Why does my pony eat hay but not grain?

This often indicates dental pain since hay is softer to chew than hard grain. However, it could also be due to gastric ulcers (grain increases acid) or a sudden feed change. Check for quidding (dropping food) and consult your vet for a dental exam and/or gastroscopy.

Can I switch my pony to a completely forage-only diet?

Maybe, but only if your pony maintains healthy weight and energy on high-quality hay or pasture. Grains provide concentrated energy, so athletic or underweight ponies may need them. Always transition slowly to avoid digestive upset, and work with an equine nutritionist if needed.

How long can a pony go without eating grain?

If he is still eating hay and drinking water, a day or two without grain might not be an emergency. But grain is essential for calories and nutrients. If the refusal exceeds 24 hours, or if he stops eating hay, call your vet immediately.

What should I do if my pony is refusing grain after a dental float?

It's normal for a pony to have a sore mouth for 24-48 hours after teeth floating. Offer soaked hay, wet mashes (beet pulp, hay pellets), and soft feeds. Avoid hard grain until he chews comfortably. If refusal lasts longer than 2 days, check for mouth ulcers or sharp edges left behind.

Why is my pony not eating his grain

Why your pony refuses his grain

If your pony suddenly turns up his nose at his grain, it’s a clear signal something is off. The first step is to rule out medical causes: dental problems (sharp points, loose teeth, or ulcers) are the most common reason horses stop eating hard feed. Next, consider changes in feed – even small formula updates can alter taste. Stress (new herdmates, travel, or training intensity) can suppress appetite, and mold or spoilage in the bucket can make grain unpalatable. Always check that his water source is clean and accessible, as dehydration reduces feed intake. If none of these apply and your pony remains off feed for more than 24 hours, contact your veterinarian for a full health check.

Common Physical Reasons

Dental Issues

Horses’ teeth grow continuously, and sharp enamel points often develop, especially on the cheek teeth (premolars and molars). These points can cut the tongue or cheeks, making chewing painful. Signs: dropping grain (quidding), head shaking while eating, or slobbering. A routine dental float (filing) every 6-12 months by an equine dentist or vet can prevent this. Also check for loose or broken teeth, oral ulcers, or gum infections.

Digestive Upset

Gastric ulcers are widespread in performance horses and ponies. Stress, high-grain diets, and intermittent feeding contribute. Ulcers can cause inappetence specifically for grain because concentrated feeds increase stomach acid. Signs: lying down more, teeth grinding, or colic after meals. Your vet can diagnose via gastroscopy and recommend treatment (e.g., omeprazole) and dietary changes (free-choice hay, smaller grain meals).

Pain or Illness

Any systemic disease – from upper respiratory infections to laminitis – can curb appetite. Check for fever (rectal temperature over 101.5°F), nasal discharge, lethargy, or lameness. Also consider muscle soreness or back pain if your pony avoids lowering his head to eat.

Environmental and Feed Factors

Feed Palatability and Freshness

Horses are sensitive to taste and smell. Old, stale, or musty grain may be rejected. Store grain in a cool, dry place in sealed containers. If you recently switched brands or formulas, mix the old and new feed gradually over 7-10 days. Some ponies dislike certain textures (pellets vs. textured feed) or flavors (molasses vs. sweet feed). Adding a small amount of soaked beet pulp or hay pellets can make grain more enticing. Never add excessive sugar or molasses – it can cause insulin spikes and colic.

Water and Salt Availability

Dehydration dramatically reduces appetite. Ensure fresh, clean water is always available, especially if grain is the only moisture source (dry pellets expand in the stomach). A salt/ mineral block encourages drinking. In cold weather, water may be too cold; use heated buckets.

Meal Routine and Competition

Ponies are creatures of habit. A sudden change in feeding time (e.g., breakfast at 7 a.m. instead of 6 a.m.) can cause refusal. Also, if fed in a group, a dominant pony might intimidate yours. Feed in separate stalls or use semi-circle feeders to reduce bullying.

Encouraging Your Pony to Eat

Warm the grain – slightly warmed (not hot) water mixed into the meal can release aroma.
Soak pellets – dry pellets can be hard to chew; add warm water and let them soften into a mash.
Top-dress with flavor – a tablespoon of plain applesauce, unsweetened pumpkin, or electrolyte powder (vet-approved) can entice.
Hand-feed a small portion to reassure and build trust.
Offer hay first – sometimes a pony skips grain because he’s too full on hay. Limit hay 30 minutes before grain.

Never force-feed or leave grain out all day; it spoils and attracts pests. If your pony hasn’t eaten any grain for 48 hours, or shows other symptoms (weight loss, colic, fever), call your vet.

When to Call the Veterinarian

Seek professional advice if your pony:
– Has not eaten any grain for over 24 hours
– Shows signs of colic (pawing, rolling, looking at belly)
– Has a fever, nasal discharge, or cough
– Is losing weight or condition
– Has a history of laminitis or metabolic issues
– Quids (drops partially chewed food) or drools excessively

Your vet can perform a thorough exam, including dental check, abdominal auscultation, bloodwork, and possibly gastroscopy. Early intervention often resolves the issue quickly.

Preventative Tips

Schedule dental exams annually.
Gradually transition feed changes over 7-10 days.
Maintain consistent feeding times and low-stress environment.
Store grain in rodent-proof, dry bins.
Monitor water intake and keep buckets clean.

By addressing both medical and management factors, you can get your pony back to finishing his grain in no time.

Key Takeaway

A pony refusing grain is often due to dental pain, but also consider feed changes, stress, or illness; if he stops eating entirely for more than 24 hours, call your veterinarian.
