摘　　要：随机选择22~24月龄、体重400kg左右的西门塔尔杂交公牛共20头,互为对照,试验期160d。试验组使用TMR日粮饲喂育肥牛,头均日增重1.31kg,料重比6.21:1;对照组采用常规喂法头均日增重1.12kg,料重比7.27:1。试验组较对照组日增重提高16.96%,料重比降低17.1%,两组差异显著(P<0.05)。A total of 20 simmental hybrid bulls, aged 22-24 monthsand weighed 400 kg, were randomly selected for control.The trial period was160 days.TMR diet wasused to feed fattening cattle in the experimental group, with the average daily gain of 1.31kg and feed conversion ratio of 6.21:1 for each bull.The average daily gain of the control group was1.12kg by conventional feeding, and the feed conversion ratio was7.27:1.Compared with the control group, the daily gain of the experimental group increased by 16.96%, and the feed conversion ratio decreased by 17.1%.The difference between the two groupswassignificant ( P <0.05).
