摘　　要：在肉牛育肥期,通过饲喂添加秸秆发酵剂的青贮玉米秸秆饲料,Ⅰ组(试验组)的日增重比Ⅱ组(对照组)高104.8g,增长率为10%,经t检验差异显著(P<0.05);Ⅰ组比Ⅱ组每增重1kg所消耗的精料、ME、DCP都有大幅度的下降,分别降低14.2%、9.5%、9.8%,经t检验差异显著(P<0.05);Ⅰ组比Ⅱ组青贮饲料采食量增加25%;Ⅰ组比Ⅱ组肉牛头均可多产肉9.4kg,头均增加收入108元。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.
