摘　　要：本试验通过观测肉羊TMR饲喂与常规饲喂的效果,表明TMR饲喂组平均日增重显著高于常规饲喂组(P<0.05),分别为233.72±25.14g和201.18±42.69g。在饲喂量相同的情况下,体重每增加1kg,TMR饲喂组比常规饲喂组少消耗精饲料0.39kg、粗饲料2.67kg。经90d舍饲育肥,TMR技术饲喂平均每只肉羊均比常规饲喂多收益87.6元,经济效益显著。In this experiment, Mutton Sheep were fed with fodder directly and with total mixture ration （TMR） to carry out a comparative study. The results showed that average daily gain of treatment group were higher than that of control group （P〈0.05）. The average daily gain of treatment group and control group were 233.72±25.14 g and 201. 18±42.69 g, respec- tively. The results demonstrated that feed cost of treatment group and control group were 4.24 Yuan and 12.77 Yuan when the cattle gain 1 kg weight （P〈0.01）. The experiment period was 90 d, and the average net income per animal in treatment group was 87.6 Yuan, which was higher than that of control group. Therefore, the economic benefit is remarkable.
