摘要：

选择12月龄努比亚羊75只集中配种，配种后将母羊分随机分为3组，分别补饲复合预混料+尿素、浓缩料和精料补充料，在配种时、妊娠100d、妊娠150d进行体重、体况、体尺测量，同时记录母羊产羔数。结果表明：补饲精料补充料的母羊体重、增重和胸围均大于补饲浓缩料组和补饲尿素组，三组之间存在明显差异（P<0.05或P<0.01）。产羔数与母羊体况BCS和体况指数BCI密切相关，产0只羔羊母羊BCS和BCI在整个试验期间几乎没有变化，产1～3只羔的母羊BCS和BCI整个妊娠期都处于上升趋势。三组母羊产羔数分别为1.00±0.76、1.44±0.51、1.83±0.49只，羔羊出生重分别为2.25±0.18、2.51±0.37、2.64±0.40kg，组间差异显著（P<0.05或P<0.01）。母羊妊娠期体BCS和BCI变化情况一致，三组间存在显著差异（P<0.05或P<0.01）。妊娠150d母羊的体况BCS和体况指数BCI与产羔数显著相关，产羔数 =-0.4177BCS2+3.727BCS–4.9185（R2=0.9984）,产羔数=-0.0018BCI2+0.2795BCI-7.2278（R2=0.9985）。

Abstract:

75 Nubian ewes were selected (average body weight = 27.14±3.5kg) and divided into 3 groups randomly. Besides basic grazing, three groups of goats were treated 2% compound-premix plus urea 10g/d(the added urea group), concentrated feed 100g/d (the added concentration group)and concentrate supplement 250g/d (the added concentrate supplement group) respectively. Body weight, body conditions and body size were measured at the mating day, 100-day of pregnancy and 150-day of pregnancy, and the numbers of ewes lambing were recorded. The results as follows：Body weights, gain weights and chest girth were significant differences between three groups（P<0.05 or P<0.01）.There were close relationship between the numbers of lamb and BCS and BCI. The numbers of lamb of the added urea group, the added concentration group and the concentrate supplement group were 1.00±0.76, 1.44±0.51 and 1.83±0.49 respectively. The birth weights were 2.55±0.18, 2.51±0.37 and 2.64±0.40kg,there were significant differences between three groups（P<0.05 or P<0.01）. The BCS and BCI of 150-day of pregnancy and lamb numbers(x) have strong relationship：x=-0.4177BCS2 +3.727BCS–4.9185 (R2=0.9984)；x =-0.0018BCI2+0.2795BCI-7.2278 (R2=0.9985).
