| Abstract: | The study was divided into two groups to investigate the effect of adding silage on the weight gain of beef cattle, group Ⅰ（experiment）and group Ⅱ（control）. The results showed that there was significant difference between two groups in aver- age daily gain of the period of beef cattle fattening,and the group I has increased 104.8g compared with group II （P〈0.05）, the feed conversion ratio （FCR）, ME, and DCP, the group I have respectively reduced 14.2 %, 9.5%, and 9.8 % compare with the group Ⅱ （P〈0.05）, feed intake increased 25 %, beef yield increased 9.4 kg,income increased 108 Yuan compare with the group Ⅱ. |
