intestinal obstruction in the newborn due to the blocking of the bowels with thick meconium. This is an important disease of newborn colt foals. The syndrome is usually one of subacute abdominal pain, restlessness and straining, and a positive finding on rectal examination. Occasional cases show severe pain and tympany of the large intestine.
