A 3-month-old Holstein heifer calf was presented because of an abnormal gait. Further examination revealed cranial nerve deficits, including a severely delayed corneal reflex. The calf was not ataxic and maintained an appetite, but was considerably stunted for her age. A postmortem examination resulted in a diagnosis of a congenital portosystemic shunt.
