北京地区种猪氟烷基因分布的研究

The Preliminary Study on the Distribution of Halothane Gene in Breeding Pigs from Beijing Area

[目的]了解北京地区种猪群氟烷基因(Haln)的分布状况。[方法]采用PCR-RFLP对北京地区公猪站、种猪场共计609头种猪进行氟烷基因检测。[结果]公猪站大白猪、长白猪、杜洛克、皮特兰的Haln基因频率分别为0、17.11%、5.56%和18.75%;种猪场大白猪、长白猪、杜洛克的Haln基因频率分别为4.52%、11.68%和23.33%。[结论]该研究结果为合理利用氟烷基因提供依据。

[Objective] The aim was to investigate the distribution of the halothane（Haln） gene in breeding pig group in Beijing area.[Method] PCR-RFLP method was used to determine Haln genotype of 609 breeding pigs from boar stations and pig breeding farms in Beijing.[Result] The Haln gene frequencies of Large White,Landrace,Duroc and Pietrain pigs of the boar stations were 0,17.11%,5.56% and 18.75%,respectively;and the Haln gene frequencies of Large White,Landrace and Duroc pigs of pig breeding farms were 4.52%,11.68% and 23.33%,respectively.[Conclusion] The result provided a basis for the rational use of Haln gene.
