Fibrolytic enzymes have been added

Fibrolytic enzymes have been added to forage and
ruminant diets to improve forage digestibility and animal
performance, respectively. Enzyme application to
forage immediately before in vitro incubation improved
digestion of DM and NDF (Feng et al., 1996) suggesting
that applying fibrolytic enzymes at or just before feeding
may enhance digestion of forage by cattle
