Abstract

The invention discloses a mixture for preventing and treating infectious pleuropneumonia of pigs and a preparation method of the mixture. The preparation method includes the steps that dark plum extract, coptis chinensis extract, and polygonum cuspidatum extract are mixed according to a certain proportion, subjected to ethanol precipitation and filtration concentration and then mixed with solubilizer and preservative to be stirred and fully dissolved, and the mixture is obtained. The mixture has the advantages of being good in preparation stability, high in process repeatability, simple in process, high in operability, reasonable in cost and the like. The prepared mixture is sepia, transparent and homogeneous liquid and can be taken orally or stirred conveniently, the production practice and veterinarian clinical test show that the mixture can prevent and treat the infectious pleuropneumonia of the pigs, lower the bacteria number of the pathogenic bacteria of sick pigs, eliminate lung inflammation lesion of the pigs, lower the death rate of the pigs and achieve production increase.

Description

technical field [0001] The invention relates to a Wuhuanghu mixture for preventing and treating porcine infectious pleuropneumonia and a preparation method thereof, in particular to a Wuhuanghu mixture capable of preventing and treating porcine infectious pleuropneumonia and a preparation method thereof. Background technique [0002] Porcine contagious pleuropneumonia ( Porcine infectious pleuropneumonia ) is a highly contagious respiratory disease of pigs caused by Actinobacillus pleuropneumoniae, also known as porcine contagious pleuropneumonia. Characterized by acute hemorrhagic fibrinous pleuropneumonia and chronic fibrinous necrotizing pleuropneumonia, the acute form presents a high mortality rate. Porcine infectious pleuropneumonia is a worldwide disease that is widely distributed in all pig-raising countries in the world, such as the United Kingdom, Germany, Switzerland, Denmark, Australia, Canada, Mexico, Argentina, Sweden, Poland, Japan, the United States, and Chin...
