Water is the largest single component of the pig's body (up to 90% of the baby pig). Quantitatively, it is required by the pig in amounts larger than any other nutrient. Water functions as a critical component of the pig's body, is essential for metabolism, and is the primary factor in body temperature control. Pigs usually consume 2 to 3 lbs. of water for every pound of feed consumed. If water is not readily accessible to the pig, if the pig is overcrowded, or if an adequate number of waterers are unavailable per pig, feed intake and subsequent daily gains will be reduced.
