金属硫蛋白在动物营养学上的应用

The Application of Metallothionein in Animal Nutrition

综述了金属硫蛋白(MT)在动物的健康、疾病以及生长性能等方面的重要作用。MT能参与畜禽体内微量元素Cu、Zn等的代谢,可利用MT来评价动物机体Zn的营养状态;MT具有抗应激的作用;MT有重金属解毒作用,在高铜、高锌日粮的促生长机理中发挥重要作用;MT促进动物机体生长发育;此外,MT在Se对动物机体的各种生理作用中发挥重要作用。

Metallothionein(MT) have important functions on health, disease and growth capability of animals. There are 6 aspects which are summarized: MT participate in metabolizing on microelement which are Cu, Zn,et al. Utilizing MT estimates the Zn of nutritional states, MT has the function of resisting spurring, MT has the detoxification effect on being dead against heavy metal that could exert important function on promoting growth mechanism for the animal of diet with high Cu and Zn, MT can accelerate the growth and development of animal economy. Moreover, MT exerts important function on most physiological effects of Se on bodies.
