Pigs, Vitamin A deficiencies.
First Page Number
Last Page Number
VARYING degrees of Vitamin A deficiency are often seen in pigs which do not have regular access to fresh green feed and do not have a special Vitamin A supplement added to their feed. The deficiency may show itself as failure of the sows to come into season, the birth of dead and malformed piglets, or the birth of weak piglets which die soon after birth. Those Vitamin A deficient piglets which do survive are very susceptible to infectious diseases and often show varying degrees of paralysis. Boars kept on a diet deficient in Vitamin A become infertile.
