| 摘 要： | 以60周龄和自繁后的12周龄的如皋鸡作为试验材料，采用PCR-SSCP技术对细胞外脂肪酸结合蛋白（EX-FABP）基因进行单核苷酸多态性及遗传特异性分析。结果检测到2个SNP突变，分别为4271 G/A、4281 G/A突变，有3种基因型。最小二乘差异显著性检验结果表明，在60周龄时，AA型含量最高，显著高于AB型（P<0.05）；12周龄时，AB型含量最高，BB型最低；60周龄的肌内脂肪含量显著低于12周龄时的含量（P＜0.05）。

| Abstract: | This study was designed to investing the single nucleotide polymorphism and analyzing the genetic specificity of the EX-FABP gene, utilizing the PCR-SSCP technology and DNA sequencing, the 60 weeks of age and reproduction of the 12-week-old Ru-gao chicken as the experimental material. It detected three genotypes, two SNP mutations, 4271 G/A，4281 G/A respectively. The results showed that the content of AA-type was the mostly at the 60-week-old, significantly higher than the AB-type（P<0.05）, using the least-squares significant difference test. At the 12- week-old, the AB-type was in the highest levels, as well as the BB-type was minimum in three genotypes. The intramuscular fat content at 60-week-old was significantly lower than that of the 12-week-old（P＜0.05）. |
