藏猪雌激素受体基因、促性腺激素β基因多态性及其对产仔性状的影响
Polymorphisms and Effects of ESR and FSHβ on Litter Size of Tibetan Pigs
摘要
Abstract
[Objective]Polymorphisms of ESR and FSHβ and relation of the genes with low litter size of otherwise robust Tibetan pig were investigated.[Method]Polymorphisms of FSHβ and ESR in randomly selected 66 Tibetan pigs were detected using the PCR-RFLP method to correlate with the animal reproductive performance.[Result]Significant polymorphisms were found in the genes.In ESR,the frequency of AA genotype was 0.152,that of AB genotype 0.288,and that of BB genotype high at 0.560.Statistically,the frequency of allele A in ESR was 0.296,and that of allele B,0.704.Thus,BB was the dominant genotype and B the dominant allele.On the other hand,in FSHβ,the frequencies were 0.379 for AA genotype,0.288 for AB genotype,and 0.333 for BB genotype,while those for allele A were 0.523 and for allele B 0.477.Thus,AA genotype and A allele were dominant in FSHβ.The association analysis suggested that the ESR-BB and FSHβ-AA genotypes contributed significantly to the low litter size of the pigs(P＜0.05).[Conclusion]The B allele of ESR and the A allele of FSHβ could potentially be served as the genetic markers for breeding selection to improve the reproductivity of Tibetan pigs.关键词
