锌在蛋鸡生产中的研究进展

Research Progress on Zinc in Laying Hens Production

锌作为机体生命活动不可或缺的微量元素,参与蛋鸡物质代谢、免疫功能、抗氧化功能以及基因、激素调控等生理机能,维持内环境稳态,并影响产蛋性能与蛋品质。随着日粮锌的研究不断拓展与深化,其在蛋鸡生产中的作用与影响也越显突出。论文归纳介绍常见种类锌制剂,并对锌在蛋鸡生产中的应用进行简要综述。

Zinc, an indispensable microelement in life, is involved in substance metabolism, immunity,antioxidant function, gene and hormone metabolism of layers. It also affects layers’ homeostasis, egg performance and quality. With the study on zinc in diet deepening, it plays an increasingly important role in growing layer. In this paper, common zinc preparation and their biological function were briefly introduced, and how it can be used for growing layers was also briefly reviewed.
