益生菌对奶牛产奶量、乳成分及瘤胃微生物区系的影响

优质牛奶的充足供给需要以奶牛的健康养殖为基础。益生菌在奶牛饲料中的添加对奶牛的产奶量、乳成分和瘤胃微生态区系均有正面影响,可以通过增加奶牛瘤胃中有益微生物的含量,同时竞争性抑制有害菌的生长定殖,进而提高奶牛的机体健康状况和生产性能。本文对益生菌的功能、作用机制及在奶牛养殖中的应用效果进行阐述,旨在为益生菌的广泛应用提供参考。

Effect of Probiotics on Milk Yield,Milk Composition and Rumenmicrobiota of Dairy Cows

Adequate supply of high quality milk needs to be based on the healthy breeding of dairy cows.The addition of probiotics to dairy cattle feed has a positive effect on milk yield,nutrient composition of milk and the microecological environment of the rumen,which can increase the content of beneficial microorganisms in the rumen of dairy cows while competitively inhibiting the growth and colonization of harmful bacteria,thereby improving the health status and performance of dairy cows. In this paper,the functions, mechanisms of action and effects of probiotics in dairy farming were described with the aim of providing a reference for the wide application of probiotics.
