Abstract

The invention discloses a pharmaceutical composition for treating duck virus hepatitis and a preparation method thereof. The pharmaceutical composition is prepared from folium isatidis, fructus toosendan, herb of malay blumea, roots of rhodomyrtus tomentosa, brine alkali, fructus forsythia, herb of rupestrine dragonhead, diaphragma juglandis, Indian rorippa herb, radix panacis quinquefolii, licorice roots, plumula nelumbinis, amur barberry roots, bigleaf beautyberry roots, coriolus versicolor, pine leaves, all-grass of poisonous buttercrp herb, herbal swertiae mileensis, flos chrysanthemi, herbal taraxaci, herb of bentham dichrocephala, radix trichosanthis, folium apocyni veneti, semen cassiae, homlockleaved moonwort and herb of spanishneedles. The pharmaceutical composition has the advantages that antibacterial and anti-inflammation effects are achieved, the prevention and treatment effect on ducklings suffering from duck virus hepatitis is remarkable, yin and yang can be balanced, the cure rate is high, the treatment course is short, the quantity of medicine residues is small, and meanwhile the immunity and disease resistance of the ducklings can be enhanced.

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...

Problems solved by technology

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 of nutrient substance, if no attention is paid to aseptic operation or improper storage during production, it is easy to contaminate pathogenic microorganisms. cause the spread of disease

Hyperimmune serum and monoclonal antibodies are rarely used due to their high price and shortage of supply

[0005] In addition, there are few Chinese veterinary medicines on the market that can treat duck viral hepatitis. Even if some species can prevent and treat duck hepatitis, there are disadvantages that are easy to relapse and cannot be cured.
