Precisely defining the water needs of pigs is of interest as concerns regarding water use of livestock increase along with manure management having rising costs. Diet consumption may impact voluntary water intake in swine. Increased water intake was noted when excessive dietary protein was fed, though reducing the crude protein does not reduce water intake. Other factors such as the water delivery system and the environment seem to be more relevant to water use by the pig.
