| 摘 要： | 笔者采用逐步回归的方法对随机抽测的青海省河南县40只欧拉型藏羊成年公羊和104只成年母羊的体重和8个主要体尺指标进行回归分析，得到欧拉型藏羊成年公羊体重和主要体尺指标的最优回归方程为y=0.88x2+13.64x6-4.35x7+1.28x4-114.51(P<0.01)；成年母羊体尺与体重的最优回归方程为y=0.49x1+0.46x2+0.30x3+0.43x4-43.51(P<0.01)。明确了欧拉型藏羊成年公羊和成年母羊体重与体尺指标的关系,为今后选育工作提供参考。

| Abstract: | In this paper,40 male sheep and 104 female sheep of Oura-type Tibetan sheep in Henan county of Qinghai province were selected to measure the body weight and body measurement.Then the regression analysis between body weight and body measurement was made by the Stepwise method of SPSS soft.The optimized regression equation is,y=0.88x2+13.64x6-4.35x7+1.28x4-114.51(P<0.01) for male sheep,and y=0.49x1+0.46x2+0.30x3+0.43x4-43.51(P<0.01) for female sheep. |
