对二花脸猪、大白猪及其杂交一代3个群体共计1686窝仔猪数的资料进行了遗传分析.结果表明猪总产仔数、活产仔数、20日龄仔猪数和45日龄仔猪数的遗传力分别为0.081、0.156、0.402和0.419。主效基因指数分析表明二花脸猪这4个性状均存在主效基因遗传。
對二花臉豬、大白豬及其雜交一代3箇群體共計1686窩仔豬數的資料進行瞭遺傳分析.結果錶明豬總產仔數、活產仔數、20日齡仔豬數和45日齡仔豬數的遺傳力分彆為0.081、0.156、0.402和0.419。主效基因指數分析錶明二花臉豬這4箇性狀均存在主效基因遺傳。

Genetic analysis was conducted on the data of 3 populations with 1686 litters including Erhualian pig, Large White and first cross. The results indicated that the heritability estimates for the total number of piglets born, the number of piglets born alive, the number of piglets at 20d and at 45d were 0.081, 0.156, 0.402 and 0.419,respectively. The major gene index analysis indicated that the prolificacy of Erhualian pig was influenced by major genes.
