对全株玉米青贮混合日粮饲喂肉牛育肥效果进行了试验研究。选择年龄、体质量和体况接近的安格斯（AG）、利木赞（LM）、西门塔尔（SM）与当地黄牛的杂交育成公牛共24头,按品种分为4组,试验期100 d。结果表明：①参试牛头均日增体质量排序为：Ⅱ组、Ⅳ组〉Ⅲ组〉Ⅰ组,差异达到显著水平（P〈0.05）;②BPI均值排序为：Ⅳ组〉Ⅱ组〉Ⅲ组〉Ⅰ组,但差异不显著（P〉0.05）;BCS平均增长率（%）排序为：Ⅳ组〉Ⅲ组〉Ⅱ组〉Ⅰ组,且试验Ⅰ组与其余3组差异极显著（P≤0.01）;③饲料报酬（耗料量/增质量）排序：Ⅲ组〉Ⅱ组〉Ⅳ组〉Ⅰ组;④参试牛头均纯收益、总投入占产出比及新增投入占产出比排序均为：Ⅲ组〉Ⅱ组〉Ⅳ组〉Ⅰ组。研究表明,在规模化肉牛生产中,应用推广全株玉米混合日粮饲喂技术,育肥效果更好。

This experiment is to study on effect of whole corn silage mixed ration feeding beef cattle fattening.Choose 24 crossbreed bred bulls from Angus（AG）×Local cattle、Limousin（LM）×Local cattle、Simmental（SM）×Local cattle with similarly age、weight and body condition.By species,they were divided into four groups,trial period 100 days.The results indicated that：①Average daily gain per cattle： Ⅱ（LM）、 Ⅳ（SM2） Ⅲ（SM1）Ⅰ（AG）,it was significantly different between the four groups（P0.05）;②The average of BPI per cattle： ⅣⅡⅢⅠ,the change of BPI was not obvious（P0.05）,the average of BCS growth rate（%）：ⅣⅢⅡⅠ;the difference between groupⅠand other groups was significant（P≤0.01）;③Feed efficiency（feed consumption volume / increase quality）： ⅢⅡⅣⅠ;④Average net income per cow cattle、the ratio of the total investment share of output and new investment share of output： trail groupⅢⅡⅣⅠ.The experiment indicated that better fattening to application to whole-plant corn mixed ration feeding techniques in the large-scale beef cattle production.
