氧化应激对猪肠道损伤机制的研究进展

Research Progress of Oxidative Stress on Mechanism of Intestinal Damage in Pigs

畜牧业生产过程中出现的种畜繁殖障碍、幼畜成活率低和发病率高、畜产品品质下降等都与氧化应激有关,氧化应激已经成为动物健康与营养研究的热点。本文对肠道氧自由基产生来源、氧化应激影响肠上皮细胞增殖分化机制及猪生产中氧化应激对肠道氧化损伤进行了综述。

In the process of animal husbandry production,reproductive failure,lowsurvival rate and high incidence of young animals,and the decline in quality of animal products are all related to oxidation stress. Oxidative stress has become a hot topic in animal health and nutrition research. This article reviewed the source of oxygen free radicals in gut,the mechanism of intestinal epithelial cell proliferation and differentiation induced by oxygen free radicals and oxidative stress in pig production.
