Abstract

Abstract: Microbial colonization in the digestive tract in early life can affect the animal body and have long-term health effects. A detailed understanding of the colonization of early rumen microorganisms is of great significance to animal health, growth and development. After birth, ruminants begin to contact with external microorganisms, and their rumen microbial flora structure changes dramatically, which is easily affected by animal age, species and dietary structure. Rumen contains complex microbial flora, which is mainly composed of anaerobic bacteria, archaea, fungi and protozoa. The present article reviews the colonization composition and changes of rumen bacteria, archaea, fungi and protozoa in young ruminants, and expounds the effects of feed composition and feed additives on the rumen microbiota of young ruminants, so as to provide a theoretical basis for the phased nutritional regulation of young ruminants.

Key words: young ruminants, microbial colonization, diet, nutrition regulation, feed additive
