The enzymatic degradability (Method B, HCL 0.1 N) allowed a more accurate prediction of the in vivo organic matter digestibility (OMD) of 24 feeds than the separate data of crude fibre, neutral detergent fibre (NFD), acid detergent fibre (ADF) and acid detergent lignin (ADL) contents or in vitro digestibility. The selected equation obtained with the cellulase method could also be used for feed mixtures.  adigestibility  aforage  anutrition  aDigestibilidade  aMatéria Orgânica  aNutrição  aPlanta Forrageira  aDry matter1 aMICHALET-DOREAU, B.  tAnimal Feed Science and Technologygv.20, p.203-218, 1988.
