摘　　要：反刍动物肠道内存在多种微生物,它们与机体之间互相依存,构成了一个动态的平衡体,对宿主的营养吸收、代谢和免疫系统的发育均有影响。反刍动物的肠道微生物主要来源于幼龄时期的定植,并且逐渐发育成复杂的微生物群落。因此,探究幼龄反刍动物的肠道微生物定植对于提高反刍动物的存活率和生长质量具有积极影响。本文总结了幼龄反刍动物肠道微生物定植规律,并介绍了一些调控手段。但这些调控手段最佳实施的时间,以及具体的关键性微生物还需要进一步研究。A variety of microorganisms exist in the intestinal tract of ruminants,which are interdependent with the organism and constitute a dynamic equilibrium that has an impact on the host’s nutrient absorption,metabolism and immune system development.The intestinal microorganisms of ruminants mainly originate from colonization at a young age and gradually develop into a complex microbial community.Therefore,exploring the intestinal microbial colonization of young ruminants has a positive impact on improving the survival rate and growth quality of ruminants.In this review,patterns of gut microbial colonization in young ruminants were summerized and some regulatory tools were introduced.However,the optimal time of implementation of these regulatory tools and the specific key microorganisms need to be further researched.
