The Effect of Breeding System and Sex on Some Carcass Characteristics of Japanese Quail

Abstract

Abstract The objective of this study was to illustrate the impact of the breeding method and the gender of the birds on quail corpses. A total of 60 quail birds, consisting of 30 females and 30 males, aged 30 days, were utilized for this investigation. The birds were reared in two distinct systems: the first being the cage system and the second being the floor system. Each room was allocated for the separate accommodation of females and boys. At the conclusion of the trial, a total of 10 individuals (5 males and 5 females) from each system were euthanized in order to analyze the features of their carcasses. The results indicated that there was a significant superiority of the birds raised on the floor in the characteristics of carcass weight and the relative weight of the neck compared to the birds raised in cages, while no significant difference appeared for the effect of the rearing system. In the live body weight, the percentage of cleansing, and the relative weight of the thigh, wing, chest, back, and head. As for the effect of sex, a significant superiority was observed for females over males in the trait of live body weight, while males were superior to females in the trait of shedding ratio and relative weight of the back, and no significant difference appeared between males and females in the rest of the traits studied, while the effect of the interaction showed a significant superiority for females bred in Both systems compared to males in terms of live body weight, while males and females raised on the floor excelled in carcass weight compared to males raised in cages. A significant superiority was also observed for males raised in both systems in terms of mating ratio compared to females raised in cages and the floor, and males raised in cages excelled. In both systems, females raised in cages were superior to the relative weight of the back, while females raised in cages were superior to the relative weight of the neck to both sexes raised on the floor, and the interaction effect did not have any significant effect on the relative weight of the thigh, wing, chest, and head. We conclude from this that birds raised on the floor recorded a higher carcass weight than birds raised in cages, and males recorded a higher percentage of slaughter than females.
