Relationship between the SLC27 gene's polymorphism and some broiler carcass and economic factors

Abstract

This study was conducted at the poultry field, College of Agriculture and the Marshes, University of Thi-Qar from 10/11/2021 to 26/12/2021, and the Molecular Genetics Laboratories at the Marsh Research Center to determine the FATP gene polymorphism on some productive and physiological traits of broilers of ROSS 308. A total of 150 birds were used. The results of this study showed the following. Three genotypes were identified in the sequence of nitrogenous bases in the presence of the mutation G237A: GG, GA, and AA. It was noted that there were significant differences in the distribution ratios of the genotypes of the FATP gene according to the mutation G237A, where the genotype GA recorded the highest percentage, followed by genotype GG and then genotype AA. The G allele frequency is superior to the A. It was noted that there were no significant differences for the genotypes of the G237A mutation on the body weight and no significant differences between the GA, GG and AA genotypes of the FATP gene on the body weight, a significant difference in the genotypes of the G237A mutation on carcass weight, AA genotype outperformed the GG and GA genotypes, the AA genotype was superior to the GA and GG genotypes on wings relative weight.
