The food industry had a substantial increase in the consumption rates of chicken meat and added to the economic misfortune in question the value of feed raw material, which was already considerably high, exceeds rates never seen by producers, leading to the search for alternative foods that are equivalent to the nutritional value of corn and soybean meal. Brewery waste is a by-product of the brewing industry with potential for inclusion in animal feed and with abundant supply. Thus, the study was conducted with the objective of evaluating brewery waste in diets for slow growing broilers. A total of 400-day-old chicks of the Naked Neck strain were used, distributed in an entirely randomized design, with five treatments and 16 birds each. The inclusion levels of brewery waste in the diets were: 0; 2.5; 5.0; 7.5 and 10%. The zootechnical performance and the carcass characteristics of broilers from 1 to 84 days of age were determined. There was no significant effect among the levels studied for weight gain, feed consumption and feed conversion. For carcass yield, cuts and relative weight of organs there were also no differences between inclusion levels. However, for the analysis of body fat deposition there was a significant difference, indicating that the inclusion of 2.5% presents a maximum level of fat deposition, with a reduction at the inclusion of 10%. In this sense it is indicated that the inclusion of 10% can be adhered to the diet without causing deficits in performance and yield of cuts in slow growing broilers.
