%X In order to investigate the effect of ADFP gene on the carcass traits and intramuscular fat content of Da-heng high-quality chicken,we analyzed the coding sequence of the ADFP gene by single-strand conformation polymorphism(SSCP) and DNA sequencing in five pure lines and three crossbreds.We found three single nucleotide polymorphism sites,including A/T at base position 4 079(locus A),C/T at base position 4 843(locus B) and A/G at base position 7 070(locus C).GLM analysis for the effect of genotypes on carcass traits and intramuscular fat content demonstrated a significant effect on leg muscle percentage,abdomen fat weight,abdominal fat percentage and intra-muscular fat content in locus A(P < 0.05),a significant association with living body weight and carcass weight for locus B(P < 0.05) and a significant association with breast muscle weight and intramuscular fat content(P < 0.05),and a very significant association with breast muscle percentage for locus C(P < 0.01).It was concluded that ADFP gene may be a major gene or linked to such a gene that affects the fat traits of birds.Polymorphic loci A and C could be used as molecular markers for abdominal fat weight,abdominal fat percentage and intramuscular fat content in birds in future studies.
