| 摘 要： | 采用PCR-RFLP技术6个中外品种共245头猪的FUT1基因进行了研究, 结果表明, Hin 6Ⅰ位点上, 大白猪、长白猪和杜洛克猪3个外来猪种均存在多态, 且以敏感型(GG型和AG型)居多; 山西黑猪、太原花猪和马身猪3个本地猪种的所有检测样品都表现为GG型。用方差分析方法分析FUT1基因型、品种和胎次与产仔性状之间的关系, 基因型和品种对猪的总产仔数的影响显著, 胎次对总产仔数影响不显著。而基因型、品种和胎次对产活仔数影响均不显著。

| Abstract: | The genetic variations of FUT1 gene at nucleotide position 307 of its open reading frame were investigated by PCR-RFLP in a total of 245 pigs from 3 exotic pig breeds and 3 Chinese native pig breeds. Results showed that the genetic polymorphisms of the FUT1 locus were only detected in the 3 exotic pig breeds. There were 3 different genotypes and the majority were the susceptible forms including GG and AG. All Chinese native pig breeds only presented the susceptible genotype GG. Univariate analysis of variance components indicated that FUT 1 gene and the type of breeds significantly affected total number born, whereas parities did not. None of these factors significantly affected the number of liveborns. |
