Six cases of nitrate poisoning in cattle are reported. The fact that the symptoms were highly acute and appeared as rapidly as within a few hours after feeding, was a striking feature in dairy cows. Deaths occurred among yearlings without the stock owners having previously noticed any changes. In those cases in which post-mortem studies were done, characteristic changes were not observed, with the exception of engorgement of the lungs with blood or paleness of the mucosae. Nitrate levels were found to vary markedly within a single lot of roughage. Early administration of methylene blue to reduce methaemoglobin and treatment with hypertensive agents may be life-saving.
本文报告了6例牛硝酸盐中毒病例。症状高度急性，且在喂食后短短几小时内就迅速出现，这在奶牛中是一个显著特征。一岁小牛出现死亡，而畜主此前并未注意到任何变化。在进行了尸检研究的病例中，除了肺部充血或黏膜苍白外，未观察到特征性变化。发现同一批粗饲料中的硝酸盐含量差异显著。早期给予亚甲蓝以降低高铁血红蛋白，并使用降压药物进行治疗可能挽救生命。
