The mean values of chemical components of bulk milk and of the calculated indices of technological suitability of raw milk: for butter and cheese production, were estimated. The obtained results allowed determination of an average chemical composition of raw milk, specific of the central Poland and its technological suitability, depending on feeding season, size of deliveries and quality class of the purchased raw milk.
