Abstract

This experiment was done in the Poultry farm, Animal Production Department, College of Agriculture, Kirkuk University, form 2 April until 31 July 2022 to determine the effect of genetic line of three varieties of Japanese quail (White, Brown and Grey) and gender on the body weight and carcass components, 300 unsexed quail chick one day old were used placed in vertical battery cages for four weeks old then the birds were slaughtered and measured the parts weight.

The results also indicated the superiority of brown female’s Japanese quail in weight of carcass, breast, thigh, wings, gizzard and liver compared with other of effects.
