Abstract

The invention belongs to the technical field of veterinary drugs and particularly relates to a drug for treating the porcine reproductive and respiratory syndrome and a preparation method of the drug.The drug is prepared from the raw materials in parts by weight as follows: 10-20 parts of fructus forsythiae, 5-10 parts of herba houttuyniae, 1-5 parts of radix bupleuri, 2-4 parts of folium isatidis, 3-6 parts of caulis lonicerae, 10-20 parts of radix scrophulariae, 1-5 parts of cortex moutan, 1-3 parts of poplar flowers, 10-20 parts of ramulus cinnamomi and 1-5 parts of garlic. The drug for treating the porcine reproductive and respiratory syndrome can effectively increase nutrition required for growth of pigs, improve resistance of the pigs, promote growth and reduce morbidity and is simple to prepare.

Description

Technical field [0001] The invention belongs to the technical field of veterinary medicine, and in particular relates to a medicine for treating porcine blue ear disease and a preparation method thereof. Background technique [0002] In recent years, in many areas of the country, an infectious disease has been prevalent in pigs during the summer and autumn seasons. The pathological changes are mainly in the respiratory system and lymphatic tissues. Almost all lymph nodes have bleeding, especially the hilar lymph nodes, groin lymph nodes and mesenteric lymph nodes. . Diffuse interstitial inflammation. There are bleeding spots and spots in the lungs. Most of the dead pigs have mild gastric ulcer, fibrinous pleurisy, and peritonitis, and some have pericarditis. Some of the hearts are swollen and yellowish, the texture becomes brittle, the bladder has bleeding spots, the spleen is enlarged, and hemorrhagic infarction. In actual production, sick and dead pigs are often double or mul...
