A Holstein heifer calf approximately 1 month old has presented with mild hyperthermia and poor appetite for two days. The animal has a normal body condition and shows no respiratory or enteric symptoms. Inspection of the ventral abdominal wall reveals a slight protrusion of the residual umbilical cord, which is slightly hardened. Deep palpation of the intra-abdominal umbilical structures, although difficult due to abdominal wall muscle contracture, elicits a pain response and reinforces the suspicion of umbilical infection.
We decide to perform an ultrasound examination of the region to better identify the location and extent of the structures involved, in order to establish an accurate diagnosis and prognosis. After shaving the hair over the umbilical region, we apply alcohol to the skin to create optimal conditions for the ultrasound examination.
