Duck virus hepatitis plagued ducks for a long time, ducks can carry drugs but not disease, and less than 30 days of age ducklings resistance to the disease is weak, often showing a high lethality. Therefore, on the basis of accurately grasping the etiology, epidemiology, clinical symptoms and general rules of the disease, the author discusses the scientific prevention and control measures of the disease, and proposes a more complete, effective and more operable Comprehensive prevention and control methods, combined with practical experience to be demonstrated.
