The article reports a case of acute copper sulfate (CuSO4) poisoning in 2-day-old turkeys. The first incidences were noticed 2 h after placing the animals in the poultry house, where turkeys were provided with wood shaving bedding. Post-mortem examination showed wood shavings present in gastric and intestinal contents and numerous lesions in the alimentary tract: dark green color of the koilin lining, and surface erosions, deep ulceration, and severe congestion of the gizzard. The copper (Cu) concentration in samples of the liver, kidney, heart, gizzard content, gizzard muscle, gizzard lining, and wood shavings from the bedding was determined. Our results showed that the level of Cu in the livers of affected birds was more than sevenfold higher than the recommended value and the Cu content in bedding material was above the value considered to be toxic to turkeys. Our investigation identified the bedding disinfected using a CuSO4 solution as a possible cause of turkey fatalities.
这篇文章报道了一例 2 日龄火鸡急性硫酸铜（CuSO4）中毒的病例。第一批病例是在将动物放入家禽舍后 2 小时发现的，火鸡提供了木屑床上用品。剖检显示胃和肠内容物中有木屑，消化道有许多病变：角质层呈深绿色，表面有侵蚀、深度溃疡和严重充血。肝脏、肾脏、心脏、肌胃内容物、肌胃肌肉、肌胃内膜和床上用品木屑中的铜（Cu）浓度进行了测定。我们的结果表明，患病鸟类肝脏中的 Cu 含量是推荐值的 7 倍以上，而床上用品材料中的 Cu 含量超过了对火鸡有毒的数值。我们的调查确定，使用 CuSO4 溶液消毒的床上用品可能是导致火鸡死亡的原因。
