Abstract

Abstract: Ruminants are important livestock in animal husbandry.It is of great significance to study the colonization process of rumen microorganisms in young ruminants,and take scientific early regulation measures by utilizing the colonization rules so as to improve the production efficiency and product quality of ruminants,and to maintain the high efficiency,health and sustainable development of animal husbandry.The colonization process of rumen microbes is accompanied by huge changes in the rumen development and diet of young ruminants.When young ruminants are breastfeeding,the rumen does not work due to the presence of the esophageal groove reflex,so the development is slow.At this time,only few functional microbes gradually colonized.As the age increases,young ruminants take in large amount of solid feed,the rumen develops rapidly and matures under the stimulation of solid feed.At this time,a large number of bacteria colonized,rumen fermentation is gradually active,the dominant microbial have changed greatly compared with the previous period,and the accumulation of rumen fermentation products further stimulated the development of rumen.Ruminants have experienced a physiological transition from non-rumination to rumination at the young stage.The stage before rumination is the period of the most sensitive and easy to intervene.It is possible to take artificial regulation measures for ruminant rumen microbes at the young stage to ensure the healthy and growth.In this paper,the early development of rumen,the types and sources of rumen microorganisms and their colonization in the rumen of young ruminants were reviewed.The important functions of rumen microorganisms in rumen digestion and metabolism,production performance and animal health were elucidated.The commonly used rumen microbial control techniques were also included,so as to provide a reference for the feeding management and nutrition regulation of young ruminants in the production system.

Key words: ruminant; rumen microorganisms; colonization process; atificial regulation
