The effect of diets with different proportions of wet brewery residue on the nutrient intake and the weight gain of feedlot lambs in phase of termination were determined. An economic analysis of the food given to the animals was also performed. Twenty-five non-castrated Texel male lambs were randomly allotted into five groups, consisting in the replacement of the concentrate by wet brewery residue; at proportions of 0%, 25%, 50%, 75%, and 100%. The results of the test revealed a quadratic effect on the intake of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), and neutral detergent fiber (NDF); and a linear decreasing effect on intake of total carbohydrate (TCH), and non-structural carbohydrate (NSC), expressed in kg/day. The intakes of EE and NDF showed a linear increase and NSC intake showed a linear decrease, expressed in percentage of live weight (% LW) and g/kg LW.0.75 The consume of net energy (NE), daily weight gain, and feed cost showed a linear decrease with the increase in the proportion of wet brewery residue. It was not verified effect on profits related to the sales of the live animals or the sale of the carcasses.
