本试验分别用西杂 F2 代母牛 90头和西杂 F3代公牛 30头做产奶和育肥试验 ,每组又分试验组和对照组 ,各组的试验组与对照组精料用量及营养水平相同。试验组饲喂鲁梅克斯 K- 1杂交酸模牧草 ,对照组饲喂青刈杂草。产奶组在一个泌乳期 (2 70 d)内 ,试验组比对照组多产奶 81 8kg/头 (P<0 .0 5) ,增收 1 852 .2元 /头 ,育肥组育肥 90 d内 ,试验组平均日增重比对照组提高 33% (P<0 .0 5) ,增收 1 90 .4元 /头。
Simmental crossbred F\-2 cows and 30 Simmental crossbred F\-3 bulls were assigned for milk production and finishing trail, the milk production and the finishing group was equally divided into control group and test group, respectively.

The results showed that the milk production of the test group was higher than that of the control by 818 kg per cow and increased income for 1852.20 per cow during 270d ; during the finishing period of 90d , the average daily gain of the test group was raised by 33% than that of the control and increased income for 190.40 per cow.
