This experiment was conducted to evaluate the replacement of the olaquindox as growth promoter for a probiotic, based on Bacillus subtillis, in broiler rations from 1 to 43 days of age. The evaluation was in terms of performance, nutrient digestibility and metabolically energy values of rations. A total of 930 AG-Ross 508 chicks were distributed in 15 boxes, at the density of 11 birds/m2. The broilers were allotted in a completely randomized design with three treatments and five replications, each with 62 birds. The treatments were defined as: Treatment A (diet with olaquindox and without probiotic), Treatment B (diet without olaquindox and without probiotic), Treatment C (diet without olaquindox and with probiotic). No effect was observed (p >0.05) in nutrient digestibility and in metabolizable energy for rations containing these additives. The performance results of broilers treated with olaquindox did not differ (p >0.05) from those treated with probiotic. The probiotic can replace olaquindox in broiler rations without effect on broiler performance or digestibility
