摘要
对高寒草地放牧绵羊4种不同生产模式研究,结果表明:生产模式Ⅰ和生产模式Ⅱ,羔羊初生重、2月龄重及2月龄日增重有极显著差异(P<0.01);生产模式Ⅰ和生产模式Ⅱ,母羊产羔率和2月龄羔羊的成活率高于生产模式Ⅲ和生产模式Ⅳ,差异极显著(P<0.01);生产模式Ⅰ和生产模式Ⅱ单位母羊生产利润明显高于生产模式Ⅲ和生产模式Ⅳ。
Through the research of 4 different model of production, the result showed that： for the model I and model II, the lamb birth weight, two months＇ weight and daily gain in the age of two months had a significant difference （P〈0.01）; the lambing rate of ewes and the survival rate of lambs of the model I and II were higher than the model m and IV, there was a significant difference（P〈0.01）; the unit profit of ewe lambing of the model I and II were obviously higher than the model III ,and IV.
