初产分娩奶牛丙二醇中毒病例分析

Case Analysis of Propylene Glycol Poisoning in the First Generation of Dairy Cows

奶牛饲料中添加丙二醇可减少肝脏脂肪的沉积,改善奶牛的繁殖性能,并且可有效预防奶牛酮病。如果添加量超出合理范围将会发生丙二醇慢性中毒。2016年12月,黑龙江八一农垦大学动物医院接收2头病牛,根据临床症状结合血常规及血液中葡萄糖、游离脂肪酸、β-羟丁酸等一系列检测结果后确诊为丙二醇慢性中毒。本文对丙二醇慢性中毒临床症状、血液指标、生化指标及丙二醇对奶牛机体的副作用进行了分析探讨。

Feeding propylene glycol in dairy cows can reduce the deposition of liver fat, improve the reproductive performance of dairy cows, and effectively prevent dairy cow disease. The added amount exceeding the reasonable range will occur chronic poisoning of propylene glycol. In December 2016, Heilongjiang Bayi Reclamation University Animal Hospital received two sick cows diagnosed with chronic poisoming Propanediol, according to clinical symptoms combined with blood, blood glucose, free fatty acids, β-hydroxybutyric acid, and a series of test results. In this paper, the clinical symptoms, blood indexes, biochemical indexes and side effects of propylene glycol on chronic cough were analyzed.
