摘要: 试验采用PCR-RFLPs方法分析了长大、二花脸和大白猪的ESR、PRLR位点的多态性,并分析了多态性与母猪产仔性能和仔猪生长性能的相关性。结果表明:ESR和PRLR 2个位点在2个品种和长大母猪中存在多态性;PRLR位点的不同基因型对产仔数影响呈现出AA >AB >BB的趋势;ESR位点对产仔数影响的趋势为BB >AB >AA。2个位点对母猪乳头数、仔猪生长性能均不产生显著的影响。

关键词: PCR-RFLPs, ESR, PRLR, 多态性, 产仔数

Abstract: The polymorphisms of PRLR and ESR gene in Landrace×large white, Erhualian and Large white sow herd were investigated by PCR-RFLPs; the relationship between polymorphisms and growth trait were analysied. The results reveal that the polymorphisms of the two loci are found in different breeds and landrace×large white sow herd; the different genetypes of PRLR have different effects on litter size by the order AA >AB >BB; meanwhile ESR by the order BB >AB >AA. Neither has effect on pig growth and teat number.

Key words: PCR-RFLPs, PRLR, ESR, POLYMORPHISM, LITTER SIZE
