A total of 192 day-old broiler (Vencobb-430Y) chicks were uniformly distributed into four treatment groups with 48 birds per treatment for a period of 42 days. The dietary treatments were T₁: Basal diet (BIS, 2007), T₂: Basal diet + 0.5%, T₃: Basal diet + 1.0% and T₄: Basal diet + 2.0% of papaya (Carica papaya) leaves powder was supplemented. The carcass characteristics and haemato-biochemical parameters were studied at the end of the experiment. Results revealed that there was no effect (p>0.05) on dressed weight and percentage in broiler chickens. Papaya leaves powder supplementation had no effect (p>0.05) on liver, heart, gizzard, kidney and spleen weights of broiler chickens. Papaya leaves powder supplementation did not influence haemoglobin and haematocrit concentrations in broiler chickens. There was significantly lower glucose, cholesterol and SGOT concentrations were observed in the T₄ group as compared to the T₁ group. The serum total protein concentrations in broiler chickens were significantly higher in T₃ group. The serum triglyceride concentrations were significantly (p<0.05) higher in T₄ group as compared to other treatment groups. It could be concluded that papaya leaves powder supplementation at the dose rate of 0.5, 1.0 and 2.0% in the feed had no effect on carcass characteristics and haemato-biochemical profile of broiler chickens. The papaya leaves powder supplementation at the dose rate of 1.0 and 2.0% in the feed significantly lowered serum glucose, cholesterol and SGOT levels, whereas, total protein and triglycerides levels increased in broiler chickens.
