The use of the cellulase digestion procedure for indexing the dry matter digestibility of forages.

The in vitro cellulase technique was compared with the rumen liquor technique and found to be more efficient for the indexing of the dry matter disappearance (DMD) of forages. A cellulase enzyme concentration of 80IU/gDM gave a satisfactory linear regression y = 1,3585x + 11,62540 (R2=0,6453;
