Abstract :The objective of this study was to assess the hatch window, hatchability and quality of broilers` chick obtained from different breeder strains in a commercial hatchery. A total of 57 600 hatching eggs insert ignore into journalissuearticles values(28 800 hatching eggs per strain); were collected from commercial flocks of Cobb 500 and Ross 308 broiler breeder parent stocks at 60-61 weeks of age. Each strain was randomly coded as A strain and B strain. The mean value of eggshell temperature was found to be higher in eggs obtained from Strain A insert ignore into journalissuearticles values(101.05 ⁰F); than the other eggs of Strain B insert ignore into journalissuearticles values(100.98 ⁰F, P<0.01);. The percentage of hatched chicks at 486 h of incubation period was found to be as 82.1% and 62.6% of Strain A and Strain B eggs respectively, whereas 84.9% and 67.7% of Strain A and Strain B eggs at 498 h of incubation period insert ignore into journalissuearticles values(P<0.01);. The relative chick weight was found to be higher in the chicks obtained from Strain B insert ignore into journalissuearticles values(67.5%);, compared to the Strain A insert ignore into journalissuearticles values(65.9%; P<0.01);. These findings could be instructive for commercial hatcheries about the requirements of the hatching eggs obtained from different breeder strains at particular age and contribute the optimization of eggs` management and processing.
