摘要/Abstract

摘要： 为了研究日粮中添加酿酒酵母培养物对肉牛生产性能及经济效益的影响,试验选择150头西门塔尔杂交肉牛,随机分成对照组和试验组2个组,每组75头。其中,对照组肉牛饲喂养殖场现行日粮（TMR）,试验组肉牛在养殖场现行日粮基础上添加0.5%酿酒酵母培养物,试验期为90 d。结果表明,试验组肉牛比对照组肉牛日增重提高9.68%（P〈0.05）,料重比降低1.79%（P〈0.05）,经济效益提高9.09%。该试验结果表明,在肉牛日粮中添加酿酒酵母培养物可提高肉牛的生产性能与经济效益。

Abstract: This study was aimed at evaluating the effects of dietary supplementation of yeast culture on productive performance and economic benefits of beef cattle. A total of 150 Simmental crossbred cattle were randomly assigned to one of two groups such that control group（n=75） fed the TMR diet prepared in the experimental cattle farm and experimental group（n=75） fed the TMR diet supplemented with 0.5% of yeast culture. The experimental period lasted for 90 days. The results revealed that the daily gain and economic benefits were found increased by 9.68%（P〈0.05） and 9.09% in the experimental group compared to the control group respectively, and the ratio of feed to gain was found decreased by 1.79%（P〈0.05） in the experimental group compared to the control group. The results obtained in this study suggest that supplementing the basil diet with yeast culture improves the productive performance and economic benefits of beef cattle.
