The best way to prevent equine ulcers is to mimic the horse’s natural lifestyle: provide free-choice hay or pasture, limit or eliminate grain, maximize turnout with herd companionship, and minimize stress from training, travel, or stalled confinement.
Feed for a Healthy Stomach
Horses evolved to graze nearly 24/7. Their stomachs constantly produce acid, and without a steady buffer of saliva and forage, the delicate squamous lining becomes vulnerable to ulceration. To prevent this, ensure your horse has access to forage at all times , hay, pasture, or a slow feeder works. If you must feed grain, keep meals small (under 2-3 pounds per meal) and consider a hay-based balancer. Many horses thrive on a forage-only diet. Avoid long periods (over 6 hours) without food. For stalled horses, use a hay net to extend eating time.
Manage Turnout and Socialization
Stall confinement is a major risk factor for ulcers. Turnout reduces stress and allows natural grazing behavior. Aim for at least 12 hours of turnout per day, ideally with a buddy. Horses are herd animals; isolation can spike stress hormones and increase ulcer risk. If turnout is limited, use a large paddock or consider a companion such as a goat or pony. Even hand grazing for 30 minutes twice daily can help.
Reduce Stress from Training and Travel
Performance horses face added stress from intense exercise, trailering, and competition. To mitigate, always offer hay before and after work , a full stomach helps buffer acid. During long trailer rides, stop every 2-3 hours to offer hay and water. Avoid exercising on an empty stomach. If your horse is prone to nervousness, consider natural calming supplements (like magnesium or chamomile) after consulting your vet. Keep a consistent daily routine to reduce anxiety.
Avoid Overuse of NSAIDs
Non-steroidal anti-inflammatory drugs (like phenylbutazone or flunixin meglumine) can damage the stomach lining when used long-term or at high doses. Work with your vet to find the lowest effective dose for the shortest duration. If your horse requires frequent NSAIDs, ask about protective options like omeprazole or sucralfate. Never exceed the recommended dose.
Always consult your veterinarian if you suspect your horse has ulcers , symptoms include poor appetite, weight loss, mild colic, or a sour attitude. For high-risk horses (intense training, travel, or confinement), your vet may recommend preventive medication or gastric protective supplements.
Key Takeaway
Provide free-choice forage, limit grain, maximize turnout, and reduce stress to naturally prevent equine ulcers; consult your vet for high-risk horses.
