The incidence of ectopic cartilaginous and osseous lung nodules in young broiler fowls with ascites and various other diseases.
The incidence of ectopic cartilaginous and osseous lung nodules in young broiler fowls with ascites and various other diseases has been determined. In all groups of diseased birds there were more nodules in the lungs compared with control birds. The birds that died with an ascitic syndrome had a significantly greater number of nodules than the other groups of diseased birds, with significantly more occurring in the left lung than in the right (P<0.001). Histologically, the fibrous cartilaginous type of nodule was the most numerous and the osseous type the least numerous. This is the first detailed study in fowls in which a relationship has been demonstrated between the presence of cartilaginous and osseous lung nodules and various disease states.
