What Every New Horse Owner Should Know About Ulcer Prevention

What can new horse owners do from the beginning to reduce the risk of stomach ulcers? Stomach ulcer prevention is an important part of horse management, particularly when establishing feeding, turnout, and training routines. Fortunately, prevention does not have to be complicated. A few consistent management choices can help reduce factors associated with ulcer development.

Understanding these habits early makes it easier to build a routine that supports your horse’s digestive health and helps prevent avoidable problems later.

Why This Matters So Much for a New Horse Owner

Gastric ulcers are remarkably common in horses, and the underlying cause comes down to basic equine biology. A horse’s stomach continuously produces acid, regardless of whether the horse is actively eating, which means long gaps between meals leave the stomach lining genuinely exposed.

According to a peer-reviewed review published in the journal Animals, veterinary researchers recommend that horses consume at least 2% of their body weight per day in good-quality roughage as one of the most effective, well-supported management strategies for reducing ulcer risk.

That’s a genuinely useful, concrete number for a new owner to work with, since it turns a vague piece of advice like “feed plenty of hay” into something you can actually measure and plan around.

The Feeding Habits That Matter Most

A handful of feeding-related choices make the biggest difference in ulcer prevention:

• Frequent, small meals rather than two large ones — long gaps between feedings leave the stomach empty and acidic for extended periods
• Free-choice or near-continuous forage access — horses are natural grazers, and consistent access to hay or pasture keeps the stomach buffered throughout the day
• Limiting high-grain diets — grain moves through the stomach quickly and produces less saliva than forage, both of which increase ulcer risk
• Never exercising on an empty stomach — a small amount of hay before riding helps protect the stomach lining during exercise
• Consistent, clean water access — dehydration and reduced water intake are both linked to higher ulcer risk

None of these require anything exotic, they’re simply about structuring a feeding routine around how a horse’s digestive system actually works, rather than around human convenience.

Why Stress Management Deserves Just as Much Attention

Stress is an important factor in ulcer development, and it does not always appear dramatic. Stall confinement, frequent travel, changes in routine, and limited social contact can all increase stress and potentially raise ulcer risk, even when feeding is otherwise well managed.

For practical guidance, ulcer prevention covers several management strategies that can help reduce these risks. Mad Barn also highlights the importance of turnout, social interaction, consistent routines, and appropriate feeding as part of a broader approach to supporting gastric health.

Getting Turnout and Socialization Right

Horses are herd animals, and isolation is a genuine stressor that new owners sometimes overlook, especially when managing a single horse or a small setup. Where possible, allowing your horse to see and interact with other horses, even just visually across a fence line, helps reduce the kind of chronic stress that contributes to ulcer development.

Increasing turnout time, rather than relying heavily on stall confinement, gives a horse more natural grazing opportunities and more of the movement and social contact that supports genuine wellbeing.

Watching for Early Warning Signs

Even with good prevention practices, it is important to notice subtle changes in your horse. Watch for:

• Poor or inconsistent appetite
• Mild, recurring colic
• Girthiness or sensitivity
• Changes in behavior or performance

Because many affected horses show few obvious symptoms, consistent observation and proactive care are important. Small changes are easier to address when they are noticed early rather than ignored.

Building These Habits Into Your Routine From Day One

The easiest time to build good ulcer-prevention habits is right at the start, before less ideal patterns become the default. Consistent access to forage, regular turnout, and a predictable daily routine can all support better digestive health.

It is also worth planning ahead for situations that may disrupt that routine. Travel, competitions, boarding changes, or periods of stall confinement can increase stress and alter normal feeding patterns. Making gradual adjustments where possible can help your horse adapt more comfortably.

New owners who treat these management choices as part of everyday care, rather than optional extras, can create a more consistent environment that supports long-term digestive health.

Conclusion

Ulcer prevention doesn’t require anything complicated, it comes down to understanding how a horse’s stomach actually works and building a routine around that reality from the very beginning. Frequent forage access, limiting long fasting periods, minimizing unnecessary stress, and maintaining social contact with other horses are all genuinely achievable steps for any new owner, regardless of experience level.

Given how common gastric ulcers are and how quietly they can develop, starting with strong prevention habits from day one is one of the most valuable things a new horse owner can do for their horse’s long-term comfort and health.
