有机铬在断奶仔猪生产中应用的研究进展

Research Progress on Application of Organic Chromium Preparations in Diets of Weaning Piglets

铬是动物机体必需的微量元素之一,近年来,国内外营养学家展开了大量的研究,尤其在断奶仔猪饲养方面,应用效果较好。作者对有机铬在动物体内吸收、运输及排泄的特点,以及参与糖、脂类及含氮物质代谢的生物学功能进行了介绍;并就其对断奶仔猪生长性能、抗腹泻和免疫功能等方面的影响,以及在断奶仔猪养殖中的应用前景作一综述。

Chromium is an essential trace element for animals.In recent years,domestic and foreign nutritionists have started a lot of research,especially in weaned piglets feeding areas,and have made a lot of money results.In this paper,organic chromium absorption,transport and excretion characteristics in vivo,and the biological function of organic chromium,including the glucose metabolism,lipid metabolism and nitrogen metabolism were recommended,and then introduced the effects of growth performance,anti-diarrhea,immune function and other aspects of in the feeding of piglets weaned pigs,as well as application prospect of in weaned piglets were summarized.
