Summary
The water intake of pigs is not well known since a large amount of water is wasted from drinkers. A study was conducted to determine water intake and wastage by grower/finisher pigs at nipple drinkers. Actual water intakes of growing and finishing pigs are 4.0 and 5.9 l/d, respectively. The pigs wasted 25% of the water flowing from the nipple drinkers. High nipple flow rates increase water spillage of pigs.

Introduction
Among nutrients, water is required in the greatest amount but has received the least attention. Water intake of grower/finisher pigs has been reported to range from 1.9 to 6.8 l/d, depending on body weight and feed intake. However, most a
