A 2X2X4 factorial design was utilized to evaluate the production performance of two type of dual purpose commercial colour birds [G (JBP Col. 50% : Kd 50%) and G (JBP Col. 75% : Kd 25%)] under diversified 1 2 housing system and dietary protein level. A total number of 192 birds, 96 birds from each genetic stocks, aged 24 weeks were utilized for present experiment and distributed in to 32 replicate subgroups. The body weight was increased as the age advances and birds at attained the body weight 1.83 kg (G ) and 1.91 kg (G ) at 40th weeks of age. The average 1 2 feed consumption/day estimated were 106.10�0.12, 106.54�0.09, 105.59�0.07 and 97.26�0.05 g for G birds whereas 1 108.69�0.14, 111.42�0.12, 108.98�0.06 and 101�0.18 g respectively in P-I, P-II, P-III, P-IV. On overall basis deep litter housed birds consumed 5.24 g less feed per day than caged birds.
