摘　　要：以内蒙古草甸草原中特有的乌珠穆沁羊为研究对象,选取不同典型牧户,采用控制性试验,以传统全年自由放牧作为对照组,研究冬季舍饲精喂对乌珠穆沁羊和当年羔羊日增重的影响。结果表明,母畜在怀孕期前后的舍饲精喂,可以保持母畜在下一年持续稳定地增重,其全年日增重与对照组有显著差异(P<0.05),且母畜在不同时间段所表现出的差异也不相同。不同种类的母畜日增重变化对冬季舍饲反应基本一致,日增重都高于对照组,且母绵羊和羯羊有显著差异(P<0.05)。对当年羔羊日增重的T检验分析,羔羊的日增重在不同时期都显著高于对照组(P<0.05)。因此,冬季舍饲精喂对改变典型家庭牧场饲养方式具有重要意义。In the study,Wuzhumuqin sheep was selected to tested,the greenhouse feeding effect of daily weight gain of Wuzhumuqin sheep was determined by control trial with the selection of different typical model of raising house,the control group was free-pasturing all the year.The results showed that gestation period of female livestock was fed by house and fined feeding,which could keep increase continuously to a certain degree in the next year,and the yearly weight gain was higher that of the control,the difference was marked（P0.05）,meanwhile the female in weight gain also was different at the different stage.The different varieties female livestock in daily weight gain was the same,the weight gain was higher that that of the control,but there was markedly different between female sheep and caprine（P0.05）.The result of T test showed that lamb in daily weight gain all was higher that of the control at the different stage.Hence,greenhouse feeding has significance to change traditional raising model.
