Influence of Controlled Ambient Temperatures and Diets on the Incidence of Esophagogastric Ulcers in Swine2

Abstract
Esophagogastric ulcers and associated lesions in swine were increased significantly (P< .01) by fluctuation by ambient temperatures as compared to constant temperatures or an expanded corn diet as compared to a raw corn diet. The stomach contents of those animals afflicted with esophagogastric ulcer contained significantly (P .01) more fluid than animals with normal stomachs. A significant (P .01) cyclic pattern was observed in plasma ascorbic acid levels; however, there was no statistically significant change in plasma ascorbic acid associated with the development of esophagogastric ulcers.
