The staple food of the Montbéliardes cows of La Grange de la Haute Vallée consists of grass from the farm's 123.5 acres (50 ha) of meadow. It is supplemented with additional cereals and cakes, depending on the time of year. In summer, the cows directly graze green fodder made of grass, alfalfa, or rapeseed. In winter, they stay in the stables and feed on fodder previously harvested and stored dry, ensiled, or wrapped.
