This study evaluated the effect of supplementation of three different feed additives which included phytogenic premix, probiotics and multienzymes in a maize based diet in broiler chicken production. The study evaluated the different feed additives on growth performance, nutrient digestibility and economics of production of 120 unsexed one-day-old broiler chicks. The chicks were randomly divided into four groups with thirty chicks in each group in a completely randomized design. Feed and water were provided ad libitum and the quantity of feed intake and weekly weight gain were recorded weekly. The groups are the control group, phytogenic premix group, probiotics groups and multienzyme group. Groups fed the different feed additives reflected significantly (P<0.05) higher body weight and improved feed conversion ratio than group not supplemented with a feed additive. In comparison to the control group, the phytogenic premix, probiotics and multienzyme groups improved (P<0.05) dry matter, crude protein and crude fibre digestibility. The result of economics of production showed that birds fed the diets supplemented with probiotics and multienzyme was 8.90% more efficient than the group fed diets without feed additives and group fed diets supplemented with phytogenic premix was 7.76% more efficient compared with the control group. Based on the result obtained in the present study, it can be concluded that by using non-antibiotic feed additive in the diets of broiler chickens, phytogenic premix, probiotics and multienzymes are recommended in view of improved growth performance, nutrient digestibility and good economical return in the broiler production.
