In organic dairy production there is a great need for locally produced protein crops as a complement to clover/grass-silage. Increased cropping of intermediate crops as an alternative to cereals is also very desirable. High quality clover/grass-silage is a prerequisite to increased use of locally produced protein/starch crops, for instance field beans. Thus, the possibility of high-yielding dairy cows meeting their feed requirements on 100% organic feeds, e.g. field beans, and ways in which field beans could be most effectively used in dairy cow production need to be further investigated.
