Check Your Answers
1. False
While girthiness, mood swings, and decreased performance are often attributed to ulcers, they are not definitive signs and may be caused by other factors such as saddle fit, training stress, or dental issues. A confirmed ulcer diagnosis requires a gastroscopy.
2. C. 50% or more
Gastric ulcers are highly prevalent, particularly in performance horses subjected to stress, confinement, and travel. Research indicates that over 50% of horses will develop ulcers at some point in their lives.
3. B. Free-choice access to forage
Horses naturally graze throughout the day, which helps maintain stomach acid balance. Constant availability of hay or pasture assists in reducing acid production and supporting gut health, especially in horses prone to ulcers.
4. False
A fecal test is not a reliable method for diagnosing gastric ulcers and can yield false positives due to other conditions like colitis. The most accurate diagnostic tool is a gastroscopy, where a veterinarian uses a camera to examine the stomach lining.
5. C. Omeprazole plus management changes
The most effective approach to treating gastric ulcers involves omeprazole treatment (prescribed by a vet) along with dietary and lifestyle adjustments such as increasing forage, reducing stress, limiting NSAID usage, and providing frequent meals. This comprehensive strategy addresses both the underlying causes and symptoms of ulcers for long-term gut health.
