摘要: 为探讨河南小尾寒羊体尺指标与体重的相关性,更好的服务于选种、选育工作,作者运用SPSS软件对98只河南小尾寒羊的体尺、体重进行了相关分析和通径分析,并建立了最优回归方程。结果表明,河南小尾寒羊的体重(〖AKY-〗)与体高(X1)、体长(X2)、胸围(X3)、胸宽(X4)、胸深(X5)、尾宽(X6)、尾长(X7)呈极显著正相关(P<0.01);体长、胸围、胸宽和胸深4个指标对体重的直接作用和间接作用都极大;得到最优回归方程为:〖AKY-〗=0.226X2+0.535X3+0.200X4。

Abstract: In order to research the correlation between body size and body weight of Henan small tail han sheep and dedicate to new breeding selection work. This paper analyzed the correlation between body size and body weight of 98 Henan small tail han sheep with the SPSS software, based on Path Analysis and Correlation Analysis, and establish the most superior regression equation. The results showed that the body weight(〖AKY-〗) with the body height(X1), the body length(X2),the heart girth(X3),the chest width (X4), chest depth(X5), tail width(X6) and tail length(X7) were significantly positive correlations (P<0.01). The direct action and the indirect action of the body length, the heart girth, the chest width and chest depth were extremely maximum. The most superior regression equation was 〖AKY-〗=0.226X2+0.535X3+0.200X4.

Key words: body weight; body length; chest width; direct action; indirect action
