To evaluate the diet combination of the dried winery residue with different energy sources, intake and apparent digestibility were determined in feedlot sheep. Eighteen male sheep with seven months of age, non-defined breed, weighting initially 21 kg, were used, distributed in a randomized blocks design with three treatments and six replication. The diets were composed with 50% of dried grapes residue and 50% of energetic concentrate: corn meal (Zea mays L.) (T1), cassava meal (Manihot esculenta Crantz) enriched with 1,8% of urea (T2) and cactus meal (Opuntia ficus-indica L.) enriched with 1,1% of urea (T3). The greatest intake were observed in the combinations of dried winery residue with corn meal and cactus meal and the dry matter intake were, respectively, 84,34 and 107,37 g/PV0,75/day; crude protein intake were 133 and 160 g/day and TDN were 461 and 497 g/day. The dry matter, crude protein and neutral detergent fiber digestibility coefficients were 52.89, 47.12 and 42.37; 54.36, 49.63 and 54.95; 36.96, 34.22 and 32,82%, respectively, for the corn meal diet, cassava meal and cactus meal. The results for the intake and digestibility coefficients revealed that dried winery residue has good potential to be used to feed sheep in combination with different energy sources.
