O consumo e a digestibilidade aparente dos nutrientes foram determinados em ovinos confinados, objetivando avaliar a
combinação do resÃduo desidratado de vitivinÃcolas a diferentes fontes energéticas. Foram utilizados dezoito ovinos não castrados,
com idade aproximada de sete meses e 21 kg de peso vivo, distribuÃdos num delineamento em blocos casualizados com três
tratamentos e seis repetições. As dietas foram compostas de 50% de resÃduo de vitivinÃcolas e 50% de concentrados energéticos: grão
de milho moÃdo (Zea mays L.) (T1), raspa de mandioca (Manihot esculenta Crantz) enriquecida com 1,8% de uréia (T2) e farelo de
palma forrageira (Opuntia fÃcus-indica L.) enriquecido com 1,1% de uréia (T3). As maiores ingestões foram observadas para as
combinações de resÃduo com grão de milho moÃdo e resÃduo com farelo de palma, respectivamente, com valores para a matéria seca de
84,34 e 107,37 g/PV0,75/dia/animal, proteÃna bruta 133 e 160 g/dia/animal e NDT 461 e 497 g/dia/animal. As digestibilidades da matéria
seca, proteÃna bruta e fibra em detergente neutro foram de 52,89, 47,12 e 42,37; 54,36, 49,63 e 54,95; 36,96, 34,22 e 32,82 %,
respectivamente para as dietas com grão de milho, raspa de mandioca e farelo de palma. Os resultados obtidos para o consumo e para
a digestibilidade aparente dos nutrientes, revelaram um bom potencial do resÃduo de vitivinÃcolas combinado as fontes energéticas
estudadas.
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.
