Abstract

The invention provides a traditional Chinese medicine composition used for preventing and treating high-pathogenicity porcine reproductive and respiratory syndrome (PPRS). The composition comprises common anemarrhena, gypsum, snakegourd root, common lophatherum herb, reed rhizome, honeysuckle flower, Baikal skullcap root, red peony root, lanceolate dichotomous starwort root, ligusticum, sanna leaf, pilose asiabell root, and Mongolian milkvetch root. According to the invention, when the high-pathogenicity PPRS is treated by using the traditional Chinese medicine composition, the medicine composition is advantaged in substantial treatment effect, high curative rate, no toxic or side-effect, low reoccurrence rate, no drug induced suffering, and low cost. With the traditional Chinese medicinecomposition, both root causes and symptoms can be treated, and the meat quality satisfies a standard of commodity inspections.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese veterinary medicine, in particular to a traditional Chinese medicine composition for preventing and treating highly pathogenic pig blue-ear disease. [0002] Background technique [0003] Ecological pig production is a major industry for the development of animal husbandry in my country, and it is also a main pillar for foreign exchange earnings from the export of animal husbandry products in my country. It is to increase national income and improve people's living standards, accelerate the development of agriculture and animal husbandry, and adjust the structure of agricultural industrialization. important goal. [0004] "Highly pathogenic porcine blue-ear disease", also known as "high fever", is a polar and highly fatal disease caused by a mutant strain of porcine reproductive and respiratory syndrome virus. Since it was introduced into my country in 1995, it has Several large epidem...
