Abstract
|
|
|
|
A 5-month-old Holstein downer calf was presented, and bovine viral diarrhea virus was detected in the feces and the cerebrospinal fluid. Combined treatment of recombinant bovine somatotropin (rBST) administration and standing rehabilitation had been performed for two months, and the calf could maintain the standing position for a while. However, the symptoms were not improved, and the calf died due to ruminal tympany and aspiration pneumonia. Megaesophagus, abomasal ulcer, and a normal-sized but softened cerebellum were observed in clinical necropsy. Improvement of symptoms was confirmed by rBST, but was not reached the complete recovery of gait and standing position.
