Study On The Relationship Between Polymorphisms Of Chiken FATP1 Gene And Slaughter Traits

Today,the Succulent problems is a key and major issue in poultry breeding.How to control Succulent in molecular level and choose become the focus of breeding searching In recent years.FATP gene family,"fatty acid transporter(Fatty Acid Transport Protein)" first discovered the name FATP1,the rest were FATP2,FATP3,FATP4,FATP5,FATP6.FATP1 mainly involved in transmembrane transport of and long-chain fatty acids transfer.It aslo get relation of the Content in TG from skeletal muscle.In this experiment,the research subjects is four kinds of chicken in Guangdong (Qingyuan Chicken,Xinghua Chicken,Huxu chicken,Xia yan chicken),and Sichuan mountain Silkies chiken,as well as the high-quality Daheng chiken for a total of 285 Individual.PCR-SSCP,and sequencing of the PCR product were Using in Researching of FATP1,and analysis the difference from differ genotype which in unsame Slaughter Traits between different polymorphism point.In this way to find the relevence between FATP1 and slaughter traits.Aslo it could provide reference in breeding tag of chicken.Mutations were found in two introns and one exon in FATP1.Through least squares analysis and test of significance was found that on the A sites,AA and AB and BB genotypes of the leg muscle weight,live weight,carcass weight difference was extremely significant.The remaining significant differences between characters.A allele of slaughtering traits have positive additive effect.Their additive effect values were 2.20g, 3.51%,1.1g,3.76%,265.4g,54.06g,263.46g.On the chest and the whole bore a net negative rate of the additive effect,AA genotype of abdominal fat weight,muscle weight and leg weight to the advantages in terms of genotype.On the B site,the genotype of the leg weight and chest muscle re-obvious advantages for the advantage of genotype,T allele could be further validation of the advantages of the slaughter traits.With the terms of the C locus,CC and CT and TT genotypes of the breast muscle weight,leg muscle weight, carcass weight significantly(P＜0.05),the remaining characters were no significant differences(P＞0.05).T gene on abdominal fat weight,muscle weight,all net-bore rate, live weight,carcass weight,leg muscle weight,subcutaneous fat thickness have a positive additive effect.Their values were 1.38g,12.5g,0.6%,44.19g,79.4g,18.6g,0.06mm.On the chest of the reverse rate of additive effect,additive effect value of 0.31%,the genotype of the legs TT muscle weight and muscle weight advantage genotype.
