摘要
本研究利用新荣昌猪Ⅰ系继代选育群1990—1995年后备猪培育、同胞肥试及繁殖母猪性能测定资料,估计出新荣昌猪Ⅰ系繁殖性状与生长、胴体性状之间的遗传相关。结果表明:繁殖性状与生长、胴体性状之间的遗传相关极弱,接近零。
Records on pigs for sib testing and sows of the selection population in New Rongchang Pig between 1990 and 1995, were used to estimate the genetic correlations of reproduction traits with growth and carcass. The results showed that reproduction traits had very small genetic correlations with growth and carcass traits.
