摘要：

本文测定了高原瘦肉型猪白系选育群几个世代的主要繁殖性能的表型参数,对遗传力及表型相关进行了估测。估测结果表明:繁殖性能的变异比较大,特别是断奶时的指标;遗传力除断奶窝重和乳头数外,其他性能均在0.2以下;繁殖性能间存在着较强的相关关系,其中断奶窝重与初生窝重呈正显著相关(P<0.05),且与产仔数、活产仔数、30日龄断奶头数均呈正极显著相关(P<0.01)。

摘要：

The phenotype parameters of main reporductive performances were determined in breeding hard of white line for plateau lean meat type of pig in the several generations and the correlation of heritability to phenotype was estimated.The results showed that the reproductive performances,especially the index at the weaning,were larger variation.The heritability of reproductive performancl were below 0.2 except the weaning weitght of litter and the number of nipple.There was a strong positive correation.Of them,there was the siginficant positive correlation between the weaning weight of litter and the newborn weight of litter(P<0.05);there was the very significant positive correalation of weaning weight of litter to the number born,the survival number born and the piglet number at weaning aged 30-day(P<0.01).
