Abstract
Two components were associated with this research project. The first component
established and measured the water balance of a grower-finisher room in an intensive
swine operation (ISO) using dry and wet/dry feeders. The second component
verified various moisture production (MP) prediction equations for ISO's using
current MP values. Knowledge of the significant sources and sinks of water in an
ISO will allow future research on water conservation to focus on key areas.
Six separate grower-finisher cycles were followed and the parameters of the water
balance, including water from the drinkers, in the feed, metabolic reactions, within
the pig, ventilated from the room and in the slurry, were measured for each cycle.
The significant source of water was at the drinker, at 72% of the total water source,
and the major sink of water was in the slurry, at 64% of the total water sink. The use
of wet/dry feeders compared to dry feeders significantly reduced both the water
disappearance at the drinker by 34% (p
