Chinese medicinal composition for treating infectious bronchitis and its preparation method

Abstract

The invention discloses a Chinese medicinal composition for treating infectious bronchitis and its preparation method. The Chinese medicinal composition is prepared from vietnamese sophora roots, Rhizoma Belamcandae, Rhizoma Anemarrhenae, gypsum, Herbal Ephedrae, almonds and Radix glycyrrhizae in certain proportion. With simple formula, low cost and stable quality, the Chinese medicinal composition can be used to effectively treat infectious bronchitis. Compared with the control group of Maxingshigan decoction, the prescription of the composition has mortality decreased by 6.9%-24%, a cure rate enhanced by 6%-26.7%, and an effective rate increased by 6.9%-24%; and compared with an infected control group, the mortality is reduced by 18.2%-35.3%. Through comprehensive judgment on the characteristic lesion scores of tracheas and kidneys, the composition has good improving effects on pathological damages in chickens infected with IBV (infectiousbronchitis virus), and it not only has definite curative effects, but also has no toxic or side effect and drug residue. While improving breeding benefits, the composition also avoids causing harm to bodies of chicken eaters. Prepared by the steps of raw material grinding, extraction, and extraction solution concentration, the Chinese medicinal composition of the invention not only has stable product quality, but also has the advantages of simple process, easily controllable conditions, no discharge of ''three wastes'' during production, and environment friendliness, thus being very suitable for industrial production.

Description

Technical field [0001] The invention involves a Chinese medicine composition, which specializes in a Chinese medicine composition and preparation method that treats chicken infectious bronchitis. Background technique [0002] Infectious bronchitis (IB) is an acute, high contact infectious disease caused by the infectious bronchitis virus (IBV). Once the disease is infected, it is difficult Etexture is one of the severe infectious diseases that seriously endanger the development of the chicken industry in my country.At present, IB mainly relies on vaccination to prevent it, while strengthening breeding management to avoid the occurrence of the disease.Due to the numerous serum types of IBV, the cross -immune level between the strains is low, and the large -scale and high -intensity use of vaccines can be effectively prevented. The continuous use of vaccines, especially weak poisonous seedlings, can easily cause IBV mutations, resulting in super strong poisonous poisonThe formation...

AI Technical Summary

Problems solved by technology

Due to the large number of IBV serotypes and the low level of cross-immunity among the strains, it is necessary to use a large-scale and high-intensity vaccine to effectively prevent it. The continuous use of vaccines, especially attenuated vaccines, can easily cause IBV to mutate and lead to super-virulent Strain formation, induced IB

There is no specific drug treatment for chickens infected with IB. Nowadays, Western medicine is often used for symptomatic treatment, but the effect is often unsatisfactory, resulting in serious drug residues. Therefore, it is of great clinical significance to find new drugs to treat IB.
