OM digested in the rumen and OM digested in the total digestive tract were determined
for 12 forage types including the fresh form, silage and hay oflucerne (Medicago
sativa), red clover (Trifolium pratense) , orchard grass (Dactylis glomerata) and perennial ryegrass (Lolium perenne). Because of wet harvesting conditions red clover hay was substituted by red clover haylage, a baled wilted forage stored in sealed plastic wraps, with a dry matter content of about 500 g per kg forage.
