What Foods Do Horses Like to Eat? The Complete Feeding Guide Every Owner Needs

Why Your Horse’s Dinner Plate Matters More Than You Think

If you have ever stood at a paddock fence and watched a horse’s ears prick up the second you rustle a feed bag, you already know these animals are serious about food. Horse owners ask this question constantly, and for good reason: get the answer wrong and you risk colic, weight problems, or a horse that is simply miserable. Get it right and you have a calm, healthy animal that thrives for 25 to 30 years.

What foods do horses like to eat? In short, horses are grazing herbivores who prefer grass, hay, and fibrous plants above everything else, with sweet treats like apples and carrots as their favorite occasional extras. This guide breaks down exactly what horses eat, what they should never touch, and how to build a feeding routine that keeps them healthy from breakfast to the last hay net of the night.

I have spent years around barns and boarding facilities, watching feeding programs succeed and fail. The horses that stayed soundest were almost never the ones on the fanciest grain. They were the ones whose owners understood forage first, treats second, and toxic plants never.

What Do Horses Like to Eat the Most?

Horses like grass, hay, and fresh pasture the most, since their digestive systems evolved to process fibrous plant material almost continuously. Among treats, most horses prefer sweet, crunchy foods such as apples, carrots, and peppermints. On average, a horse needs 1.5 to 2 percent of its body weight in forage daily, roughly 15 to 20 pounds for a 1,000 pound horse, according to Kentucky Equine Research.

That short paragraph answers the core question, but the real value for any horse owner comes from understanding the full picture: daily staples, safe treats, dangerous foods, and the wild diet horses evolved to eat.

What Do Horses Eat in the Wild?

Before domestication, horses were nomadic grazers roaming open plains for up to 16 hours a day. Wild and feral horses today, like the mustangs of the American West, still follow this pattern closely.

In the wild, horses eat:

• Grasses: The foundation of the natural equine diet, including native prairie grasses, wild rye, and bluestem
• Shrubs and woody plants: Eaten during lean seasons when grass is scarce
• Bark and twigs: A survival food in winter months
• Wild herbs and forbs: Broadleaf plants that add mineral variety
• Seeds and fallen fruit: Occasional, opportunistic snacks

According to Kentucky Equine Research, horses on pasture typically graze for around 16 hours out of 24, consuming roughly 1 to 2 pounds of dry matter per hour. This constant, slow-and-steady grazing pattern is the single biggest clue to understanding domestic feeding needs. Horses were never built for two or three big meals. They were built to nibble almost nonstop.

This is the piece many new owners miss. I have watched horses develop stomach ulcers and stall-weaving habits simply because they went too many hours without forage in front of them. The wild grazing pattern is not a nice-to-know fact. It is the blueprint for every healthy feeding program.

What Foods Do Horses Like to Eat Every Day?

Domesticated horses cannot roam 20 acres of open prairie, so owners have to recreate that natural grazing rhythm through structured feeding. Here is what makes up the daily menu for most healthy horses.

Hay and Grass (The Non-Negotiable Base)

Forage should make up at least 50 percent of a horse’s total diet on a dry matter basis, and current recommendations call for 1.5 to 2 percent of body weight per day, per the Merck Veterinary Manual. Common types include:

• Timothy hay: A moderate protein, high fiber grass hay favored for its palatability
• Alfalfa hay: Higher in protein and calcium, often fed to growing or working horses
• Orchard grass: A soft, leafy grass hay many horses find especially tasty
• Fresh pasture grass: The gold standard when available and safe from overgrazing

Grain and Concentrates

Not every horse needs grain. Horses in light work or at maintenance often do fine on forage alone. But performance horses, growing foals, and hard keepers often need concentrated calories from:

• Oats
• Barley
• Corn (in controlled amounts)
• Commercial pelleted or textured feeds formulated for specific life stages

Oklahoma State University Extension notes that grain meals should generally be limited to about 0.5 percent of body weight per feeding, roughly 6 pounds for a 1,200 pound horse, to avoid overloading the hindgut with starch.

Salt and Mineral Supplements

A plain salt block or loose salt should be available at all times. Horses can lose significant sodium through sweat, and a mineral deficiency shows up fast in coat quality and energy levels.

What Do Horses Eat and Drink?

Feeding is only half the equation. Water intake is just as critical, and it is one of the most overlooked parts of equine care.

A typical 1,000 pound horse drinks between 5 and 12 gallons of water per day, according to Kentucky Equine Research, with that number climbing to 15 to 20+ gallons during hot weather, heavy exercise, or lactation. A horse eating dry hay needs noticeably more water than one grazing moisture-rich pasture, since pasture grass can be up to 70 to 80 percent water on its own.

Here is a fact that surprises a lot of new owners: horses can survive around three to four weeks without food, but only three to six days without water. Water is not a side note. It is the single most urgent nutrient on this entire list.

Practical tip from experience: Always keep two water sources available where possible, one plain and one with electrolytes during hot months. I have seen horses refuse an electrolyte bucket entirely if it is their only option, which defeats the purpose. Choice matters.

What Do Horses Like to Eat for Breakfast?

Horses do not eat “breakfast” the way people do, but the first feeding of the day matters enormously for gut health. Because a horse’s stomach produces acid continuously, an empty stomach overnight is one of the leading contributors to gastric ulcers, according to equine veterinary research published through the American Association of Equine Practitioners.

A smart morning routine typically looks like this:

1. Forage first: Hay or pasture access before any grain, ideally available overnight so the stomach is never empty
2. Small grain portion (if needed): Split into a smaller morning meal rather than one large feeding
3. Fresh water check: Buckets or troughs refreshed and checked for ice in winter or algae in summer
4. Salt access: Confirm the salt block or loose salt supply is still available

In my own experience managing a small feeding schedule for boarded horses, the ones on a strict “hay before grain, always” morning routine had noticeably calmer temperaments and fewer digestive complaints than horses fed grain on an empty stomach.

Do Horses Eat Vegetables?

Yes, and many horses genuinely enjoy them as occasional treats. Vegetables are not a replacement for forage, but they add variety, hydration, and enrichment.

Vegetables horses typically enjoy (in moderation):

• Carrots (cut lengthwise to reduce choking risk)
• Celery
• Pumpkin (seasonal favorite, seeds and flesh)
• Squash
• Cucumber

Fruits horses often love:

• Apples (cored, sliced)
• Bananas (peel included, surprisingly popular)
• Watermelon (rind and flesh)
• Strawberries in small amounts

Treats like these should stay under roughly 10 percent of total daily caloric intake to avoid disrupting the fiber-first balance of the diet. Rutgers Equine Science Center notes that most fruits and vegetables are safe for horses in quantities under 2 to 4 ounces per day when introduced gradually.

What Can Horses Eat and Not Eat?

This is where good intentions can go badly wrong. Horses have a genuinely delicate hindgut, and certain foods that are harmless to humans or even dogs can be dangerous or fatal to horses.

Safe Foods and Treats

• Apples, carrots, celery, bananas
• Watermelon, pumpkin, squash
• Plain, unsweetened cereal in tiny amounts
• Sugar cubes and peppermints occasionally (in moderation for horses without metabolic concerns)

Foods Horses Should Never Eat

According to veterinary sources including Rutgers Equine Science Center and multiple equine nutrition specialists, the following should always be avoided:

• Chocolate and cocoa products: Contain theobromine, which horses cannot metabolize and which can cause an irregular heartbeat, colic, or seizures
• Avocado: The fruit, pit, skin, and leaves contain persin, a compound linked to colic, respiratory distress, and heart damage
• Onions and garlic: Can damage red blood cells and cause a form of anemia, even in cooked or powdered form
• Tomatoes and potatoes: Nightshade family plants containing solanine, which can trigger colic and digestive upset
• Caffeine (coffee, tea, energy drinks): A stimulant that can cause restlessness, rapid heart rate, and dehydration
• Dairy products: Horses lack the enzymes to properly digest lactose, leading to diarrhea and gastric upset
• Bread and yeasted baked goods: Can ferment in the gut and contribute to gas and colic
• Rhubarb leaves: Contain oxalates toxic to the kidneys
• Lawn clippings: Ferment rapidly once cut and are a well-documented cause of colic and laminitis

A rule of thumb I have carried into every barn I have worked around: if you would not recognize the ingredient list on a food label, do not offer it to a horse. When in doubt, plain, whole, unprocessed foods are always the safer choice.

Actionable Tips for Feeding Your Horse Well

• Feed by weight, not by scoop. Weigh a flake of hay and a scoop of grain at least once so you know the actual pounds you are feeding, not an estimate.
• Split grain into multiple small meals rather than one large feeding to protect the hindgut from starch overload.
• Never make sudden feed changes. Introduce any new hay, grain, or treat gradually over 7 to 10 days to avoid colic.
• Keep a consistent schedule. Horses thrive on routine, and irregular feeding times are linked to higher stress and ulcer risk.
• Check pastures for toxic plants regularly, including oak seedlings, red maple leaves, and wild cherry, especially after storms when branches fall into paddocks.
• Always introduce new treats one at a time so you can spot a reaction quickly if one occurs.
