Abstract: Rumen,a very important and specific organ in ruminants,is responsible for feed digestion,nutrient absorption and metabolism,thus its developmental state directly affects animal performance and health. The rumen of newborn calves and lambs has not been well developed,thus it is unable for them to fully digest and absorb solid feed. Therefore,the promotion in rumen development of ruminants through nutritional strategies is vital to maintain animal health and improve production performance. Butyrate,the main end product of rumen microbial fermentation of plant feed,is also the important energy source of rumen epithelia and host. The topic of butyrate regulating rumen epithelial development has lost none of its original charm. This paper mainly introduces the development of rumen epithelial morphology and function and the research progress of butyrate regulating rumen epithelial development in young ruminants.

Key words: butyrate, volatile fatty acids, rumen epithelium, young ruminant
