A research project, 'Grünlegum', has found that drought and the need for high-quality protein feed can be addressed by using alfalfa and red clover as forage plants. The project has identified that the leaves of these plants, when separated from the stems, can be used in pig feed with a protein concentration of over 30% in dry matter. The timing and weather conditions of harvest are also crucial. The Bavarian State Agency for Agriculture is now starting a new project, 'NovaLuz', to develop an innovative protein product from alfalfa.
