Use of Rapid Thoracic Ultrasonography for Detection of Subclinical and Clinical Pneumonia in Dairy Calves

Detection of subclinical disease has become the focus of much research in the recent past, e.g. mastitis and ketosis in dairy cattle, and pneumonia secondary to Rhodococcus equi infection in foals. The purpose of this study was to assess, using thoracic ultrasonography, the prevalence of abnormal lungs in pre-weaned dairy calves. Subsequent objectives were to describe ultrasonographic changes within the lung, respiratory score, and treatment of respiratory disease.
