Abstract

Outbreaks of gizzard erosion occuried in many flocks of young broiler chickens in Japan in 1978 and 1979. The lesions were identical to those caused experimentally by a diet containing 15% mackerel fish meal which was heated at 140°C for three hours. As a result, it was postulated that the naturally occurring cases were due to certain fish meals in the diets fed. The gizzard of young broiler chickens affected naturally and experimentally with the disorder was histopathologically examined. The initial gizzard lesions were widening and loosening of the lining with swelling of the chief and surface cells. With time, alterations of the lining became predominant, showing a trellis-like appearance containing many desquamated surface cells. Later, erosion and ulcer occurred in the depths of the fold. In these changes an excess secretion of the gizzard glands was noticed for the histopathogenesis.
