【摘要】 为研究策勒黑羊公、母羊体重与体尺之间的相关关系，利用SPSS 26.0软件对50只策勒黑羊公羊和50只策勒黑羊母羊的体重数据做t检验分析，并对3月龄策勒黑羊体重与体尺数据进行深度分析。结果表示，3月龄策勒黑羊公羊最优回归方程为y_{策勒黑公羊}=0.395x₂+0.461x₃+0.85x₆-46.607;3月龄策勒黑母羊胸围、胸深对体重影响极显著（P<0.01），最优回归方程为y_{策勒黑母羊}=0.402x₃+1.012x₆-24.801。体长、胸围、胸深可作为3月龄策勒黑羊公羊选育的重要指标；胸深、胸围是3月龄策勒黑羊母羊选育的重要指标。更多还原

【Abstract】 With the purpose of searching the relationship between weight and body size in male and female Qira Black Sheep.We used SPSS 26.0 software to apply analysis of the weight data of 50 male Qira Black Sheep and 50 female Qira Black Sheep,in-depth analysis on the weight and body size data of 3-month-old Qira Black Sheep to establish the best weight and body size regression equation.Result display that the best regression equation at 3 months of age was y=0.395x₂+0.461x₃+0.85x₆-46.607;The body size data of 3-month-old Qira Black Sheep,the chest girth and chest depth of female Qira Black Sheep have a significant impact on weight（P<0.01）,with the best regression equation being y=0.402x₃+1.012x₆-24.801 for female Qira Black Sheep.Body length,chest girth,and chest depth can be important indicators for selecting male Qira Black Sheep at 3 months old;while chest depth and chest girth are crucial indicators for selecting female Qira Black Sheep at 3 months old.更多还原
