摘要

A 19-month-old Korean native cow died the following day after consuming new silage. Grossly, the liver showed enlargement, redness, and haemorrhages in all the lobes. Additionally, many of the bur-shaped fruits of the cocklebur (Xanthium strumarium) were found in the gastric contents. The histological evaluation confirmed centrilobular hepatic necrosis. Additionally, carboxyatractyloside (CATR), a material fatal to animals found in the cocklebur, was detected in the gastric contents using high-performance liquid chromatography-quadrupoletime of flight mass spectrometry (HPLC-Q-TOF-MS). Based on the pathological findings and analytical confirmation, CATR intoxication was diagnosed. Therefore, careful feeding and elimination of the cocklebur is essential for minimising economic loss.
