摘　　要：确定蛋鸡精准营养需要,对现有饲料资源高效合理利用,是解决我国饲料资源短缺问题的有效途径之一。随着品种选育和营养调控策略的不断进步及饲养环境和饲粮原料组成出现的差异,现代品种蛋鸡对蛋白质和氨基酸的营养需要不断发生变化。文章综述了近5年蛋鸡蛋白质和氨基酸营养需要量的测定方法、蛋白质和氨基酸营养需要量及低蛋白质饲粮配方下蛋白质和氨基酸营养需要量的最新研究成果,旨在为更精准配制蛋鸡日粮、促进我国蛋鸡养殖业的健康发展提供依据。To determine the precise nutritional requirements of livestock and poultry and to make reason⁃able and efficient utilization of existing feed resources is an effective way to solve the problem of short⁃age of feed resources in China.With the continuous progress of breeding and nutrition regulation strate⁃gies,as well as the differences in feeding environment and diet composition,the nutritional requirements of modern laying hens for protein and amino acids are constantly changing.This paper reviewed the lat⁃est research results on the determination methods of protein and amino acid nutritional requirements of laying hens,the nutritional requirements of protein and amino acids and the nutritional requirements of protein and amino acids in low-protein diets in recent 5 years,aiming to provide a basis for more accu⁃rate formulation of laying hen diet and promoting the healthy development of laying hen breeding indus⁃try in China.
