The objective was to evaluate effects of extruded soybean hulls as replacement for corn silage. Twenty animals with an average weight of 57.00kg were used. The treatments consisted different levels inclusion the extruded roughage to replace the silage. A completely randomized design was used. There was negative linear response for dry matter intake, weight of feces in dry matter, efficiency ingestion, chewing and rumination and urea. Dry matter digestibility showed a quadratic response. The time spent in chewing and rumination increased with the addition of corn silage. The replacement of corn silage by extruded roughage can be performed in up to 80% without causing any deleterious effects to adult sheep.
