Comparison of Some Carcass Components of Selected Japanese Quail Lines in terms of SNP Haplotypes#

In this study, we investigated the effect of SNP haplotypes on insulin-like growth factor gene (IGF-1)related with weights of body, back, chest, leg and wing in the fifteen generation selected Japanese quail (C. coturnix japonica) lines according to the 5th week live weight. 8 SNP haplotypes were identified in the 167-bp DNA sequence of the IGF-1 gene coding region identified in a total of 108 individuals from three quail lines (control, high body weight: HBW and low body weight: LBW). ANOM (Analysis of Means of Analysis) was performed to determine the relationships between carcass components with SNP haplotypes and to compare quail genotypes. There were significant differences between the quail lines in terms of SNP haplotypes. As a result, it was determined that fifteen-generation selection in Japanese quails resulted in differences in insulin-like growth factor-1 gene and these differences were reflected in carcass components.
