摘　　要：蛋白质饲料资源紧缺制约着畜牧业的可持续发展,低蛋白日粮技术可缓解蛋白质饲料资源供给紧张的情况。在保证猪正常生理机能前提下,尽可能降低饲料中蛋白原料的占比,并提高饲料利用率,从而促进畜牧业的绿色可持续发展。肠道微生物的组成及多样性对维持宿主肠道内环境稳态至关重要,日粮蛋白质水平是影响猪肠道微生物的重要因素。文章介绍了低蛋白日粮的概念、配制要求及该技术在畜牧生产中的优势,综述了低蛋白日粮对不同生长阶段的猪肠道微生物影响的研究进展,讨论了低蛋白日粮在猪生产中的重要性,为生猪健康养殖提供参考。The shortage of protein resources restricts the sustainable development of animal husbandry,and low-protein diet technology can alleviate the tight supply of protein feed resources.Under the premise of ensuring the normal physiological functions of pigs,it is possible to reduce the proportion of feed protein raw materials as much as possible,and improving the utilization rate of feed,so as to promote the green and sustainable development of animal husbandry.The composition and diversity of intestinal microbes are crucial for maintaining the homeostasis of the host intestinal environment,and dietary protein level is an important factor affecting the intestinal microbes of pigs.The article reviews the concept,formulation requirements and advantages of low-protein diets,and the research progress on the effects of low-protein diets on the intestinal microbes of pigs at different growth stages is reviewed,aiming to clarify the importance of low-protein diets in pig production and to provide a reference for healthy pig breeding.
