Abstract


This study aimed to determine the growth and carcass traits of Anadolu-T broiler pure lines, which were kept breeding and selection over five generations from 2017 to 2021, in comparison with a commercial hybrid. After the selection process, pure lines (A1, A2, A3, B1, B2) and commercial hybrid (Ross-308) eggs were incubated and 120 female-male chicks were produced from each genotype in each generation. The broiler chickens were reared in broiler production standards for 6 weeks and carcass traits were determined by slaughtering at the end of this period. In this study, growth traits such as body weight (BW), feed conversion ratio (FCR), and livability; breast and thigh meat ratio were considered as carcass traits. The highest average BW (2961.2 to 3481.2 g) and best FCR (1.43 to 1.60) at 6 weeks of age over the five generations occurred in Ross-308 commercial hybrids; followed by sire (BW: 2633.8 to 3180.2 g; FCR: 1.65 to 1.77), dam lines (BW: 2307.7 to 2698.5 g; FCR: 1.65 to 1.78), respectively. Although there were some numerical differences in livability between generations in pure lines, it was generally at a similar level (96-100%) with commercial hybrids. The breast ratio was lower than commercial hybrid in both dam and sire lines, but it was determined that the thigh ratio was higher in pure lines. The fact that pure lines have a short selection history of five generations does not allow for detailed evaluation. We expect that the use of individual feed efficiency test in dam and sire lines, and additionally using body weight and breast
