摘　　要：为了探讨高山美利奴羊冬季农区异地育肥效果,试验选在冬季将高寒牧区的高山美利奴羊羔羊160只移入饲草料丰盛的农区进行舍饲育肥,160只羔羊分为A1、A2、B1、B2共4个组,每组40只羔羊,A1、B1组为公羔,A2、B2组为母羔,A1、A2组饲喂常规的TMR全混合日粮(日粮A),B1、B2组饲喂添加了玉米的高能TMR全混合日粮(日粮B),对羔羊的相关体尺、体重、毛用性状进行测定分析,同时分析了高寒牧区羔羊异地农区舍饲育肥的经济效益。结果表明:饲喂日粮B的B组增重效果明显高于饲喂日粮A的A组;公羔的日增重效果明显高于母羔。4组羔羊的纯利润分别为297.20元、108.20元、372.20元、181.28元。说明高寒牧区羔羊异地农区舍饲育肥经济效益明显;羔羊饲喂添加玉米的高能TMR全混合日粮增重效果明显。In order to explore the effect of off-site fattening of Alpine Merino sheep in winter farming areas,160 Alpine Merino lambs in alpine pastoral areas were transplanted into farming areas with abundant forage for house feeding and fattening in winter.160 lambs were divided into four groups:A1,A2,B1 and B2,40 lambs in each group,A1 and B1 male lambs,A2 and B2 female lambs,A1 and A2 groups were fed with conventional TMR total mixed diet(diet A),B1 and B2 groups were fed with corn high-energy TMR total mixed diet(diet B),and the related body size,weight and wool performance of lambs were studied.The economic benefits of house feeding and fattening of lambs in alpine pastoral areas were also analyzed.The results showed that the weight gain effect of group B fed with diet B was significantly higher than that of group A fed with diet A,and the daily weight gain effect of male lambs was significantly higher than that of female lambs.The net profits of the four groups were 297.20 yuan,108.20 yuan,372.20 yuan and 181.28 yuan respectively.The results showed that the economic benefits of house feeding and fattening of lambs in alpine pastoral areas were obvious,and the weight gain of lambs fed with high energy TMR mixed diet supplemented with corn was obvious.
