| English abstract | The total and undegradable fractions of nitrogenous compounds associated to cell wall organic matrix in some tropical forages were evaluated. Samples of corn silage, elephantgrass silage and sugarcane were used. Neutral detergent insoluble nitrogenous compounds were divided in three different fractions associated with: hemicellulose (HN), cellulose (CN), and lignin (LN). The size of the different fractions varied among feeds. A portion of acid detergent insoluble nitrogen, which is the sum of CN and LN, was potentially degradable in the rumen. A portion of HN was not degradable in the rumen. The heterogeneous dimensions of degradable portion of all nitrogenous compounds among feeds can compromise the estimates of cell wall undegradable nitrogen by simple chemical approaches in tropical forages. The LN overestimated the lignin contents and the correction for those compounds on lignin has been suggested |
