摘　　要：B族维生素是一类水溶性维生素,主要以辅酶或辅助因子的形式参与机体能量代谢。长期以来人们认为反刍动物能够通过瘤胃微生物合成B族维生素来满足生长与生产的需要,但随着研究的深入发现,瘤胃合成的B族维生素难以满足高产动物的需要,外源添加B族维生素在改善反刍动物健康、提高产奶量、改善乳品质、提高机体免疫功能以及改善繁殖功能等方面都能起到积极作用。本文拟对B族维生素的营养生理作用、饲料来源、瘤胃合成及其影响因素进行总结,以期为B族维生素在反刍动物生产中的应用提供参考。Vitamin B is a kind of water-soluble vitamin,as coenzyme or cofactor to participate energy metabolism.It is considered that ruminant through rumen bacteria synthesized to meet the needs of growth and production.However,with the development of the research,the synthesis of vitamin B has been difficult to meet the needs of high yield animals.Exogenous vitamin B plays a positive role in improving ruminant animal health,increasing milk production,improving milk quality,increasing body’s immune function and improving the function of reproduction and so on.In order to provide a reference for the application of vitamin B in ruminant production,this review summarized the nutritional and physiological functions,feed sources,rumen synthesis and its influencing factors of vitamin B.
