Prairies multi-espèces et pâturage : analyse de l’aptitude de différents mélanges multi espèces à la poursuite du pâturage en période estivale

Abstract : The sector of cheeses under Protected Designation of Origin of Basse-Normandie faces a need of summer milk while breeders produce less milk, due to the drought of grasslands. In order to provide technical solutions, dairy farmers created a group: Groupement d’Intérêt Economique et Environnemental. They focus on boosting the production of milk by grazing multi-species grasslands during summer. The lack of local field experiences on multi-species grasslands grazed with dairy livestock, led breeders to sow their own tests. This study measures the yield, the nutritive value compared to plant association perennial ryegrass/white clover and does a botanic monitoring of those multi-species grasslands. This study shows that multi-species grasslands have an equivalent productive potential than the plant association: perennial ryegrass and white clover, after a two years trial. The continuation of the project over the subsequent four years would provide answers as the robustness of multi-species grasslands within dairy breeding in Basse-Normandie.
