A system for supplying heated milk or other liquids to individual drinkers from
which animals, particularly baby pigs, can drink on a need basis by actuating a
valve in the drinker that allows the milk to flow into the drinker. The system
has a plurality of drinkers within a closed system in which the milk is supplied
from a reservoir, heated to a minimum predetermined temperature range and pumped
to each drinker which is positioned so that milk is continuously circulated through
the drinker any time the circulating pump is running. This not only keeps the heated
milk from spoiling, but it also prevents the drinkers from becoming clogged and
permits the entire system to be cleaned in place.
