Chinese medicinal composition for preventing and treating swine enzootic pneumonia as well as preparation and application thereof

Abstract

The invention discloses a traditional Chinese medicine composition for preventing and treating swine asthma, which comprises the following components in parts by weight: 25-40 parts of aster, 15-28 parts of peccary, 10-20 parts of bitter almond, and 8-15 parts of cortex mulberry , 10-20 parts of loquat leaves, 8-20 parts of Houttuynia cordata. The traditional Chinese medicine composition of the present invention has a very high cure rate to swine asthma. Through the observation of the curative effect on the swine asthma model of artificial disease, the high and medium dose groups of the tested drug have the effect on the curative effect of swine asthma and the weight gain of pigs. Obviously, it is completely suitable for the prevention and treatment of swine asthma.

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...

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.
