deserves investigation.

Water Intake Remains Essential

Even excellent hay requires adequate water for safe digestion.

Horses consuming dry forage need continuous access to clean, fresh water. Water intake can decline during cold weather, travel, changes in water source, or illness.

Owners can support hydration by:

● checking water sources daily

● preventing freezing in winter

● cleaning troughs and buckets regularly

● offering salt as appropriate

● monitoring horses during travel

● noticing changes in normal drinking patterns

Dry, coarse forage may be particularly difficult for a horse that is drinking poorly, but soft hay does not eliminate the need for adequate hydration.

Reduced water intake, decreased manure output, abdominal discomfort, repeated lying down, pawing, or loss of appetite require prompt veterinary attention.

Match Texture to the Horses Actual Needs

The best hay texture depends on the individual animal.

A senior hard keeper may need soft, leafy orchardgrass or an orchardgrass/alfalfa blend that encourages intake and provides greater nutritional density.

A mature maintenance horse may do well on properly made prairie grass, smooth bromegrass, bermudagrass, timothy, or moderately mature orchardgrass.

An easy keeper may require carefully portioned forage with moderate energy value, but the hay should still be clean and palatable enough to support steady fiber intake.

Consider:

● age

● dental health

● body condition

● workload

● metabolic status

● digestive history

● eating speed

● tendency to waste hay

The objective is not to select the softest hay available. It is to choose a texture the horse can chew comfortably and consume consistently while meeting the broader nutritional goal.

Choosing Hay at the Barn

Evaluating texture is one of the best reasons to handle hay before purchasing it.

Separate a flake and examine the entire sample rather than looking only at the outside of the bale. Run your hand through it. Bend several stems. Look at the proportion of leaves to stems and notice how much material falls away.

Quality hay should match its intended use.

For a senior or selective eater, look for pliable stems, good leaf retention, cleanliness, and a pleasant aroma. For a healthy maintenance horse, somewhat firmer forage may be entirely appropriate if it remains clean, well cured, and readily consumed.

Ask the hay supplier about:

● forage maturity

● cutting

● growing region

● stem characteristics

● leaf retention

● consistency throughout the lot

A knowledgeable supplier should be able to explain why one hay may suit a particular horse better than another without pretending that one texture is ideal for every animal.

FAQ

Is soft hay always better for horses?

No. Soft hay is often valuable for seniors, picky eaters, and horses with dental limitations, but healthy adult horses may comfortably consume a range of textures. The hay should match the horses chewing ability and nutritional needs.

Can coarse hay cause colic?

Coarse texture alone does not mean a horse will develop colic. Colic has many possible causes. However, forage that reduces intake, is poorly chewed, accompanies inadequate water consumption, or represents an abrupt dietary change may contribute to digestive concerns in some horses.

Why does my horse eat the leaves but leave the stems?

The horse may prefer the softer, more palatable portions or may have difficulty chewing coarse stems. Forage maturity, dental health, and individual preference should all be considered.

Is orchardgrass softer than timothy?

Orchardgrass is often softer and leafier, particularly when harvested at an appropriate stage. Timothy may have firmer stems and seed heads, although high-quality early-cut timothy can also be soft and palatable.

Does hay texture reveal its sugar or calorie content?

Not reliably. Texture may offer clues about maturity and digestibility, but laboratory testing is needed to evaluate sugar, starch, energy, protein, and other nutritional characteristics accurately.

Should I change hay if my horse wastes the coarse portions?

Persistent waste is worth evaluating. The horse may need a different forage texture, dental care, a better feeder, or a more appropriate hay lot. Determine what is being left behind before making a gradual change.

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.

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.

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?

Low-NSC hay refers to forage with lower levels of sugars and starches, which may be beneficial for horses with metabolic concerns.

Is alfalfa safe for horses with laminitis?

Some horses tolerate limited alfalfa well, while others may do better on primarily grass-based forage programs. Individual needs vary.

Can soaking hay reduce sugar?

Soaking hay may reduce some water-soluble carbohydrates, though results vary depending on hay type and soaking duration.

Why does consistency matter for metabolic horses?

Consistent forage helps reduce nutritional fluctuations and makes body condition management easier.
