Abstract: A feeding trial was conducted to investigate the effects of a compound additive on the production performance of high producing dairy cows. A total of 40 high producing dairy cows with similar age, weight and calving date were divided into 4 groups randomly(n=10)and were assigned to one of the four diets: basal diet or basal diet supplemented with 0.5%,0.8% or 1.0% compound additive, the feeding trial lasted for 45 days, including 10 days of pre-experiment. Feed intake, milk yields, milk compositions (fat, protein, and lactose and s somatic cell count were measured. The results showed that dietary supplementation of the compound additive had no effect on the milk composition, but it could signiifcantly improve the milk yield of dairy cows. With cost considering, the ratio of 0.5% had better effects.
