Abstract: The ruminal and intestinal microorganisms in ruminants are in a complex microecosystem, and their diversity and nutritional metabolism are closely related to various factors in this system. Understanding the diversity variations and nutritional metabolism mechanisms of ruminal and intestinal microorganisms in ruminants is an important basis for improving animal welfare, animal production efficiency and animal product quality as well as reducing greenhouse gas emissions by human intervention. The relationship between diversity and nutritional metabolism of ruminal and intestinal microorganisms in ruminants and the individual environmental factor has been extensively studied and some advances have been achieved, which plays a certain role in guiding production practice and protecting the environment. This paper reviews the research advances on diversity of ruminal and intestinal microorganisms in ruminants in China and abroad in recent years, as well as interactions and corresponding mechanisms between microorganisms and host animals, diet structures and environmental factors, in hoping to provide references for exploring the roles and mechanisms of ruminal and intestinal microorganisms in nutritional metabolism in ruminants.

Key words: ruminants, multi-omics, rumen, intestinal tract, microorganisms, nutritional metabolism
