Controlled field trials with legume-cereal mixtures and monocultures were conducted on five Czech organic farms to determine the suitability for feeding ruminants. Mixtures of 60 % peas to 40 % cereals (wheat and barley) were compared with peas, wheat and barley monocultures. Our results show that for feeding beef cattle, it is most beneficial to harvest green matter in the BBCH 79 growth phase (green ripeness) which is characterized by high protein and energy concentrations and a low fiber concentration. The mixture of peas and barley was the most advantageous because the crude protein and NEL levels were the closest to the requirements for a balanced state between breakdown and synthesis in the rumen (CP 130 g/kg, NEL 5.9 MJ/kg DM). In conclusion, legume-cereal intercropping produces high quality feeds on organic farms.
