Abstract: 为了研究湖北白猪繁殖性状的遗传规律,对湖北白猪的13头公猪及其80窝后代的繁殖性状表型参数和遗传参数进行了初步的估测。结果为平均产仔数10.24头,产活仔数8.81头,断奶头数8.025头,初生窝重11.79kg,泌乳力38.08kg,断奶窝重148.19kg,初生个体重1.32kg,断奶个体重18.87kg,乳头数13.85个,20日龄个体重4.70kg,妊娠期114.14d。遗传力分别为0.158、0.143、0.218、0.480、0.239、0.398、0.263、0.080、0.214、0.124。产仔数、产活仔数、断奶头数、初生窝重、断奶窝重、泌乳力等性状呈强的正相关,且窝性状的相关性都较强,窝性状和个体性状(初生个体重,断奶个体重)存在着负的遗传相关。
