Characteristics of carcass and non-carcass in F1 population crossbred brown and black Japanese quails

Abstract

The aim of this study was to evaluate characteristics of carcass and non-carcass in F1 population crossbred brown and black Japanese quails. A total of 80 birds have been raised under the same feeding and management in battery cage system. They were divided into four groups based on type of crossing. Brown male quail and Black female quail crossing produced Brown layer lines (BL12 and BL21 lines), on the other hand Black male quail and Brown female quail crossing produced layer populations called LB12 and LB21 lines. The data observed was live body weight, carcass and non-carcass percentages, and abdominal fat percentage. The data was analysed using analysis of variance and if there were pairwise differences among lines Duncan’s multiple range test (DMRT) was performed. Significant differences among lines have been found for live body weight, carcass and non-carcass percentages. Live body weight in LB12 and LB21 populations were significantly higher than others (P<0.001). In addition, highest carcass percentage and lowest non-carcass percentage were found in LB12 population (P=0.0175 and P=0.0159, respectively). Abdominal fat percentage was not different among lines. In conclusion, F1 population of LB line had overall better live body weight, carcass and non-carcass percentages than BL lines.
