This experiment was conducted to compare the characteristics of the carcass between the phenotypic groups of different quail birds with the different plumage-colored and it's crossbreeding. In this experiment, 120 quail birds were used (parents of different color of feathers) (brown, white and desert). The eggs were collected and hatched and the resulting chicks were divided into four groups. It is brown ♂ × white ♀ And white ♂ × desert ♀ and white ♂ × brown ♀ and desert ♂ × white ♀ They were

Brown and desert birds surpassed brown over white and desert birds in the weight of the gizzard, which gave a higher weight. As for liver weight, significant differences appeared in favor of desert birds that outperformed brown and white birds. While the results of the statistical analysis did not show any significant differences for the characteristic of back weight, thigh weight, and heart weight between the three phenotypic groups. As for the effect of the phenotypic group of the offspring resulting from the crossbreeding, it was noticed that there are significant differences in the characteristics of the carcass between the four groups, where the first hybrid scored the highest body weight, followed by the third group, then the second and fourth. The first three groups outperformed the fourth group. As for the weight of the liver, significant differences appeared between the four hybrids in favor of the first hybrid over the rest of the hybrids, and the results of the statistical analysis did not show any significant differences in the characteristic of the heart weight between the phenotypic groups of the crossbreeding offspring.
