【摘要】：为探讨雌激素受体基因(ESR)和卵泡刺激素β亚基基因(FSH-β)的多态性对大白猪繁殖性状的影响,本文采用PCR和PCR-RFLP技术检测大白母猪群的ESR和FSH-β基因多态性,并分析其对大白母猪总产仔数、总活仔数、健仔数、死胎、木乃伊数和初生窝重等性状的影响。结果表明:ESR和FSH-β基因的优势基因均为B等位基因;对于初产母猪,ESR和FSH-β基因BB型比AA型在总产仔数、总活仔数、健仔数性状上高0.06~1.14头(P0.05);对于经产母猪,ESR基因BB型比AA型总活仔数、健仔数分别高0.12头和0.07头(P0.05),FSH-β基因在总产仔数、总活仔数、健仔数性状上AA型高于BB型0.04~0.24头(P0.05);合并基因型分析发现ESR和FSH-β基因的有利合并基因型在初产母猪为ABAA,经产母猪为BBAA;BBAA合并基因型在总产仔数、总活仔数、健仔数性状上分别显著高于AAAA合并基因型2.03、1.75、1.65头(P0.05)。因此,ESR和FSH-β基因多态性与大白猪繁殖性状相关。
[Abstract]:In order to investigate the effect of estrogen receptor gene (ESR) and follicle stimulating hormone 尾 subunit gene (FSH- 尾) polymorphism on reproductive traits in white pigs, ESR and FSH- 尾 gene polymorphisms in large white sows were detected by PCR and PCR-RFLP techniques. The effects on the total litter size, total live litter size, healthy litter size, dead fetus, mummy number and birth litter weight of white sows were analyzed. The results showed that the dominant genes of the two genes were B alleles. The total litter size of ESR and FSH- 尾 gene BB genotype was higher than that of AA type in total litter size, total live litter size and healthy litter size traits, and the number of healthy piglets was 0.12 and 0.07 FSH- 尾 genes higher than that of AA type in the total litter size of ESR and FSH- 尾 gene BB genotype, respectively, compared with that of AA type, the total litter size of ESR and FSH- 尾 gene was higher than that of AA type, and the total litter size of ESR gene BB genotype was 0.06% higher than that of AA type, and the number of healthy piglets was 0.12 and 0.07 respectively higher than that of AA type. In total live litter size, AA genotype was higher than BB type 0.04 / 0.24 (P0.05N), combined genotype analysis showed that the favorable combined genotype of ESR and FSH- 尾 gene was ABAAA in the first sows, and the total litter size and the total live litter number in the total litter size and the total live litter size of the sows were BBAABBAA and BBAABBAA, respectively. The genetic polymorphisms of AAAA and FSH- 尾 genes were associated with reproductive traits of large white pigs.
