摘    要:目的]调查麟和FSH-β基因与长白猪繁殖性状的关系。方法]采用PCR—RFLP技术分析了长白猪FSH-β基因和PRLR基因的多态性及其与繁殖性状的相关性。结果]FSH-β基因3个基因型从、AB、BB在长白猪中的频率分别为0.035、0.075、0.890;PRLR基因3个基因型AA、AB、BB在长白猪中的频率分别为0.154、0.585、0.251。FSH-β基因对长白母猪的各项繁殖性状影响不显著;PRLR基因对长白母猪的总产仔数、产活仔数、初生窝重和断奶窝重影响显著,并呈现出AB〉AA〉BB的趋势。结论]该研究为PRLR和FSH-β2个基因的应用提供基础数据。

关 键 词:  FSH-β基因  PRLR基因  繁殖性能

Abstract:Objective] The study aimed to investigate the relation of the FSH-β gene and PRLR gene to the reproductive performance of Land-race sows. Method] The genotypes of FSH-β gene and PRLR gene in a landrace population were detected by using PCR-RFLP technology, and the relations to reproductive traits were analysised. Result] The genotype frequency of AA, AB, BB of FSH-β gene in Landrace sows was 0.035, 0.075 and 0. 890, resp. and the genotype frequency of AA, AB, BB of PRLR gene Landrace sows was 0. 164, 0.585 and 0.251, resp. The various reproductive traits were not affected significantly by FSH-β gene in Landrace sows, while the reproductive traits such as total number born, number born alive, birth litter weight and weaning weight of litter were affected significantly by PRLR gene and showed a trendy of AB > AA > BB. Conclusion] This study provide the foundational data for application of FSH-β gene and PRLR gene.
Keywords:Sow  FSH-β gene  PRLR gene  Reproductive performance
