The determination of the solubility of the organic matter (OM) of hay in pepsin‐hydrochloric acid and fungal cellulase solution according to the method of Jones and Hayward 1 gave reproducible results when applied to four hays with solubilities of 51.5, 49.1, 63.5 and 40.2%. In addition the correlation of the soluble OM determined by the cellulase solubility technique and in vivo digestibility studies for 34 hays produced highly significant correlations for the digestibility of the OM in the dry matter (DM) ( r =0.91, RSD ± 2.180) and the OM digestibility ( r =0.91, RSD ± 2.362). These data indicate that the determination of the solubility of OM in fungal enzyme solution is an acceptable method for the prediction of in vivo digestibility of the OM in the DM of hays.
