Cattle from 2 herds developed copper toxicosis after the ingestion of chicken litter. The affected animals were adult Holstein cows and crossbred steers that ate 9 to 16 kg of litter/day. These cattle developed a sudden onset of weakness, depression, anorexia, icteric mucous membranes, and dark reddish brown urine. Liver copper concentrations in 2 cattle (1 from each herd) were 436 and 730 ppm. Results of copper analyses of chicken litter ranged from 620 to 920 ppm. Sodium molybdate and sodium thiosulfate were added to the ration of the dairy herd. Two cows with clinical signs of copper toxicosis recovered after being given additional sodium molybdate and thiosulfate supplements, orally.
来自两个牛群的牛在摄入鸡粪后发生了铜中毒。受影响的动物为成年荷斯坦奶牛和杂交公牛，它们每天摄入9至16千克鸡粪。这些牛突然出现虚弱、抑郁、厌食、黏膜黄疸和深红褐色尿液。两头牛（每个牛群各一头）的肝脏铜浓度分别为436 ppm和730 ppm。鸡粪的铜分析结果在620至920 ppm之间。在奶牛群的日粮中添加了钼酸钠和硫代硫酸钠。两头有铜中毒临床症状的奶牛在口服额外的钼酸钠和硫代硫酸钠补充剂后康复。
