Abstract :In this research, chicks from 3 broiler genotypeinsert ignore into journalissuearticles values(G);s insert ignore into journalissuearticles values(HY:Hybro, HB:Hubbart-flex ve RO:Ross 308); were grown to the 6th wks of age, and production performances, some carcass and meat quality properties were determined. As being the 3 G and 2 sex insert ignore into journalissuearticles values(S); with 4 replicates, totally 870 chicks in 24 sub groups were raised in the experiment. The data obtained were applied to statistical analysis as to the two factor insert ignore into journalissuearticles values(3x2); randomized plot design. There were no significant differences among G groups with respect to live weight insert ignore into journalissuearticles values(LW); at 6th wks of age. The males were given more insert ignore into journalissuearticles values(P<0.01); mean LW than females, as expected. As to the feed consumption insert ignore into journalissuearticles values(FC); at the end of 6th wks, while HY males consumed less insert ignore into journalissuearticles values(P<0.01); feed than HB and RO male groups, the differences between females were not significant. FC of males were higher insert ignore into journalissuearticles values(P<0.05); than the females. While RO groups had higher FC than HY, the difference with HB group was not significant. With respect to the feed conversion ratio insert ignore into journalissuearticles values(FCR); calculated as to the FC at the end of the 6th wks, HY group was found better than the others insert ignore into journalissuearticles values(HB and RO);. The males were showed lower FCR insert ignore into journalissuearticles values(better); than females. Effects of sex on carcass weight insert ignore into journalissuearticles values(P<0.01);, edible meat insert ignore into journalissuearticles values(P<0.05); and ratio insert ignore into journalissuearticles values(P<0.05);, bone insert ignore into journalissuearticles values(P<0.01); and ratio insert ignore into journalissuearticles values(P<0.05); were found significant. For these properties, males showed higher mean values than females. While RO G females showed lower insert ignore into journalissuearticles values(P<0.05); L* insert ignore into journalissuearticles values(lightness); mean values than all other combinations, the males also had shown lower insert ignore into journalissuearticles values(P<0.05); redness, a*, color value than the others. For the hardness value of thigh meat, while RO females were found most tender, HY females were found hardest and the difference between them found significant insert ignore into journalissuearticles values(P<0.05);. For pH value of the whole broiler meat, while males from HY and HB were higher insert ignore into journalissuearticles values(P<0.01); than their females and RO males, values of RO females had higher than the other females, but almost same with the males. The males have had higher insert ignore into journalissuearticles values(P<0.01); value than females for pH value of the broiler meat. While HY group meats have given higher insert ignore into journalissuearticles values(P<0.01); value for water holding capacity, given lower insert ignore into journalissuearticles values(P<0.05); value for cooking losses than the others.
