The good news is that you can strategically manage his diet to minimize incidence and severity of ulcers.

Researchers at the University of Tennessee and University of Kentucky, studying ponies with cannulas (openings into the digestive tract), were able to sample material in the stomach and colon to learn more about ulcers.

"The initial thrust of early ulcer research was to find drug therapies and acid blockers to help with treatment," says Duren. "But along with medication, we also must consider what we should do from a feeding standpoint to reduce or help heal this condition, or prevent ulcers in the first place.

"Many ulcers occur in performance/racehorses for two reasons," he continues. "First, we change their diet.
