【摘要】 为探讨槐山羊体尺指标与体重的相关关系,更好的服务于选种、选育工作,运用SPSS软件对179只槐山羊体尺、体重的测定结果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:槐山羊的体重(■)与体高(X1)、体长(X2)、胸围(X3)、胸宽(X4)、胸深(X5)呈极显著正相关(P<0.01);体高、体长、胸围、胸宽的直接作用和间接作用对体重的影响极大;得到最优回归方程为=0.353 X1+0.316 X2+0.234 X3。更多还原

【Abstract】 In order to research the correlation between body size and body weight of Huai goat and help selection and breeding,the determination results of body size and body weight of 179 Huai goats were analyzed by SPSS software with path analysis and correlation analysis,and the optimum regression equation was established.The results showed that there was a significant positive correlation(P<0.01) between body weight(■) and body size(body height(X1),body length(X2),the chest girth(X3),the chest width(X4) and the chest depth(X5).The body weight was extremely affected by the direct action and indirect action of body height,body length,chest girth and chest width.The optimum regression equation was: ■ =0.353X1+0.316X2+0.234X3.更多还原
