【 摘 要 】

This study reports on two Hanwoo (a native Korean breed of cattle) calves, a 3- and6-month-old presenting with diarrhea, anorexia and blindness. Ophthalmoscopic examinationrevealed bilateral papilledema in both calves. Reverse-transcription polymerase chainreaction tests for bovine viral diarrhea virus, rotavirus and coronavirus were allnegative. The levels of serum vitamin A in the two affected calves were 0.317µg/dl and 0.481µg/dl, respectively. These values are much lower thanthe normal vitamin A levels; therefore, the calves were diagnosed with hypovitaminosisA.
