摘　　要：规模化畜牧业的发展为保障畜产品供应做出了巨大贡献,但当前畜牧业发展面临蛋白饲料资源紧缺和养殖环保压力大的问题。基于理想氨基酸模式的低蛋白日粮技术的应用为解决这些问题提供了可能的途径。文章就低蛋白日粮对蛋鸡生产性能的影响及补充氨基酸的效应,低蛋白日粮下氮代谢及低蛋白日粮对粪污减排和生态环境的影响进行了综述,以期为低蛋白日粮技术在蛋鸡生产中更好地应用提供参考和借鉴。The development of large-scale animal husbandry has made great contributions to ensuring the supply of animal products,but the current development of animal husbandry is facing the problems of protein feed resources shortage and great environmental protection pressure.The application of low protein diets based on ideal amino acid pattern provides a possible way to solve these problems.This pa⁃per reviewed the effects of low-protein diets on the performance of laying hens and the effect of amino acid supplementation,nitrogen metabolism under low-protein diets,and its impact on ma⁃nure emission reduction and the ecological envi⁃ronment,in order to provide reference for the bet⁃ter application of low-protein diet technology in laying hens production.
