RESUMO
A disease in broiler chickens associated with rickets-like symptoms observed on post-mortem examination is described. The disease is not caused by deficiencies in the feed. Treatment with vitamin D3, calcium and phosphorus has little if any effect. There is evidence to suggest a relationship with the origin of the broilers. It also is an established fact that the disease is related to the farm. Particularly those broilers will develop rickets-like symptoms, which were housed on litter previously used for chickens with the same disease. It probably is an infectious disease. Non-purulent inflammation of the glandular stomach is constantly observed in chickens showing rickets-like symptoms. This disease is transmissible to SPF chickens. It is not clear whether this is an accidental finding or typical of this clinical picture.
