中文摘要:

      [目的]肉牛全混合日粮（TMR）是一种将粗饲料、精饲料、矿物质、维生素和微量元素等其他添加剂充分混合搅拌均匀，将水分调到45%，能够满足肉牛营养需要的饲养技术。[方法]为了比较西门塔尔牛TMR饲喂与传统饲喂方式，在固原市瑞科丰农牧科技有限公司随机选取120头西门塔尔育肥公牛作为试验牛群，对照组和试验组各60头，试验组使用TMR日粮饲喂，对照组采用传统饲喂方式饲喂，观察育肥牛生长发育情况、体重变化。[结果]结果表明，TMR饲喂的肉牛平均体重（547.9 kg），比传统饲喂平均体重（509.24 kg），相对提高了7.6%（P＜0.01）。TMR饲喂平均日增重（1 331.6 g/d）比传统饲喂的平均日增重（1 194.5 g/d）相对提高了11.5%（P＜0.01），西门塔尔公牛育肥平均体重TMR饲喂785 kg，传统饲喂为752 kg，体重增加33 kg，提高4.4%（P＜0.05）；西门塔尔育肥公牛平均利润TMR饲喂比传统饲喂利润增加1 529.5元/头。[结论]西门塔尔牛TMR饲喂比传统饲喂优势明显，应在肉牛生产中大力推广。

英文摘要:

      [Objective]The beef total mixed ration is a breeding technique that it was mixed with roughage, concentrated feed, minerals, vitamins, and trace elements, the water is 45% to provide sufficient nutrients to meet the needs of beef cattle. [Method] To compare the TMR feeding of Simmental cattle with traditional feeding methods, 120 Simmental bulls were randomly selected as experimental cattle in Ruikefeng agricultural and animal husbandry technology Co., Ltd. in Guyuan city. The TMR diet feeding was used in the test group. The traditional feeding was used in the control group and the control group and the experimental group each had 60 heads. The growth and development and the change of body weight were observed. [Results]The results showed that the average weight of beef cattle fed with TMR (547.9 kg) was 7.6% higher than the average weight of traditional feeding(509.24 kg)（P＜0.01）. The average daily weight gain(1 331.6 g/d) of TMR feed increased by 11.5%（P＜0.01）compared to the average daily weight gain(1 194.5 g/d) of traditional feeding. The average weight of traditional feeding was 752 kg, TMR feed 785 kg, Weight gain 33 kg, an increase of 4.4%（P＜0.05）; The profit of the TMR feeding increased by 1 529.5 Yuan than that of traditional feeding. [Conclusion]The advantage of TMR feeding is more obvious than that of traditional feeding of Simmental, and it should be vigorously promoted in beef cattle production.
