SUMMARY Twenty samples of forages and byproducts were analysed for NDF and ADF, using a simplified version of ANKOM procedure utilizing a poliester bag (PBT) and the method of Van Soest (VST). The values of determination coeficient (R2 ) were 0.74 and 0.73 for NDF and ADF respectively. The average values obtained with both methods ranged from 64.67 to 65.22 p.100 for NDF and from 54.54 to 45.33 p.100 for ADF. No significant differences were found between PBT and VST for NDF, but for ADF they were significant (p
