为了解樱桃谷种鸭不同生长饲养阶段主要传染病的流行情况,对中国南方地区饲养的不同日龄的樱桃谷种鸭开展了重要病原的感染调查。结果显示,4周龄内的育雏期樱桃谷种鸭主要发生鸭传染性浆膜炎、鸭Ⅰ型病毒性肝炎和鸭大肠杆菌病,5～21周龄的育成期樱桃谷种鸭主要为鸭大肠杆菌、鸭疫里默氏杆菌、鸭圆环病毒感染,鸭霍乱和新城疫也时有发生,产蛋期樱桃谷种鸭主要发生鸭大肠杆菌病,同时还有坦布苏病毒病和鸭圆环病毒感染。可见,近年来中国南方樱桃谷鸭群疫病发生日趋复杂,形势严峻,且不同生长阶段的疫病发生情况不尽相同,为樱桃谷种鸭主要流行疫病的防控提供科学依据。

To investigate the prevalence of major epidemics in cherry valley ducks in southern China,the author detected infectious agents in samples of cherry valley duck in different growth period collected from southern China.The results showed that:the major infectious diseases occurred among brooding cherry valley ducks(1-4-week-old) were mainly duck infectious serositis,duck viral hepatitis type Ⅰ and duck E.coli.Cherry valley ducks during growing-finishing period(5-21-week-old) were mainly infected with duck E.coli,R.anatipestifer and duck circovirus,from which avian Pasteurella multocida and Newcastle disease virus were also isolated occasionally.Cherry valley ducks during laying period were mostly infected with duck E.coli,and also could be infected with duck tembusu virus or duck circovirus.The results indicated that the situation of epidemics in cherry valley duck was becoming increasingly complex and grim,and the infectious agents in different growth stages were not the same.The surveillance of epidemics would be helpful for the prevention and control of diseases in cherry valley duck.
