摘要
为了探讨成年萨福克母羊体尺与体重的相关关系,明确体尺对体重的直接影响和间接影响,试验对昌吉华兴牧场的萨福克羊进行体尺体重相关性分析。结果表明:体高(x1)、体长(x2)和胸围(x4)是影响萨福克成年母羊体重(y)的重要体尺指标;成年萨福克母羊估计体重的最优回归方程为:y=-20.52+0.65x1+0.41x2+0.14x4。
To explore correlation relationship between body size and weight of adult Suffolk ewes, and the direct and indirect effects of body size on body weight, Suffolk sheep fmm.Changji Huaxing pasture were chosen in this experiment and correlation analysis between body size and weight was conducted. The results suggested that body height（x1）, body length （x2）and hest circumference（ x4 ）were the important body size factors which effeeted body weight（y）of adult Suffolk ewes. The optimal regression equation of body weight of adult Suffolk ewes was estab- lishedy = -20. 52 ＋0.65x1 ＋0.41x2 ＋0. 14x4.
