We often focus on training programs, conditioning, and tack fit—but one critical factor is frequently overlooked: gastric health. A horse’s stomach is designed for continuous grazing, and modern management practices can disrupt that natural balance, leading to gastric ulcers and decreased performance.
Equine gastric ulcer syndrome (EGUS) is especially common in performance horses due to intermittent feeding schedules, high-grain diets, travel, and stress. Studies suggest that a significant percentage of competition horses experience some degree of gastric irritation. Unfortunately, the signs aren’t always obvious. Subtle changes like reduced appetite, irritability during saddling, weight loss, dull coat, or a drop in performance can all point to underlying gastric discomfort.
Providing consistent access to forage is one of the most effective ways to protect the stomach lining. Hay helps buffer stomach acid and supports natural digestive function. Limiting long periods without feed is essential—horses should ideally not go more than 4–6 hours without forage.
High-starch feeds can increase acid production, so consider incorporating fat-based energy sources or more digestible fiber options. Adding alfalfa hay before exercise may help neutralize stomach acid due to its higher calcium content.
Regular turnout, minimizing abrupt routine changes, and careful travel planning can make a noticeable difference. For horses in heavy work or high-stress environments, preventative supplements or veterinary-prescribed treatments may be warranted.
Routine monitoring is just as important as prevention. Pay attention to behavioral and physical changes, and consult your veterinarian if gastric issues are suspected. Early intervention can prevent more serious complications and keep your horse comfortable and competitive.
