Horse Gastric Ulcer Prevention

Equine gastric ulcer syndrome (EGUS) affects the majority of performance horses and many leisure horses, with management and feeding practices being key prevention factors.

Key Facts

EGUS affects around 70-90% of racehorses and 50-60% of performance horses
Gastric acid secretion continues continuously in horses but saliva production requires chewing forage
Periods without forage access cause acid accumulation and ulceration
Omeprazole is the most effective treatment but management change prevents recurrence
Lifestyle factors including 24-hour forage access and reduced stress significantly reduce ulcer risk

Welfare Considerations

Equine gastric ulcer welfare requires fundamental management changes including ad libitum forage access, reduced stabling time, and minimised transportation and training stress. Treatment without management change results in recurrence. The prevalence of EGUS in performance horses reflects welfare compromise in pursuit of competition success.

What You Can Do

Ensure horses have ad libitum forage access to prevent gastric acid accumulation
Monitor for ulcer symptoms and seek veterinary diagnosis before treatment
Advocate for competition management practices that prioritise equine welfare
