| Abstract: | Twenty-four cows with similar delivering time were divided into 4 groups.The diets in trial groups were added with 0.1%,0.2% and 0.3% compound enzyme respectively,the diet in the control group was not added compound enzyme.The trial lasted 45 days.The results showed that the milk production of the 0.2% addition group increased 3.64 kg/d,2.02 kg/d and 3.89 kg/d compared with control group,0.1% addition group and 0.3% addition group respectively.The differences were extremely significant(P<0.01).The milk prod... |
