Raising temperature from 40 to 50°C and acid concentration from 0.1 to 0.125N during 'pepsin' treatments given before the cellulase stage, increased digestion by 3 to 10% depending on the type of grass, up to the level reached by rumen liquor. For samples of brassicas (digestibilities ranging from 66 to 84%) milder pretreatment conditions were sufficient to give cellulase digestion values as high as rumen liquor estimates.  aCellulases  aDigestibility  aForage grasses  aPlant breeding  aDigestibilidade  aGramínea  aPlanta Forrageira1 aBORZUCKI, R.  tJournal of The Science of Food and Agriculturegv. 29, n. 3, p. 293-297, 1978.
