The objective of this study was to evaluate the chemical composition, pH and rumen degradability of banana tree pseudostems pre-dried and ammoniated with different doses of urea (0, 0.5, 1.0, 1.5 and 2.0% in natural matter). The experiment consisted of five treatments (doses of urea) with six replications, following a completely randomized design. There was a linear increase in the pH (P < 0.01) of the banana tree pseudostems pre dried with the inclusion of urea. There was no difference (P > 0.05) in dry matter, ash, neutral detergent fiber, acid detergent fiber, lignin, non-fibrous carbohydrates and total digestible nutrients; the averages were 31.58, 18.82, 46.43, 9.30, 11.87 and 42.52%, respectively. The inclusion of 2% urea increased the crude protein content (P < 0.01) by 42.75%, the soluble fraction "a" by 31.82%, and the potential and effective degradability of dry matter by 15.49% compared to that of the control group (without urea). The potentially degradable fraction, time of colonization and ruminal repletion of the neutral detergent fiber of the pre-dried banana tree pseudostems were not altered with the inclusion of urea (P > 0.05). The ammonization of the pre-dried banana tree pseudostems with 2% of urea improved the chemical composition and rumen degradability of the dry matter.
