The project aims to broaden the too narrow crop rotation in dairy/maize regions by introducing shredded cereals whether or not in mixed cultivation with leguminous plants. This with a view to maintaining or improving organic soil carbon, less use of crop protection products and fertilizers and more biodiversity. Via incorporation of these shredded cereals in dairy rations, the project also aims to achieve a better balance between high milk production and animal health by reducing the occurrence of subclinical rumenacidosis. This optimization will lead to an improvement of the economic return of the dairy farms through saved cultivation, feed and livestock costs.
