National audienceSeventy-six dairy farms composed of high-producing (6200 to 8800 kg/yr) Montbéliarde cows that were fed hay-based rations were included in a detailed survey involving the herd and the farm structure, quality of forage, winter and summer feeding practices, and genetic characteristics (breeding value and herd effect for milk production, fat concentration, and protein concentration). These data permitted analysis of the variations of milk composition among farms. The mean annual fat and protein concentrations varied greatly among farms in spite of the homogeneity of the farm sample with regard to milk produced, breed, and type of winter roughage. Such variability results essentially from environmental factors. When farms were ...
