Abstract

Granuloma-like swelling developed on the outer surface of the hock joint of heavy breeds of broilers reared in wire cages. The lesions was bilateral and was commonly ulcerated. It caused severe deformity of the legs. Histopathologically, the lesion consisted of highly cellular and highly vascular granulation tissue. Chickens developed this lesions sitting on their breast on cage wire for long peroids. Constant trauma by the wire has led to the development of fibrocysts or granuloma-like lesion between the epidermis and the muscular tissues on the keel bone. The internal organs were not significantly affected by these lesions but three birds died from dehydration nad debility.
