      Four fattening systems were analyzed in terms of water use for feed production, drinking, cleaning and the parent stock. In all fattening systems the water input for feed production accounted for more than 90% of the total water input. For all fattening systems the water productivity was 0.3 kg carcass weight per m3 water input, 2.8 MJ food energy per m3 water input and 57 g food protein per m3 water input. The shorter fattening period and lower feed demand in the more intensive fattening systems were juxtaposed to the higher carcass weight and higher water productivity of the feed components in the more extensive systems.
