摘要: 本研究采用PCR-RFLP方法对苏太猪SLA-DQA基因多态性进行分析,结果表明,苏太猪
SLA-DQA基因开放阅读框第722个碱基存在1个A→G突变,从而导致了氨基酸Gly到Arg的转变,并产生了TaqⅠ酶切位点。当扩增产物被限制性内切酶TaqⅠ消化后,检测到AA和
AG基因型。分析这2种基因型与苏太猪生产性能间的相关性,结果表明:SLA-DQA基因与生产性能不存在相关性。

关键词: 猪; SLA-DQA基因; 生产性能

Abstract: The SLA-DQA gene in Sutai pigs was analyzed by PCRRFLP method, the
results showed that the 722 base of ORF in SLA-DQA gene has a A→G mutation , after digested by restriction endonuclease TaqⅠ,there showed two kinds of genotypes, AA and AG . The correlation between the two genotypes with the production performances in Sutai pigs was analyzed, the results showed that there was no correlation between the average production performances of the pigs with SLA-DQA gene.

Key words: pig; SLA-DQA gene; production performance
