Intrinsic properties of plant cell walls determine the digestibility of ruminant diets, as they establish the maximum degree of the rate and extent of cell wall digestion in ruminants. The determination of INDF is important for the estimation of potentially digestible NDF (DNDF), and has been shown to be a suitable parameter in prediction models of energy and protein values in feedstuffs for ruminants, as the NorFor system. Therefore, there is a need to develop laboratory methods, applicable in practice, that determine the INDF content in feedstuffs. The present paper aims at presenting correlations and ratios between INDF and related measurements as lignin (ADL) and organic matter digestibility (OMD), for evaluating the ability of these feed variables to predict the INDF concentration.
