| 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. |
| Keywords: | PCR-RFLPs PRLR ESR POLYMORPHISM LITTER SIZE |
