| Abstract: | Objective]This study examined the effect of compound enzyme on the production perform ance in the ration of dairy cattle. Method] Regular feeding and management method was taken. Result] The results showed that the milk yield of experimental group （21.62 kg） was increased 4.19% than that of the control group （20. 75 kg） with diets supplemented with 0. 1% ＂Dolly＂ composite enzyme, and the difference was significant （P〈0. 01）. The average milk fat percentage was higher than that of control group （increased by 3.38%）. The average gross profit per cattle was 23.55 Yuan daily of the experimental group in the trial period, and the control group was 20.43 Yuan daily. The income of experimental group was hi of 0.1 er than that of the control group ＂Tianli＂ on the dairy ration coul per cattle （3.12 Yuan）. Conclusion]Adding composite enzyme d significantly increase the milk age, and improve the economic efficiency of dairy farming. production and milk fat percent |
