This research conducted using a completely randomized design with 4 treatments, 4 replicate and 25 chicks each replicate. The experimental basal diets formulated according to Ross 308 manual and the peribiotic, probiotic and garlic powder was added to the basal diets as additives. The treatments were: basal diet (free of additives), 2- basal diet + 0.3% Fermacto, 3- basal diet + 0.3% primalac and 4- basal diet + 1% garlic powder. All chicks were fed with same corn-soybean meal based additive free starter diet from 1-10 d and then at grower (11-28 d) and finisher period (29-42 d) were fed the experimental diets. The diet containing Fermacto prebiotic significantly increased the daily weight gain of chicks. In grower phase the birds fed with garlic powder consumed more feed, but in the finisher phase the significant difference was observed on feed intake in birds fed with fermacto prebiotic. The best feed conversion ratio achieved in treatment containing prebiotic or probiotic and other groups. The economical comparison of each kg of body weight gain showed an increase in costs of diet with garlic powder or Primalac probiotic and a decrease in the cost per Kg of body weight gain in treatment containing Primalac prebiotic in comparison to the control group.
