The terms of chemical composition, total digestible nutrient, in vitro dry matter digestibility and in vitro gas production technique of plant components: steam base and braird and sisal co-products: SC (in natura, ammonization, and hay) and beater powder were evaluated. The experimental design was completely randomized with three replications. The dry matter values were 11.4% for silage and 89.7% for hay. Sisal co product ammonized with 5% urea present high values of CP, 22.7% and braird, 10.5%. The steam base and beater powder do not present values for ether extract. The steam base and braird present high values for nonfiber carbohydrates, 72.7 and 69.5%, respectively. There were no significant differences for IVDMD. The acid detergent fiber, neutral detergent fiber, and PCG values of braird, beater powder and steam base characterize as roughages with high fiber digestibility.
