To determine crude fibre (CF), NDF, ADF and ADL, the conventional technique (CT), using filter crucibles, was compared with the filter bag technique (FBT). The mean CF content of 56 forages and concentrates was slightly, but significantly lower (P-amylase solution, equally spread over the digestion and the first two rinsing periods. For ADF of 11 feeds the correlation between the two techniques improved from 0.993 to 0.997 when 0.5 instead of 1.0 g sample was incubated and repeatability was clearly better for the FBT. For ADL of 12 feeds, after sequential analysis of NDF and ADF, the FBT showed excellent precision and no significant difference with the CT.
