The aims of the experiments conducted at the INRAE-Herbipôle research farms deal with ruminant farming systems in grassland mountain areas, in connection with products qualities (meat, milk and cheeses) and environmental impacts (e.g. biodiversity, carbon fluxes). “Herbipôle” (Marcenat-Laqueuille) is located in grassland mountains from 1000 to 1400 m a.s.l. For Marcenat-Laqueuille installation, the total area is near 1000 ha of various types of permanent grassland (90 %) and sown pastures (10 %). The installation hosts dairy (160 Holstein and Montbéliarde) and beef (160 Charolais, Salers, Salers x Angus) cows and conducts long-term studies on adaptive capacities of dairy and beef cows in low-inputs grass-based systems..
