摘要:

2021年1月26日，贵州省六盘水市辖区内某养殖户饲养生猪出现非正常死亡。为查明原因，通过现场访谈和采样检测相结合的方法进行了现场流行病学调查。调查表明，饲喂过多霉变玉米引起的玉米赤霉烯酮蓄积性中毒可能是导致本次生猪死亡的主要原因。为防止此类中毒事件再次发生，建议养殖户在储存饲料时增设防潮板，定期观察饲料状态，禁止饲喂霉变饲料。

Abstract:

On January 26，2021，the pigs kept by a farmer in Liupanshui City，Guizhou Province abnormally died. In order to identify the causes，a field epidemiological investigation was carried out by means of site visit and sampling for detection. It was investigated that the death might be due to zearalenone accumulative poisoning caused by feeding with an excess of moldy corns. To avoid any re-occurrence of such accident，farmers were therefore recommended to add moisture-proof plates when storing feed，regularly observe the status of their feed，and prohibit feeding with any moldy feed.
