丁酸调控幼龄反刍动物瘤胃上皮发育研究进展

瘤胃是反刍动物营养物质消化吸收和代谢的重要器官,其发育状态直接影响反刍动物生产性能和健康。初生犊牛和羔羊,瘤胃功能尚未发育完全,不能够充分消化和吸收固体饲料。因此,在幼龄时期,通过营养调控手段促进反刍动物的瘤胃发育对维持动物健康及提高生产性能具有重要意义。丁酸是瘤胃微生物降解植物性饲料的主要产物,也是瘤胃上皮及宿主的重要能量来源。丁酸调控幼龄反刍动物瘤胃上皮发育是一个历久弥新的话题。主要介绍了幼龄反刍动物瘤胃上皮形态及功能的发育以及丁酸调控幼龄反刍动物瘤胃上皮发育的研究进展。

Research Progress of Butyrate Regulating Rumen Epithelial Development in Young Ruminants

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.
