摘　　要：[目的]为了推广犏牛异地育肥以及育肥过程中精料配方的合理筛选。[方法]选择体重,体况一致,年龄在2-3岁的实验犏牛30头,随机分为3组,每组10头,分别为实验Ⅰ、Ⅱ、Ⅲ组。分别饲喂对应的1,2,3号饲料。通过试验数据的记录分析。[结果]表明:在同样的环境和饲喂条件下,试验Ⅱ、Ⅲ组增重高于试验Ⅰ组,分别为237g(P<0.01)、295g(P<0.01),试验Ⅱ和Ⅲ组之间增重差异不显著(P>0.05)。[结论]从测定数据综合分析出在犏牛异地育肥精料配方筛选试验中增重、投入产出、经济效益Ⅲ组最高,因此大力发展犏牛异地育肥是提高农民增收的有效途径,精饲料配方技术简单易学,也是推动犏牛异地育肥的一项重要举措。[Objective]The aims of this study were to promote Pianniu offsite fattening and screen out the reasonable concentrate formulations. [Method] 30 Piannius, which were consistent in body weight, body condition, at the age 2-3, were randomly divided into three groups, each group 10, respectively, named group Ⅰ, Ⅱ, Ⅲ. Each group was fed with corresponding to 1, 2, 3 feed. The test data were recorded and analyzed. [Results]The results showed that： under the same environment and feeding conditions, the weight gain of experimental groups Ⅱ, Ⅲ were higher than that of group Ⅰ, which were 237g （P 〈0. 01）, 295g （P 〈0.01）, respectively. There was no significantly difference between experiment Ⅱ and Ⅲ groups （P 〉0.05）. [Conclusion] From the comprehensive analysis and considered the input and output, group Ⅲ had the highest economic benefit. Since Pianniu off-Site fattening is an effective way to improve the income of farmers, and feed formulation technique is simple and easy to learn, screening test of concentrate formula for Pianniu off-site fattening is important in science and application.
