There are many possible reasons why horses develop gastric ulcers, writes David Ramey, DVM. He says most of them are related to how people manage their horses. Diet, confinement and medication are three areas where horse management may induce ulcers.
The most thoroughly tested ulcer treatment is omeprazole, which is absorbed into the small intestine and works systemically by inhibiting stomach acid secretion. Antibiotics are not usually indicated because bacteria have not been shown to cause gastric ulcers in horses like they do in humans.
