Silage made from young grass and which contained an average of 34.6 g nitrogen (N), 19.5 MJ gross energy (GE) and 271 g fibre/kg dry matter (DM), was found to have digestibility coefficients to sows of 0.73 for N, 0.60 for GE, 0.60 for cellulose and 0.51 for fibre. The addition of a cellulase enzyme preparation to the grass prior to ensilage decreased the fibre content by 38 g/kg DM and increased the water soluble carbohydrate (WSC) content by 154 g/kg DM, but did not influence the digestibility of the silage.
