With the Universal Feeder’s saliva lick feeding system livestock use their tongue and saliva to draw feed out from between two plates.
When the animal’s tongue goes into the groove, the feed that sticks to their tongue is the ration that they can consume. The saliva decreases with progressive licks until the animal is unable to obtain any more feed.
Livestock will leave the feeder once they are unable to obtain more feed,enabling other animals to have their turn.
