This experiment was conducted in order to incite the spontaneous sucking behaviours of newborn piglets by two different artificial sucklers.One type of the sucklers was made of sponge with its surface warmed by warm circulating water through a rubber tube. Within 30 minutes after birth, 56.5% of the piglets successfully sucked from the suckler. The average time required for starting to suck was 17.8 minutes after birth. However, some piglets were found to suspend their nosing behaviour.The other suckler was made of a rubber bag containing warm water in it. The shaking movements of the bag by the contact of piglets stimulated the piglets for active nosing behaviour and 82.6% of them sucked from the suckler. The average time required for starting to suck was 10.3 minutes after birth.The artificial teats used in this experiment incited mouthing and sucking reflexes of newborn piglets. The teats were so structured as to allow milk to flow in a natural manner. When the piglets mouthed the teats, they could invariably initiate the sucking with no subsequent interruption.Stimulation of nosing behaviour and mouthing reflex of newborn piglets made it possible for them to suck the creep feed through the artificial sucklers.
