Carcass percentage of male KUB-2 KK chicken on different body weight

Abstract

KUB2 KK chicken is an improved KUB1 chicken, the improved local chicken created by the Indonesian Research Institute for Animal Production (IRIAP). Carcass percentage is an important indicator to evaluate the productivity of the slaughtered chicken. The objective of this research was to evaluate the carcass percentage of male KUB2 KK chicken on different body weights. 94 heads of ten weeks old male KUB2 KK chicken were used and it was divided into six bodyweight groups (G1: 700 to 799 g, G2: 800 to 899 g, G3: 900 to 999 g, G4: 1,000 to 1,099 g, G5: 1,100 to 1,199 g and G6: 1,200 to 1,299 g). Resulted data were analyzed using one-way ANOVA. The results showed carcass percentage of G1, G2, G3, G4, G5 and G6 were 61.12 %, 61.62 %, 62.50 %, 63.47 %, 63.72 % and 64.10 %, respectively. The group of body weight resulted significantly different on carcass percentage. Carcass percentage increased with increasing body weight. Thighs were the biggest part of the carcass. It was followed by breast, back, and wings. Abdominal fat had a tendency to increase by an increasing of body weight.
