Preparation method of radix isatidis Erhuang powder for treating infectious bursal disease of chickens

Abstract

The invention discloses a preparation method of radix isatidis Erhuang powder for treating an infectious bursal disease of chickens. The powder is prepared from the traditional Chinese medicine raw materials in parts by weight: 25-40 parts of radix isatidis, 25-35 parts of fructus forsythiae, 40-50 parts of bighead atractylodes rhizomes, 50-70 parts of radix astragali, 30-40 parts of cortex phellodendri, 25-40 parts of haws, 30-40 parts of digitalis, and 35-45 parts of herba epimedii. The preparation method comprises the steps of (1) crushing radix astragali, cortex phellodendri, haws, digitalis and herba epimedii, and adding compound enzymes for enzymolysis; (2) performing extraction twice; (3) performing concentration so as to obtain a medicinal extract; (4) separately crushing radix isatidis, fructus forsythiae, and bighead atractylodes rhizomes so as to obtain radix isatidis powder, fructus forsythiae powder and bighead atractylodes rhizome powder; (5) mixing the radix isatidis powder with the medicinal extract, performing pelletization, performing granule tidying, performing drying, adding the fructus forsythiae powder and the bighead atractylodes rhizome powder, performing uniform mixing and performing screening; and (6) performing packaging. According to the preparation method of the radix isatidis Erhuang powder for treating the infectious bursal disease of chickens, disclosed by the invention, the radix isatidis Erhuang powder has a notable treatment effect on the infectious bursal disease, and the dissolution rate of effective components of medicinal materials is increased.

Description

technical field [0001] The invention relates to the technical field of veterinary medicine, in particular to a preparation method of Banerhuang powder for treating chicken infectious bursal disease. Background technique [0002] Infectious bursal disease of chickens is an acute and highly contagious disease that harms chicks. Chicken infectious bursal virus mainly infects the central immune organ of chickens—the bursa, which leads to immunosuppression or insufficiency of the body, making chickens very susceptible to other infectious diseases, and bringing serious economic losses to the chicken industry. loss. At present, the treatment of this disease mainly uses egg yolk antibody of chicken infectious bursal disease, and most of the production of egg yolk antibody does not use eggs produced by SPF (specific pathogenic microorganism-free) chickens, thus causing pathogenic microorganisms to pass through the egg yolk antibody. Pass it to chickens, even if the eggs produced by...

Problems solved by technology

At present, traditional traditional Chinese medicine veterinary drug extraction methods, such as hot water, acid, alkali, and organic solvent extraction methods, are hindered by the main component of cell walls, cellulose, and the extraction efficiency is often low, and the yield of active ingredients is low, and a large number of active ingredients in plants The cell wall is not released into the extraction solvent, and more active ingredients are lost, which greatly reduces the economic benefit of the preparation
