3,354 fattening pigs were examined. Gross pathologic alterations of the stomach were classified as normal, with epithelial change, erosion, ulcer and scar formation. In the seasonal prevalence of gastric ulceration, severe ulceration with erosion was shown during autumn and winter, whereas mild ulceration was mainly shown during spring and summer. Of the 3,354 pigs examined, 20.7% were found to be normal. Of the rest, 40% had epithelial changes, followed by erosion (24.7%), ulcer (13.6%) and scar formation (0.9%), respectively. In the prevalence of ulcers in the different regions of the stomach, the fundic region had the highest rate (61.6%) of ulceration, followed by cardiac (21.7%), esophageal (15.0%) and pyloric region (1.7%). The principal gross changes were severe epithelial changes with keratotic proliferation in the esophageal region, and in the fundic region, severe folding of the stomach wall was covered with bloody mucous exudates. Main histopathological changes were inflammatory cell infiltrations in most cases, hemorrhages in acute ulcers and prominent proliferation of granulation tissues in chronic ulcers
