促卵泡素β亚基基因和雌激素受体基因多态性对淮猪新品系产仔数的影响

Relationship between the Polymorphism of FSHβ and ESR Gene and Litter Size in Huai Swine Lines

此研究发现,在淮猪新品系Ι世代中具有促卵泡素β亚基(FSHβ)基因和雌激素受体(ESR)基因的多态性。FSHβ基因中A基因频率(60.53%)高于B基因频率(39.47%);ESR基因中C基因频率(64.47%)高于D基因频率(35.53%)。不同基因型与初产产仔数的研究结果表明,淮猪新品系FSHβ基因的3种基因型中,AA基因型的产仔数最高(11.58头),比AB基因型高1.68头,比BB基因型高1.51头;FSHβ基因和ESR基因的合并基因型,以BBDD型和AACD型产仔数最高,分别为12头和11.83头。

The result of this paper shows that there are polymorphism of FSHβ and ESR gene in Huai swine lines.Frequency of allele A gene of FSHβ gene （60.53%） is higher than that of allele B gene （39.47%）; While in ESR gene, frequency of allele C gene （64.47%） is higher than allele D gene （35.53%）. Relationship between genotype and first litter size shows that AA genotype of FSHβ gene has the highest litter size （11.58）, which has 1.68 more piglets than genotype AB and 1.51 more piglets than genotype BB. For combined genotype of FSHβ and ESR gene genotype, BBDD（ 12）and AACD （ 11.83）has the highest litter size.
