[Objective] To explore the effects of Chinese herbal compound preparations on the production performance,milk quality and serum indicators of dairy cows. [Method] The 50 Chinese Holstein cows from a dairy farm in Liangshan,Sichuan Province were selected as experimental animals and divided into two groups. Each group was set up with 5 replicates,and each containing 5 cows.Cows fed with a regular basic diet were used as the control group,while cows fed with an additional 0.1% concentration of Chinese herbal compound preparation were added to the basic diet as the experimental group.The entire research experiment period is 60 days. [Result] The average daily milk production and milk protein rate of the experimental group were significantly higher than those of the control group（P<0.05）,while the feed to milk ratio and the number of milk somatic cells were significantly lower than those of the control group（P<0.05）.The serum indicators such as AST,ALT,and NEFA in the experimental group were significantly lower than those in the control group（P<0.05）.The contents of GLU,BUN,ALB,TP,etc.in serum were not significantly different between the two groups（P>0.05）. [Conclusion] Adding Chinese herbal compound preparations to dairy cow diets can significantly improve their production performance,improve milk quality,and promote the healthy growth.It is worth promoting and applying in the future.
