Resumo
This experiment evaluated the nutritional
composition of rice straw submitted to the different urea
doses and water, by using a completely randomized experimental
design in factorial combination of 20, 30 and 40% of
water and 2, 4 and 6% of urea fertilizer on basis of the dry
matter. Significant interaction was verified (P <0.05) among
water and urea added for medium crude protein content. By
the addition of 4 and 6% of urea and 20, 30% of moisture
reduced (P <0.05) in the NDF (neutral fibber in detergent)
content. It was observed that 4 and 6% of urea and 40% of
water reduced the of ADF (acid fibber detergent) contents.
Highest hemicelulose reductions were observed with the
interaction (P <0.05) of 2 and 4% of urea with 20 and 30% of
water. The addition of 4% of urea and 30% of water increased
the CP (crude protein) content, and provided highest
reductions on the ADF, NDF and hemicelulose contents of
the rice straw.
