【摘要】：为了给提高苏淮猪繁殖性能的选育工作提供技术支持,选取经产母猪344头,检测了苏淮猪群体内雌激素受体1(ESR1)、卵泡刺激素β(FSHβ)基因的多态性,分析单个基因型及合并基因型与总产仔数、产活仔数和初生重的关联性。结果显示:在ESR1基因中,A等位基因与B等位基因的基因频率相近,分别为0.541和0.459;AA型基因型频率为0.308,AB型为0.465,BB型为0.227;不同基因型苏淮母猪的总产仔数、产活仔数和初生重无显著差异(P0.05)。在FSHβ基因中,A等位基因与B等位基因的基因频率分别为0.148和0.852;AA型基因型频率为0.027,AB型为0.241,BB型为0.732,不同基因型苏淮母猪的总产仔数、产活仔数和初生重无显著差异(P0.05);ESR1和FSHβ基因合并基因型与总产仔数、产活仔数以及初生重无关联(P0.05)。ESR1和FSHβ基因与苏淮猪母猪的总产仔数、产活仔数以及初生重性状不相关。
[Abstract]:In order to provide technical support for improving breeding performance of Suhuai pigs, 344 sows were selected to detect the polymorphism of estrogen receptor 1 (ESR 1) and follicle stimulating hormone (FSH 尾) gene in Suhuai pig population. The relationship between single genotype and combined genotype and total litter size, live litter size and birth weight was analyzed. The results showed that the frequencies of allele A and allele B of ESR1 gene were similar, 0.541 and 0.459 AA genotype, respectively, and the frequency of genotype 0.308 A and AB genotype were 0.465 and 0.227 respectively, and the total litter size of different genotypes of Suhuai sows was 0.227, respectively. There was no significant difference in litter size and birth weight (P 0.05). In the FSH 尾 gene, the frequency of allele A and allele B were 0.148 and 0.852A genotype, respectively. The frequency of genotype AA was 0.027 and the frequency of genotype AB was 0.241 and BB was 0.732.The total litter size of different genotypes of Suhuai sows was 0.73 2. There was no significant difference between live litter size and birth weight. There was no significant correlation between the genotype of ESR1 and FSH 尾 gene and total litter size, and there was no correlation between live litter size and birth weight. ESR1 and FSH 尾 genes were not correlated with total litter size, litter size and birth weight traits of Suhuai sows.
