The aim of this study was to determine the effect of dietary supplementation of Carica papaya essential oil (CPEO) on the growth performance and carcass characteristics of broiler chickens. 200 1-day Cobb 500 chicks of mixed sex were used for the seven weeks trials. In a completely randomized design 100 birds were randomly distributed into 4 groups consisting of 10 birds. Each treatment group has 5 replicates, birds in group 1 (G1) was fed basal diet with no Carica papaya essential oil, G2, G3 and G4 were fed basal diet with 100 mg, 200 mg and 300 mg/kg respectively. Clean water was supplied ad libitum. Results on overall growth performance revealed that average daily weight gain, average daily feed intake were higher (P˂0.05) in G2, G3 and G4 relative to G1. Mortality and feed conversion ratio were significantly (P˂0.05) influenced by dietary supplementation of CPEO. Higher mortality was observed in G1 while none was recorded in other treatments (P˂0.05). Dressed weight, eviscerated weight and dressing percentage were higher (P˂0.05) in G2, G3 and G4 than in other treatment group. Weight of legs, heart, spleen, gizzard, thigh, breast, back, drum stick and neck were significantly (P˂0.05) different among the groups except for the weights of the head, spleen and livers (P˃0.05). It was concluded that CPEO can be supplemented up to 300 mg/kg in the diets of broilers without negatively affecting their general performance and health status.
