Abstract:
The present investigation was carried out to characterize carcass traits in Indigenous and line Punjab Broiler 2 (PB2) birds. The Indigenous and synthetic colored broiler dam PB2 chicken groups, each consisting of two hundred birds, reared and maintained under standard management procedures at AICRP on Poultry Meat, Veterinary College, Bengaluru formed the experimental birds of this study and these birds were subjected for recording carcass traits. Carcass traits such as weights of carcass, wing, thigh, drumstick, neck, breast, back, abdominal fat, heart, liver and gizzard were recorded in both Indigenous and PB2 bird by sacrificing the birds at the age of 12th and 6th week, respectively. The carcass traits such as average weight (g) of carcass, wing, thigh, drumstick, neck, breast, back, abdominal fat, heart, liver and gizzard in Indigenous and PB2 birds were 633.07±9.73 and 867.50±10.49; 83.93±1.31 and 110.33±1.35; 87.86±1.81 and 130.68±1.93; 90.61±1.59 and 117.27±1.80; 52.07±1.19 and 66.80±1.38; 150.06±2.61 and 183.97±3.00; 115.73±1.87 and 145.07±2.81; 3.97±0.21 and 25.32±0.68; 4.52±0.13 and 8.82±0.30; 20.32±0.33 and 42.30±0.63 and 24.03±0.35 and 35.61±0.47, respectively. When these weights of different parts of carcass were expressed as percentage of live weights, the respective values in Indigenous and PB2 birds were 79.51±1.74 and 74.95±1.34; 10.56±0.24 and 9.49±0.13; 10.98±0.27 and 11.24±0.19; 11.40±0.29 and 10.01±0.14; 6.47±0.15 and 5.73±0.13; 18.86±0.43 and 15.84±0.28; 14.55±0.32 and 12.59±0.28; 0.49±0.03 and 2.19±0.06; 0.56±0.02 and 0.76±0.03; 2.75±0.07 and 3.66±0.07 and 3.07±0.10 and 3.09±0.06, respectively. Values of carcass traits as percentage of live weight were higher in PB2 than Indigenous birds for weights of thigh, abdominal fat, heart, liver and gizzard. Interestingly, dressing percentage, wing weight, drumstick weight, neck weight, breast weight and back weight were lower in PB2 than Indigenous birds. The genetic variabilities in the carcass traits of Indigenous and PB2 chicken of present investigation may be utilized for designing appropriate genetic improvement programs.
