摘　　要：[目的]为了掌握不同日粮对安格斯杂交阉牛生产性能的影响。[方法]试验对采用不同精粗比的全混合日粮对舍饲条件下杂交阉牛的育肥效果和生产性能进行研究。[结果]表明:随着时间的增加,精粗比为67.1∶32.9(粗蛋白12.86,消化能12.38MJ.kg-1)的全混合日粮对安格斯与秦川杂交阉牛的育肥效果优于精粗比为57.0∶43.0(粗蛋白质11.92,消化能10.82MJ.kg-1)和45.7∶54.3(粗蛋白质11.29,消化能10.62MJ.kg-1)。育肥杂交阉牛的增重得到显著提高,53d育肥日增重1 019.47g。[结论]说明在本试验条件下日粮的精粗比可有效提高安格斯牛与秦川牛杂交的育肥效果和生产性能。[Objective] In order to of Angus hybrid bullocks.
