Research from the College of Veterinary Medicine at the University of Florida, reported in the Journal of Veterinary Internal Medicine, found that feeding small amounts of corn oil reduces stomach acid and increases the level of protective prostaglandins, PG E2.
Healthy ponies were fitted with cannulas in their stomachs to allow direct measurement of fluid. They were accustomed to a hay-only diet, and differences in stomach pH and PG E2 wer measured both with and without 45 cc (about 1.5 oz.) of corn oil added to the diet. This suggests that adding a little corn oil helps protect horses prone to gastric ulcers. For a full-size horse, the amount should be increased to 3 oz./day.
