Abstract

Background and Aim: The Goliath chicken is a slow-growing chicken with a high slaughter weight but whose carcass characteristics and meat quality have not yet been documented. This study aimed to evaluate the effect of age at slaughter and sex on the carcass characteristics and technological and sensory meat quality of Goliath chickens raised in southern Benin.

Materials and Methods: Data on the carcass characteristics and technological and sensory quality of meat were collected from 80 chickens raised in confinement and divided into two groups. The first group was reared for 12 weeks of age and the second group was for 20 weeks of age. The animals were individually weighed using an electronic balance (Terraillon 5000g) and then slaughtered. The different parts of the chicken carcass was weighed using the same method.

Results: The live, hot carcass, cold carcass, wing, thigh, and tail weights of males were significantly greater than those of females (p < 0.01). The wishbone muscle and thigh and tail assembly pH was lower in the 20-week-old chickens than in the 12-week-old chickens. The brightness and red index of the wishbone of the 20-week-old chickens were significantly higher than those of the 12-week-old chickens (p < 0.001). The red index of the wishbone and the yellow index of the thigh and tail assembly of females were lower than those of males.

Conclusion: The meat of 20-week-old Goliath chickens was juicier than that of 12-week-old chickens. Thus, the carcass composition of Goliath chickens is better at 20 weeks of age, especially in males.
