摘要
选择48头月龄体重相近的育肥牛,分别饲喂全株玉米青贮饲喂比例(占粗饲料比例,以干物质计)为30%、48%、50%、70%、90%、100%的全价日粮,研究各试验牛只育肥性能的差异。结果显示,当全株玉米青贮饲喂比例超过70%时,试验牛只发生酸中毒现象;全株玉米青贮的适宜饲喂比例为30%~70%,该饲喂比例下育肥牛的健康情况、日增重、料重比等指标均较好。
The first 48 months of age with similar weight of shelf beef cattle randomly divided into 8 groups, respectively fed whole crop corn silage（add the proportion of the ratio of roughage, dry matter） for 30%, 48%, 50%, 70%, 90% and 100% of full price ration of the test cow produces only performance differences. The results showed that when the proportion of whole crop corn silage added more than 70%, the experimental cows occurs only acid poisoning; whole crop corn silage suitable adding ratio is 30%~70%, the adding proportion of beef cattle health, average daily gain, feed weight ratio and other indicators are better.
