摘要: 试验选择野家杂交猪(大白猪和野猪杂交)F1代猪群261头,采用PCR-RFLP法进行了PRL基因的基因型和等位基因频率检测及不同基因型的仔猪初生重、30日龄体重和有效乳头数效应分析。结果表明,BB型个体仔猪的初生重、30日龄体重略高于其他基因型个体,而CC型个体的有效乳头数略高于其他基因型个体,但差异均不显著。 

Abstract: Genotype and allele frequencies of PRL in two hundred and sixty one hybrid pigs were detected by PCR-RFLP. The relationship between different genotypes and birth weight, body weight on 30 days and effective teat number were analyzed. The results showed that birth weight and body weight on 30 days of BB were higher than others, and effective teat number of CC was higher than others, but the difference was not significant.

Key words: pig; PRL gene; birth weight; body weight on 30 days; effective teat number
