湖北省规模化养鸭主要疫病流行情况调查

摘要

对2006～2009年湖北省规模化养鸭主要疫病的流行情况进行实地调查和实验室诊断.共调查7个地(市)79个养鸭户和养鸭场182 850只鸭的主要疾病流行情况.成年鸭主要疾病有禽流感、鸭瘟、副粘病毒病、巴氏杆菌病、大肠杆菌和沙门氏菌混合感染等,调查36群成年鸭共83 200只,其中发病26 890只,发病率32.3％；死亡6 737只,病死率25.1％；对产蛋鸭生产性能均有不同程度影响.雏鸭的主要疾病有鸭病毒性肝炎、鸭疫里默氏杆菌病、大肠杆菌病和沙门氏菌病等,调查43群雏鸭共99 650只,其中发病19 720只,发病率19.8％；死亡5 541只,病死率28.1％.从采集的病料中分别分离到7株禽流感病毒、3株副粘病毒和3株鸭肝炎病毒；分离到17株鸭疫里默氏杆菌、36株大肠杆菌、9株巴氏杆菌等病原菌.%The epidemic situation of main diseases in scale duck-breeding farms from 2006 to 2009 was analyzed by on-site investigation and laboratory diagnosis. 182 850 ducklings and ducks from 79 duck farms in 7 districts of Hubei province were investigated and detected. The results showed that the ducks were mainly mix-infected with avian influenza virus, Duck plague virus,avian Paramyxoviridae virus, avian Pasteurella multocida, Escherichia coli and avian salmonellosis. In the investigated 83 200 ducks from 36 flocks, 26 890 ducks were infected, and 6 737 ducks died, the morbility and mortility was 32.3% and 25.1%, respectively. The ducklings were mainly infected by Duck viral hepatitis, Riemerella anatipestifer, E. Coli and avian salmonellosis. In the investigated 99 650 ducklings from 43 flocks, 19720 ducklings were infected and 5 541 ducklings died, the morbility and mortility was 19.8% and 28.1%, respectively. From these samples, 7 AIV strains, 3 Paramyxoviridae virus strains and 3 DHV strains, 17 R. Anatipestifer strains, 36 E. Coli strains and 9 avian P. Multocida strains were isolated.
