Polymorphism of A-FABP Gene and Its Association Analysis with the Productive Performance in Male Baicheng Fatty Chicken
摘要
Abstract
In order to search the molecular genetic markers for breeding of Baicheng fatty chicken, the relationship between the polymorphism of adipocyte fatty acid binding protein (A-FABP) gene and the productive performance of the male chickens at different ages was studied.Ninety two chickens with age of 6 weeks were randomly selected.The polymorphism of A-FABP gene was detected by PCR-RFLP method.In each genotype group,fifteen chickens with similar body weight were categorized,each group was randomly divided into three sub-groups with equal num-bers.The productive performance of the chickens was measured at their age of 12,18 and 24 weeks.The results showed that there were three genotypes of A-FABP gene:AA,AB and BB, BB genotype was the dominant genotype,allele B was the advantageous allele,and it was not in Hardy-Weinberg equilibrium (P <0.01 ).At the age of 12 weeks,no significant difference was found among the measured productive performance (P >0.05).At the age of 18 weeks,it was found that the intramuscular fat width of BB genotype was significantly higher than AA genotype (P <0.05),the abdominal fat weight of BB and AB genotypes were extremely significantly high-er than AA genotype (P <0.01 ),and the abdominal fat weight percentage of BB and AB geno-types were significantly higher than AA genotype (P <0.05 ).At the age of 24 weeks,it was found that the body weight,intramuscular fat width and abdominal fat weight of BB genotype were significantly higher than that of AA genotype (P <0.05).Therefore,this results suggested that A-FABP gene could be used as a potential candidate marker for the association of fatty traits in male Baicheng fatty chicken.关键词
