Intake and digestibility of Acacia glomerosa (A) and Leucaena leucocephala (L), mixed with ammoniated rice straw (ARS) and maize by-product flour (CB) was evaluated for growing goats. Eight goats were used (21 kg average liveweight). A factorial arrangement 2×2, in Latin square design was conducted. The factors were 2 vegetal species and 2 inclusion levels. The study was conducted in 56 days. The cell wall intake (NDF) was superior for A vs L (652.13 vs 535.3 g/goat/day). Digestibility of organic matter (OM) was superior for A vs L (79.83 vs 71.37%). The same occurred with: NDF (83.19 vs 76.85%) and acid detergent fibre (ADF) (81.82 vs 67.39%). Higher intake of dry matter (DM) occurred at the smallest inclusion level (18.75%). Further, the low inclusion level showed higher digestibility of DM, OM, NDF and ADF than the high inclusion level.
