A Peculiar Nutritional Dermatitis in Pigs

Abstract

IN the course of our advisory duties, we have frequently encountered a number of cases of a peculiar dermatitis in pigs. The condition develops in pigs of about 10–12 weeks of age and is characterized initially by the development of red blotches under the skin of the hocks, spreading up the hind legs into the groin and over the belly and eventually over the back and ears. The dermatitis is accompanied by an acute irritation ; the pigs become very uncomfortable and rub continually against the sides of the sties. This rubbing usually breaks the skin, resulting in the formation of extensive scabs. Appetite is adversely affected and the pigs make little or no live-weight gain. Natural recovery is very slow, and as a result of the condition, the pigs may take several weeks longer to reach the bacon factory.
