Resumo: ABSTRACT This study aimed to compare the eggs of the native-Turkish Atak-S (A-S) hybrid and the foreign brown layer Isa Brown (IB) and white layer Novogen White (NW) hybrids reared in two different cage densities (468.75 cm2/hen and 312.50 cm2/hen) in terms of the internal and external quality parameters of the eggs. A total of 540 hens including 180 from each genotype were used. To determine the egg quality characteristics, one randomly selected egg was taken out of each cage every 4 weeks in the yield period of 24-68 weeks, and analysis were carried out. A total of 648 eggs were used. In the study, the effect of genotype on all parameters was found to be significant. The shell thickness, Haugh unit and albumen index were lower in the Atak-S hybrid. In the white laying hens, the Haugh unit, albumen index and eggshell destruction strength values were higher, while the meat and blood spots and yolk color values were lower. Cage density did not create a significant effect on any parameter except for the blood and meat spot ratio. Age has a significant effect on the egg weight, shape index, Haugh unit, albumen index and yolk index. Consequently, as the native hybrid had similar destruction strength values to the others despite its lower shell thickness, and it had a Haugh unit showing good quality based on the food codex despite lower values than the others, it was concluded that it could compete with the foreign hybrids in terms of egg quality.
