Abstract: 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.

Key words: young ruminants, gut microorganisms, colonization pattern, nutrition regulation
