When it happened suddenly in a farm, most clinical veterinarians who are never met this case before, usually take it as other disease and make a misdiagnosis. As a result, it will delay the treatment time and lead more losses. In this paper, we reported a case of laying--duck poisoning with botulinum toxin which happened in Hunnan province recently. Based on a survey of the incidence, clinical symptom, pathological lesion and laboratory tests, it was diagnosied as poisoning caused by botulinum toxin. The aim of the present report was to improve industry awareness to the disease, so as to timely diagnosis, timely control and reduce the losses.
