摘  要:
A total of 20 Simmental hybrid bulls, aged 22-24 months and weighed 400 kg, were randomly selected for control. The trial period was 160 days. TMR diet was used to feed fattening cattle in the experimental group, with the average daily gain of 1.31 kg and feed conversion ratio of 6.21:1 for each bull. The average daily gain of the control group was 1.12 kg by conventional feeding, and the feed conversion ratio was 7.27:1. 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 groups was significant(P<0.05).
