The maximum exploitation of the productive capacity is possible through the adoption of food alternatives that allow the best use of the fodder at a lower cost. The apparent digestibility of sheep diets kept with multiple mix based on whole manioc scrap in place of maize was evaluated using five castrated Santa Inês male sheep, aged between four and five months, housed in individual cages. After adaptation, five experimental periods of 15 days were performed, totaling 75 days. The diet was composed of Tifton hay (cynodon spp) and multiple mixtures with inclusion levels of whole manioc scrap in place of maize, according to the treatments: Mineral Salt (SM), 0% (MM1), 33% ( MM2), 66% (MM3) and 100% (MM4). Excreta samples were collected to analyze the chemical composition. The digestibility parameters of the dry matter (DMS%), crude protein (DPB%) and neutral detergent fiber (DFDN%) were evaluated. There was no significant difference (p> 0.05) in dry matter and protein digestibility. The treatments T3 and T4 presented significantly (p <0.05) the best digestibility coefficients of the NDF. It is possible to recommend high levels of substitution of corn for whole-grain cassava in diets for sheep, being the choice based on cost and local availability.
