钴在动物营养中的研究进展

Research Progress of Cobalt in Animal Nutrition

微量元素钴是构成动物体内辅酶、活性蛋白、维生素等的不可或缺的重要成分,对机体的生长和营养代谢有着极其重要的生物学作用。文章就钴的代谢规律,钴在动物中的生物学功能,钴的需要量及钴缺乏与过量的症状及其发病机理等进行综述,旨在精准供给钴营养,实现绿色养殖。

Trace element cobalt is an indispensable and important component of coenzyme,active protein and vitamin in animals,and has an extremely important biological role in the growth and nutrient metabo⁃lism of the body.In this paper,the metabolism of cobalt,the biological function of cobalt in animals,the requirement of cobalt,the symptoms of cobalt deficiency and excess,and their pathogenesis are re⁃viewed.This paper aims to accurately supply cobalt nutrition and actualize green breeding.
