This experiment was conducted in order to evaluate the effect of two levels of soybean hulls (SH) and three sources of nitrogen on the ingestion of dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), non fiber carbohydrates (NFC) and acid detergent insoluble protein (ADIP), in steers. Six Holstein x Zebu steers, with 12 months of age and 229 kg of live weight, rumen fistulated, were used. The animals were distributed in six treatments in a 6 x 6 Latin square design. They were individually fed allowing 10% DM leftover. The nitrogen sources did not influence the ingestion of DM, OM, CP, NDF and ADF. However, it was observed greater ingestion of NFC when animals were fed with starea than when they received “avian slaughter byproducts flour”. It was concluded that the soybean hulls can partially substitute the roughage fraction of bovine ration, and that the starea can totally substitute the soybean meal without detriment in the ingestion of the studied nutritional components.
