Comparison of the Performance of Hybrids Obtained from Reciprocal Crosses between Anadolu–T and Cobb500 Parent Stocks

This study aimed to compare the performance of hybrids obtained from crosses between Anadolu–T hybrid breeders and commercial parent stocks. The hybrid combinations evaluated were Anadolu–T × Anadolu–T (AA), Cobb × Cobb (CC), Anadolu–T male × Cobb female (AC), and Cobb male × Anadolu–T female (CA). Throughout the 6-week growth period, including the initial body weight, significant differences were observed among all hybrid lines in terms of weekly live weights and body weight gains (p < 0.001). Except for the first week, the weekly live weight values of CC and AC were similar, with no statistically significant differences between these groups (p > 0.05). The average slaughter weights were 3005.00 g for CC and 2952.81 g for AC, respectively. Statistical analyses indicated that differences in weekly feed intake (WFI) among the hybrids were significant during the first four weeks (p < 0.01 and p < 0.05), while cumulative feed intake (CFI) values differed significantly during the first three weeks (p < 0.01). Cumulative feed conversion ratio (FCR) values at 6 weeks of slaughter age, which form the basis of economic efficiency indices, were examined, statistically significant differences were determined among the hybrids (p < 0.01). The values of the CC and AC genotypes were similar, with cumulative FCRs of 1.61 and 1.63, respectively, whereas the cumulative FCR values obtained from the CA and AA genotypes were calculated as 1.68 and 1.78, respectively.
