Efficient grazing management requires anticipation and flexibility and would be greatly facilitated bythe development of dynamic tools with the capability to simulate different scenarios based on regularmeasurement of grass supply on the farm. Pastur’Plan, built on a spreadsheet within a partnershipbetween INRA and a livestock management advisory association (Orne Conseil Elevage), combinestwo complementary concepts. The first is inspired by the Grass Wedge method adapted to French grazingconditions to highlight the distribution and coherence of grass supply on the paddocks on a farm and therequirements for grass based on the grazing rules and objectives. The second concept allows us to describethe evolution of the balance between grass growth and demand according to various grazing simulationson a paddock-by-paddock basis. This paper describes the hypothesis and calculations implemented,and subsequently the simulation method used and the illustrations dedicated to help support decisionmakingby grazing managers.
