Green protein from clover-grass or alfalfa is considered a valuable protein source for poultry and pigs. By concentrating the protein fraction from grass clover crops grown locally in Denmark, and by using biorefining technology, one expects to obtain a vegetable protein and amino acid source that can optimize feed formulation of organic layer and pig diets, thereby increasing the sustainability of organic egg and pig meat production as well as increase feed efficiency. Optimisation of the biorefining method is a continuing process, and recent studies have shown that the protein and amino acid content increased from 2016 to 2018. Target groups are organic farmers, advisors, industry and scientists.
