다국어 초록 (Multilingual Abstract)

It is important and is studying the occurrence date of gastric ulcers in pigs in several Western countries. Gastric ulcers were founded in almost all pigs with only a difference in progress, and usually were occurred on the par esophagea in pigs. Also, it is generally difficult to detect until biological signs and symptoms appear. Many studies have shown that gastric ulcers have a wide variety of causes. Gastric ulcers were influenced by particle size in diets. If the particle size in diets is less than 400 microns, gastric ulcers easily occur. In nutritional aspects, gastric ulcers were influenced by fiber, vitamin E, zinc and melatonin. Many studies showed that when the fiber, zinc, melatonin and vitamin E were added in diet, gastric ulcers in pigs decrease. In feeding management, the elements such as straw and feed restriction affected the gastric ulcers of pigs. All these factors connected with a stress in pigs, and stress results in productions of large amounts of excess acid. Because of excessively producing a gastric acid, gastric ulcers occur. However, many people in Korea are interested in the gastric ulcers of pigs. Therefore, further studies on gastric ulcers of pigs should be conducted and researcher in Korea should try to prevent them in livestock industry.
