Faba bean (Vicia faba L.), also called field bean, is rich in protein and energy. In particular, faba bean complements cereal well in the feed ration due to the high content of lysine. Faba bean can replace or supplement soya and can be used without further treatment. The crop can be sold to compound feed producers. But a better profit margin is achieved with on-farm use than when sold to the market. This note describes two practice cases where home-grown grain legumes are an important component of GMO-free feed rations.
