dc.description.abstractBackground and Objective: Throughout the world, consumers are increasingly being attracted to chicken meat from naturally grown birds. A study was therefore conducted to evaluate the effect of dietary regimes on carcass and meat quality of genetically improved dual-purpose chicken. Materials and Methods: In total, 480 day-old male chicks were randomly assigned to 24 treatment combinations in a 2×3×4 factorial experiment. The treatments were breeds (Sasso and Kuroiler), diets (D 1 , D 2 and D 3 ) and levels of supplementation (100, 75, 50 and 25%). At the age of 20 weeks, five male chickens were randomly selected from each treatment combination and sacrificed for detailed carcass and meat quality assessment. Results: The Dressing Percentage (DP), pH, cooking loss, Crude Protein (CP) content of breast, thigh and drumstick joints were higher in Sasso than in Kuroiler. Values for redness (a*) and yellowness (b*) were higher in Kuroiler than in Sasso. Thigh muscle in birds fed D 2 and D 3 tended to be tougher than those fed D 1 . CP and ash contents in breast joints from D 1 and D 2 were higher than in D 3 chickens. The ether extract values for drumstick from D 1 and D 2 were comparable but higher than in D 3 . The L* and a* value in the breast joint tended to increase with a reduction in the level of supplementation but it was the opposite in the case of the drumstick. Conclusion: It is concluded that the feeding regime affects the meat quality of genetically improved dual- purpose chicken in a joint-specific fashion.
