Abstract

The effects of temperature and diet on esophagogastric ulcer incidence were studied. Esophagogastric ulcers and associated lesions in swine were increased significantly (P<.01) by fluctuation of 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 were 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.
