title: An intermittent problem with tibial dyschondroplasia.
abstract: Broilers observed in the summer of 1978 had an excessively high incidence of tibial dyschondroplasia, causing both downgrading and loss of parts from broken legs. No etiological agent was determined. Birds held to 16 weeks of age retained the cartilaginous lesions. Bone ash was not diagnostic. Serology indicated no correlation with infectious bursal disease. No bacteria were isolated. The condition was not observed in the next placement of chicks.
