[目的]本试验研究了在日粮中添加复合酶制剂对泌奶牛生产性能的影响。[方法]采用奶牛一般饲喂方法,设立对照组和试验组。[结果]表明,在日粮中添加0.1%＂天多利＂奶牛复合酶,试验组（21.62kg）比对照组（20.75kg）提高产奶量4.19%,差异极显著（P〈0.01）;平均乳脂率比对照组提高了3.38%,差异显著（P〈0.05）;试验期间,试验组每头泌乳牛平均每天获毛利23.55元,对照组每头泌乳牛平均每天获毛利20.43元,试验组比对照组每头多盈利3.12元,增收效益明显。[结论]试验表明,奶牛日粮中添加加0.1%＂天多利＂奶牛复合酶,可显著提高奶牛的产奶量和乳脂率,提高奶牛养殖的经济效益。

[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
