How much water do pigs need?
As a general rule: Pigs will consume 1.5 to 2 times more water than feed.
Pigs lose water through four routes: 1. Kidneys (urination), 2. intestines (defecation), 3. lungs (respiration) and some through 4. evaporation (skin- sweat glands are largely dormant). Therefore, pigs must consume enough water to balance the amount of water lost. Care must be taken when determining water requirements for pigs, because true water usage is generally overestimated. Wastage is generally not taken into account, therefore realize there is a difference between water consumption and water disappearance (animal intake and waste).
Estimated water requirements of swine.
|Class of Pig||Gallons/pig/day|
|Nursery (up to 60 lbs.)||0.7 - 1|
|Grower (60 – 100 lbs.)||2 - 3|
|Finisher (100 – 250 lbs.)||3 - 5|
|Gestating Sows||3 - 6|
|Lactating Sows||3 - 7|
