Microbial transfers from permanent grassland ecosystems to milk in dairy farms in the Comté cheese area
Abstract The specificity of dairy Protected Designation of Origin (PDO) products is related to their “terroir” of production. This relationship needs better understanding for efficient and sustainable productions preserving the agroecological equilibrium of agroecosystems, especially grasslands. Spe...
