This experiment was developed to evaluate the effect of the urea addition on the nutritional value of the Tanzânia-grass hay (Panicum maximum, Jacq cv. Tanzânia). The experimental design was entirely randomized, with four treatments: T1 – only hay, T2 – hay with 1.0% of urea, T3 – hay with 2.0% of urea and T4 – hay with 3.0% of urea, with base in the dry matter, and ten replicates per treatment. There was positive linear effect of the urea levels on the crude protein (CP), being the largest level providing increases of four percentile points in relation to the control treatment. This treatment provided, also, reduction in neutral detergent fiber (NDF), acid detergent fiber (ADF) and hemicelulose (HEM), through a negative lineal effect. The values obtained by the regression equation in the highest dose were 62.37, 38.74 and 23.66%, to NDF, ADF and HEM values, respectively. There was positive linear effect for the digestibility with the addition of the urea levels providing medium increases of 53.93% in the control to 63.96% in the dose of 3.0%. The urea use is efficient in promoting increment in the quality of the Tanzânia-grass hay.
