Conteúdo: 	Abstract: In order to evaluate the effects of a symbiotic on 1?42-d-old broiler chicks, performance and carcass yield (CY), as well as litter concentrations of phosphorus and nitrogen were measured in a trial using 640 male chicks (Cobb 500). Birds were randomly distributed into 4 treatments with 8 replicates (pens) of 20 birds each. The treatments were different levels of the symbiotic (probiotic bacteria, exogenous enzymes, and autolyzed yeast) in the diets: 0.0, 0.5, 1.0, and 1.5 kg/t, and regression analysis using orthogonal polynomial contrasts was performed. As a challenge, it simulated conditions of commercial broilers sheds. The symbiotic provides beneficial effects for the animal?s performance, especially weight gain, which increased 4.3%, in the treatment with 1.5 kg/t inclusion compared with the diet without symbiotic. Inclusion of the symbiotic in the diets provided improvements in CY and breast yield. The data suggested that the tested symbiotic is a good tool for enhancing poultry performance through nutrition
