摘要: 作者借助Excel和SPSS统计软件对测定的青海高原半细毛羊40只公羊和100只母羊的体重、毛长及体尺指标进行相关性分析和回归分析。结果表明,青海高原半细毛羊成年公羊的体重为90.2 kg,母羊体重为39.2 kg,毛长分别为10.1和8.7 cm,公羊和母羊体尺指标和毛长对体重的回归方程分别为:Y(体重)=-65.62+5.04X6(胸深)(P<0.01)和Y(体重)=-11.62+0.41X4(胸围)+0.76X5(胸宽)(P<0.01)。通过数据分析,为简化和改进选育技术提供参考。

Abstract: In this paper, the data of bodyweight,hair length and body size of Qinghai highland simifine wool sheep of 40 sires and 100 ewes were analysed by the computer procedures,using the Excel and SPSS software researched their correlation analysis and regression. The results showed that the bodyweight of adult sires and ewes sheep were respectively 90.2 and 39.2 kg,their hair length were respectively 10.1 and 8.7 cm,and while the regression equations were respectively Y(body weight)=-65.62+5.04X6(chest depth)(P<0.01),and Y(body weight)=-11.62+0.41X4(bust)+0.76X5(chest width)(P<0.01) for sires and ewes sheep. By this research,some references were afforded for simplification and improvement of selection technology
