直接饲喂微生物在奶牛生产中的研究进展

Research Advance of Direct-fed Microbial on Dairy Cow's Production

直接饲喂微生物(direct-fed microbial,DFM),亦称"益生菌",被认为是目前较好的抗生素替代品。本文就DFM作用机理和对奶牛的生产性能的影响作了论述,并就今后的发展趋势作了探讨。

Direct-fed microbial（DFM）,also called ＂probiotics＂,it is commonly believed that it is a good substitute for antibiotics.This paper discusses the mechanism of DFM.Meanwhile,the influence on the performance of the dairy milk production is involved,and the development prospects were discussed.
