Diagnosis of various teat lesions in dairy cows by ultrasonography

Abstract

In this study, 62 teats obtained from slaughtered cows and 51 teats obtained from live cows were compared by ultrasonography and classic clinical examination methods. After examining by classic clinical examination methods, all teats were examined using B-mode ultrasound equipment, with a 5 MHz linear array transducer. When compared with classic clinical examination methods, ultrasonographic examination more readily detected stenosis, obstruction and other anomalies in all parts of the teats except for those in the ductus papillaris. Ultrasonographic examination was also beneficial for the determination of the shape and size of the stenosis, obstruction and other anomalies of the teats.
