A broiler stock PB-1 developed in public sector and a reputed commercial stock C-1 in the market were compared for the development of support and demand tissues and to assess their susceptibility to metabolic disturbances. Both were raised up to the age of five weeks on deep litter system under similar feeding and management practices. All measurements of support tissues (heart, lungs, liver, gizzard and intestines) and demand tissues (breast, drumsticks, thighs, back, wings and neck) were taken at 5 weeks of age. Birds of commercial stock C-1 were significantly heavier than PB-1.Weights of total support tissues (TOST) were higher in PB-1 (160.2g) than C-1 (155.4g), while weights of total demand tissues (TODT) and prime cut-up parts (PCP) were higher in C-1 (625.3g and 353.9g) than PB-1stock (580.4g and 331.8g). Because of low weight of support tissues and high weight of demand tissues, ratio of support to demand tissue was significantly lower in C-1 (0.249) than PB-1 broilers (0.279). It may be averred that PB-1 birds can better cope up with stressful conditions than C-1 and latter may be more prone to metabolic disturbances than PB-1 stock.
