“…Therefore, this approach must be utilized with caution, and it is preferable, when feasible, that the estimate of the UNDIP be obtained by biological method, i.e., through the evaluation of the residual CP of the iNDF estimated by long-term in situ procedures, followed by treatment of the sample with neutral detergent fiber for the removal of microbial debris (Clipes et al, 2010a;Detmann et al, 2010b).…”

“…According to Gomes et al (2011), none of the different methods employed at the evaluation of lignin fully meets the nutritional expectation, with significant differences in the results obtained in laboratories for all the methods applied. Stronger correlations between lignin contents and extent of the rumen degradation of the NDF have been obtained by methods distinct from the one adopted by the NRC (2001) and suggested by Detmann et al (2010a) (Traxler et al, 1998;Clipes et al, 2010b;Gomes et al, 2011). This seems to indicate that limitations intrinsic of the lignin content estimated by the method of acid hydrolysis may reduce the accuracy of estimates of the pdNDF and iNDF fractions by chemical approach.…”

“…In the case of crude fiber, the foods are first submitted to digestion with diluted acid and then to digestion with diluted base (alkali). The remaining portion after the two digests is named crude fiber, then considered as the portion of the indigestible carbohydrates by the animal (Detmann et al 2010;Silva and Queiroz, 2002). As the majority of fiber sources consumed by the animals are from a vegetable source, the definition of crude fiber basically covers the fibers of vegetal origin: cellulose and alkali-insoluble lignin (Silva and Queiroz, 2002).…”
