摘要：

试验选择8头肉用牛,设计2个不同蛋白质补充料来源精料的日粮,即以DDGS为主的试验组和以棉籽粕为主的对照组,粗饲料为玉米芯,采用全收粪的消化试验测定日粮营养物质表观消化率。结果表明,不同蛋白质来源的试验组和对照组日粮有机物、粗蛋白质、中性洗涤纤维、酸性洗涤纤维的表观消化率没有差异(P>0.05),肉牛日粮有机物、粗蛋白质、中性洗涤纤维、酸性洗涤纤维的表观消化率的变化范围分别为65%～71%、60%～70%、68%～70%和63%～65%。

摘要：

Eight beef cattles were divided into two groups,and they were fed with the dietary containing concentrate and corn cobs. The concentrate contained different protein source,among them DDGS was tested group and cottonseed meal was control group. The apparent digestibility of dietary nutrients was determined through digestion test by total feces collection method. Results showed that apparent digestibilities in total tract of organic matter,crude protein,neutral and acid detergent fiber were unaffected by protein sources significantly. The variation ranges of apparent digestibilities of organic matter,crude protein,neutral and acid detergent fiber in beef cattle ration were 65%～71%,60%～70%,68%～70% and 63%～65%,respectively.
