An experiment was carried out with female broilers, aiming to evaluate the effect of usingprobiotics and symbiotics on growth performance and yield of carcasses and of the main commercial cutsand edible viscera. A total of 720 one-day-old Cobb chicks, distributed in a completely randomizedexperimental design with four treatments and six replicates of 30 birds each at a stocking density of 10 birdsper square meter (m2). At 42 days old two broilers of each experimental unit were sacrificed to evaluate thecarcass yield and its parts. The carcass yield was not affected by the inclusion of probiotics and symbioticsin the diet being equivalent to the antibiotic group. No significant difference was observed among thetreatments, even in the controls that did not receive any additive factor. All the performance parameterswere similar for the four treatments, with the exception of weight gain, that was significantly lower inprobiotic treatment. It was concluded that these additives are important alternative to replace antibiotics asgrowth enhancers, which have already been banned in many countries.
