Abstract
Bovine respiratory disease is regarded as a serious veterinary problem because it can be costly to identify, treat, and monitor, resulting in significant financial losses in the herd. The study was carried out to identify the most important clinical signs and determine the type and severity of lung lesions using ultrasonography. Twenty local cow breeds, aged 3 to 8 years, were used in the current study. A case history was obtained, clinical signs were recorded on a clinical card, and the lungs were examined firstly by auscultation using a stethoscope, and then ultrasound evaluation was carried out using a portable KX5100 vet ultrasound machine with a 3.5 MHz curved probe. Clinical examination indicated that all cows had coughed, while 85%, 80%, and 70% of the cows had lacrimation, nasal discharge, and fever, respectively. According to an ultrasound of the lungs, 60% of the lesions were acute and 40% were chronic. The most common lesions in acute cases were irregular pleural surface (89%), comet tail artifact (71%), and abnormal alveologram (65%). In 40% of cases, chronic lung consolidation lesions were also observed. Ultrasound is very effective at detecting lung lesions. By using ultrasound imaging, it is possible to distinguish between acute and chronic lung lesions in cows..
