In June 2017,death cases with unknown reasons appeared in a deer farm in Chengde City of Hebei Province.Through field epidemiological survey and laboratory diagnosis,Clostridium welchii was confirmed as the main reason leading to the death,and a sudden proportion increase of soybean meal without authorization mainly induced the disease. According to the suggestions proposed after the survey,some measures were adopted by the owner,such as gradually decreasing the proportion of soybean meal,strengthening isolation and sterilization and giving symptomatic treatment. At last,no death was found again after 15 days of treatment.%2017年6月河北省承德市某梅花鹿养殖场饲养的鹿先后出现不明原因死亡现象.经现场流行病学调查和实验室诊断,确定魏氏梭菌是导致鹿群死亡的主要原因,突然擅自增加豆粕比例是引起该病的主要诱因.场主按照调查后提出的建议,通过逐步降低豆粕比例、隔离消毒、药物对症治疗等措施,15 d后该场未再发生死亡现象.
