用PCR-RFLP的方法检测了猪视黄醇结合蛋白4(RBP4)和整合素β1(ITGB1)基因在试验猪群中的多态性,同时分析其对大白猪产仔数、产活仔数、健仔数、初生窝重等性状的影响。结果显示:RBP4基因AA型产仔数、产活仔数、初生窝重显著高于AB、BB型(P<0.05),AA型健仔数极显著高于BB型(P<0.01),显著高于AB型(P<0.05)。ITGB1基因TT型产仔数、产活仔数、健仔数高于TC、CC型,差异均不显著(P>0.05)。RBP4与ITGB1基因9种合并基因型中AATT型产仔数、产活仔数、健仔数均高于其他合并基因型,差异均不显著(P>0.05)。
The polymorphism of RBP4 and ITGB1 gene in test pigs was detected by PCR-RFLP method. At the same time, the piglets’ litter size, live litter size , Aberdeen number, newborn litter weight and other traits. The results showed that the number of litter size, live litter size and the litter size of RBP4 gene were significantly higher than that of AB and BB genotypes (P <0.05) Higher than AB type (P <0.05). The number of litter size, number of alive pigs and number of healthy piglets in TT genotype of ITGB1 gene were significantly higher than that of TC and CC genotypes (P> 0.05). There was no significant difference in the number of litter size, live litter size and litter size of AATT among the 9 genotypes of RBP4 and ITGB1 (P> 0.05).
