was adjusted to 1.0 to 1.4 L/min under a water pressure
of 41 to 48 kPa. Water disappearance was recorded at
0800 and 1600 daily. The water tanks were refilled after
each measurement of disappearance. Custom-fabricated
systems to collect wasted feed and water were
installed under the TriBar slatted floor of crates 7
through 12 in both farrowing rooms. Each crate had a
separate collection unit, which consisted of a screen, a
pan, and a carboy. The screen was set in the pan, and
the carboy was fitted under the pan. This allowed sepa-
ration of wasted water from the wasted feed for each
sow. Wasted water drained through the screen onto the
pan, where it then followed a designed slope into the
carboy. Collection units were mounted on garage door
tracks under the feeding and watering areas of the sow
beneath the crates.
Wasted feed was collected on a 1- to 3-d basis (0800)
