Problems solved by technology

High-immune yolk antibodies have the disadvantage of being difficult to preserve. Sometimes repeated injections of high-immune yolk antibodies are difficult to control the disease. Moreover, most of the production of yolk antibodies does not use duck eggs produced by SPF (specific pathogenic microorganism-free) ducks. , thus causing pathogenic microorganisms to be transmitted to ducks through yolk antibodies. Even if duck eggs produced by SPF ducks are used, because yolk itself is a kind of nutrient substance,

Example Embodiment

[0084] The present invention also provides the preparation method of the above-mentioned traditional Chinese medicine composition for preventing and treating duck viral hepatitis, which comprises:

[0085] In the first step, each component is mixed and pulverized according to the stated ratio;

[0086] In the second step, the pulverized mixture obtained in the first step is added to ethanol for heating and reflux extraction, and the extracts are combined, centrifuged, and filtered to obtain a purified ethanol extract;

[0087] The third step is to obtain a traditional Chinese medicine extract by evaporating the ethanol in the ethanol extract in the second step;

[0088] In the fourth step, the traditional Chinese medicine extract obtained in the third step is redissolved in deionized water, and the traditional Chinese medicine extract is recovered by adsorption with a macroporous adsorption resin, and then eluted with deionized water;

[0089] The 5th step, uses the method of...
