This study assessed the effects of Irvingia gabonensis kernel powder (IKP) and Ocimum gratissimum leaf powder (OLP) dietary supplementation on performance of broiler chicken. A basal diet divided into four portions, designated diet 1 (the control) and diets 2, 3 and 4 supplemented with IKP, OLP and IKP+OLP composite mix 1:1 (IOCM), respectively. Two hundred and forty 1-day broiler chicks were randomly assigned to the four experimental diets (60 birds/diet; 10 birds per/replicate) using a Completely Randomised Design. At the finisher phase, the body weight gain and feed conversion ratio of the birds fed diets 2 and 4 were better (P <0.05) than those fed the diets 1 and 3. During the overall period, the body weight gain of birds fed diet 4 was similar to those fed diet 2 but higher than those fed diets 1 and 3, while the feed conversion ratio of birds in diets 2 and 4 was better (P <0.05) than those fed diets 1 and 3. The slaughtered and dressed weights of the birds fed diets 2 and 4 were significantly (P <0.05) better than those birds fed the diets 1 and 3. The dressing percentage of the birds fed diets 2 and 4 were higher (P <0.05) than those fed diet 1. White blood cells, granulocytes and lymphocytes counts were (P <0.05) higher in birds fed diet 4 compared to those on other diets. Serum cholesterol concentration and meat lipid peroxidation activities were significantly (P <0.05) lower in the birds fed diets 2, 3 and 4 compared to diet 1. The catalase concentration in the birds fed diets 3 and 4 were (P <0.05) higher than those chickens fed diet 1, while the glutathione peroxidase concentration in the birds fed the diets 2 and 4 were (P <0.05) higher than those fed diet 1. Glutathione concentration was higher (P <0.05) in meat from birds fed diets 2, 3 and 4, compared to the birds fed diet 1. The meat cholesterol concentration recorded in the birds fed diet 4 was comparable (P >0.05) to diets 2 and 3, but lower (P <0.05) than diet 1. The IKP and IOCM supplementation improved the growth performance of the broiler chickens. The overall health status and meat quality were also improved by the phytogenic supplements in this study.
