A study was conducted to compare the carcass characteristics of indigenous Siruvidai, Kadaknath and Nandanam Broiler-3 chicken reared under cage system of management. The birds were reared in brooder cages from 0 to 12 weeks of age and grower cages from 13 to16 weeks of age. A total of 24 birds (12 males + 12 females) were selected randomly from each genetic group to study the carcass characteristics. The pre-slaughter body weight and processing yields like New York dressed, eviscerated and ready-to-cook yields were significantly (P<0.05) higher in Nandanam Broiler-3 compared to Kadaknath and indigenous Siruvidai chicken. In processing losses, Kadaknath birds showed significantly (P<0.05) higher feather loss (7.63 %) and head loss (4.76 %), while Nandanam Broiler-3 chicken had significantly (P<0.05) higher blood loss (2.92 %) but lower feather loss (5.48 %), indicating breed-specific variations in body components. The cut-up parts analysis revealed that breast yield was similar across all the breeds (25.28 to 25.78 %); while, Kadaknath chicken showed significantly (P<0.05) higher neck (10.29 %), drumstick (16.87%), and wing (11.73%) yields and indigenous Siruvidai chicken had significantly (P<0.05) higher thigh yield (14.29%). Indigenous breeds (Siruvidai and Kadaknath) showed significantly (P<0.05) higher giblets (6.04-6.67 %) and liver (1.82-1.84 %) yields, and intestinal measurements (13.42 to 13.44 % relative length) compared to Nandanam Broiler-3 chicken.
