摘要
选择改良去势公牛48头,随机分为4组,分别饲喂青贮、微贮、氨化与干玉米秸(对照组),进行70天育肥试验,比较用不同方法处理的玉米秸饲喂肉牛的增重效果。结果表明,青贮组、微贮组与氨化组牛增重高于对照组,差异显著(P<0.05)。但青贮组、微贮组与氨化组之间牛增重差异不显著(P>0.05)。
48 improved crossbred beef cattle were divided randomly into 4 groups to conduct a 70-d fattening trial in order to determine the effect of feeding common corn stalk silage , microbial silage, ammoni- ated silage and dry corn straw（control group） on fattening result, respectively. The results showed that average gain of treatment group were significantly higher than that of control group（P〈0. 05）,but there were not significant difference between three treatment groups for average gain of beef cattle （P〉0.05）.
