Problems solved by technology

[0004] At present, the control of infectious diseases in large-scale pig farms mainly relies on the triangle system of vaccine prevention, biosafety, and western medicine control (Shao Guoqing, Drugs and vaccines for the prevention and control of swine asthma, China Animal Health, 2003, 54(8): 21-23), but mycoplasma It can change the surface antigen to cause immune escape, resulting in weak immunity. In addition, the immunization route of thoracic injection is not easy to be accepted by ordinary users, so its promotion and application are limited. Therefore, western medicine is still the main treatment for high infection rate breeding pig farms. Mainly, the most commonly used western medicines to treat this disease are antibiotics. Although the therapeutic effect is obvious, the application of antibiotics is easy to produce drug resistance, the drug residue time is long, the cost is high, and it seriously affects the growth rate of pigs, resulting in economic losses for farmers.

Abstract

The invention discloses a Chinese medicinal composition for preventing and treating swine enzootic pneumonia, which comprises the following components in part by weight: 25 to 40 parts of tatarian aster root, 15 to 28 parts of sessile stemona root, 10 to 20 parts of bitter apricot seed, 8 to 15 parts of white mulberry root-bark, 10 to 20 parts of loquat leaf and 8 to 20 parts of houttuynia cordata. The Chinese medicinal composition disclosed by the invention has high cure rate on swine enzootic pneumonia; by observing a curative effect of an artificially pathogenetic swine enzootic pneumonia model, high and middle dose groups of tested medicaments have obvious effects on the curative effect on swine enzootic pneumonia and weight increase of swines; and the Chinese medicinal composition is totally suitable for preventing and treating swine enzootic pneumonia.

Description

technical field [0001] The invention relates to a traditional Chinese medicine composition, in particular to a traditional Chinese medicine composition for preventing and treating swine asthma and its preparation and application. Background technique [0002] Pig asthma (mycoplasma swine pneumonia, porcine endemic pneumonia) is a direct contact, chronic respiratory infectious disease. The pathogen of this disease is Mycoplasma hyopneumoniae (Mhp), and the main clinical manifestations are cough and wheezing. The pathological changes are mainly located in the thoracic cavity, and the lung is the main organ of the lesion. The acute cases are mainly pulmonary edema and emphysema; , 3rd edition, China Agricultural Press, 1996, Beijing, 141-144). Pig asthma is widely prevalent in the world, with a high incidence rate and difficult eradication, resulting in slow growth of affected pigs, low feed utilization rate, and prolonged fattening and rearing period. Especially in the mode...
