A study of cartilaginous nodules in the lungs of domestic poultry.
A high incidence of cartilaginous nodules was found in the lungs of broiler chickens. The incidence was higher in broilers fed ad libitum than in broilers fed a restricted amount of food. A much lower incidence of nodules was found in leghorn-type chickens, turkeys, ducks, and geese. It was theorized that the nodules may develop from embolic chondrocytes arising from abnormal cartilage, but no correlation could be found between lesions in the cartilage of the broilers and the presence of nodules in their lungs.
