Description

technical field [0001] The invention relates to the field of veterinary medicine, in particular to a pharmaceutical composition for treating duck viral hepatitis and a preparation method thereof. Background technique [0002] Duck viral hepatitis is mainly an acute infectious disease caused by duck hepatitis virus. It has a short course of disease, high incidence, rapid spread and high mortality. Duck hepatitis virus (DHV) has three serotypes: I, II, and III. Types I and III are enteroviruses of the picornaviridae family, and type II is an astrovirus. There is no cross-immunity between the serotypes. , Most of the pathogens popular in my country are type I duck hepatitis virus. The disease occurs throughout the year, but it often occurs in spring or winter. It mainly affects ducklings within 3 weeks of age through digestive tract and respiratory tract infections. The mortality rate of ducklings within one week of age is as high as 95%, the mortality rate of ducklings at the...

High-immunity yolk antibodies have the disadvantage of being difficult to preserve. Sometimes repeated injections of high-immunity yolk antibodies are difficult to control the disease. Moreover, most of the production of yolk antibodies does not use duck eggs produced by ducks without specific pathogenic microorganisms, resulting in Pathogenic microorganisms are transmitted to ducks through egg yolk antibodies. Even if duck eggs produced by ducks without specific pathogenic microorganisms are used, since egg yolk itself is a kind
