| 摘 要： | 本文通过1996年1月～1998年9月郑州地区296例鸭病毒性肝炎病例的分析,结合种鸭场、养鸭户的调查,对鸭病毒性肝炎的发病规律和发病原因进行了综合的分析研究。结果发现,郑州地区鸭病毒性肝炎发病日龄以5～15日龄最多,发病日龄在逐年增大;发病月份以5～6和9～11月最高,而且混合感染病例增加。在病因的调查中发现,除了种鸭免疫和母源抗体影响外,相当多的发病属于养殖户对传染病的认识不足而造成的。

| Abstract: | From January 1996 to September 1998,296 cases of virus hepatitis in ducks were analyzed for Zhengzhou Area in combination with an investigation of breeder duck farms. Laws and causes of occurrence of virus hepatitis in ducks were comprehensively researched into. It was discovered that virus hepatitis in ducks in Zhengzhou Area happened mostly at 5 -15 days of age and in the months of May-June and September-November,with mixed infections increasing. Etiological analysis led to the discovery that apart from breeder duck vaccination and maternal antibody, occurrence of the disease was mostly due to little knowledge of infectious diseases. |
