Grazing systems for dairy cattle has the potential to be resource efficient for the farmer. However, increasing herd size can cause increasing problems with trampling damages on soil leading to claw problems and dirty udder, which costs working time for cleaning and risk of deteriorated animal health. Farmers ask for durable crop species and cost efficient investments. The aim of the project is to develop technical and agronomic solutions for long-term pasture management with a large dairy herd. The objectives are: 1) evaluate four seed mixtures concerning vegetation cover, botanical composition, production potential and feed value. 2) evaluate two materials used to protect areas exposed to a high degree of trampling in relation to investment costs. We are applying for a continuation as ongoing project has been implemented during two dryer seasons than normal. An evaluation of the robustness during more seasons with varying weather will produce results directly useful for the farmers.
