【摘要】 利用相关和通径分析的原理与方法 ,对 2 8头贵州剑河白香猪 5个生长性状进行相关关系研究 ,剖析 3月龄猪 5个生长性状与 6月龄体重的直接效应与间接效应 ,并进行决定程度分析 ,揭示各生长性状间的真实关系 ,结果表明 ,3月龄体重与 3月龄体长、胸围、腹围 ,3月龄体长与 3月龄胸围、腹围 ,3月龄胸围与腹围密切相关 ,6月龄体重 (y)受 3月龄体重 (x1)的影响较大。采用逐步回归法 ,筛选出最优回归方程。因此 ,剑河白香猪早期生长应着重从 3月龄体重来探讨 6月龄体重。更多还原

【Abstract】 The correlation among 5 growth traits of taking 28 Jianhe white xiang pigs in Guizhou were studied,using the principle of correlation and regression analysis. The direct and indirect effects of body weight at 6 months with 5 growth traits at 3 months piglets and decision degree had been determined.The relationship among growth traits were analyzed,the results showed that body weight at 3 months with chest girth,belly girth,body length at 3 months with body length,chest girth,belly girth,chest girth with belly girth at 3 months were closely related, and body weight at 6 months(y)was mostly influenced by body weight at 3 months(x 1).The best regression equation was selected through further progressively regression method. Therefore,early growth of Jianhe white xiang pig should be studied through the 3 month body weight to research body weight at 6 months.更多还原
