Abstract

Tibet pig is a special Chinese indigenous pig breed, which could survive in high-altitude areas of Tibet. In the present study, the genotypes of ESR, FSHbeta, and PRLR gene, the three known major genes of reproductive traits, were identified in 202 Tibet pig individuals. The results showed that the predominant genotypes of ESR, FSHbeta, and PRLR gene were BB, AB and AA, respectively. The genotype frequencies of the three genes were in Hardy-Weinberg equilibrium. The frequencies of desired alleles of the three genes were higher than those of other alleles, which indicated that Tibet pig had a good potential for improving reproductive traits.

摘要

藏猪是中国特有的地方猪种，能在西藏高海拔地区生存。在本研究中，对202头藏猪个体进行了繁殖性状的三个已知主要基因——雌激素受体（ESR）、促卵泡素β（FSHβ）和催乳素受体（PRLR）基因的基因型鉴定。结果表明，ESR、FSHβ和PRLR基因的优势基因型分别为BB、AB和AA。这三个基因的基因型频率处于哈迪-温伯格平衡。这三个基因的有利等位基因频率高于其他等位基因，表明藏猪在改善繁殖性状方面具有良好潜力。
