Problems solved by technology

However, the phenomenon of increased atavistic virulence and safety issues of attenuated PRRS vaccines have increasingly aroused people's concerns
At home and abroad, the use of attenuated vaccines has caused many PRRS outbreaks in pig herds. Therefore, live vaccines should be used with caution; while the immune efficacy of inactivated vaccines is very limited or uncertain, which has brought great challenges to the prevention and treatment of pig PRRS. uncertainty

Abstract

The invention relates to premix feed capable of preventing and curing porcine reproductive and respiratory syndrome (PRRS) of pregnant sows. The premix feed is prepared from a nutrition additive, a Chinese herbal medicine additive and a diluent; the raw medicinal material content of the Chinese herbal medicine additive is 0.5-8% of the weight of the premix feed; the Chinese herbal medicine additive is prepared by extracting or directly grinding the following medicines in parts by weight: 0.5-3 parts of honeysuckle flower, 0.5-3 parts of herba houttuyniae, 0.5-3 parts of radix paeoniae rubra, 0.5-3 parts of radix astragali seu hedysari and 0.5-3 parts of cortex mori; the diluent is a mixture of zeolite powder and rice hull powder, wherein the weight ratio of the zeolite powder to the rice hull powder is equal to 1 to 1. The premix feed can meet vitamins, trace elements, amino acids and the like which are needed by staged growth and development of the pregnant sows, improves production efficiency and enhances immunity; the Chinese herbal medicine additive added into the premix feed has the functions of clearing away heat and toxic materials, eliminating carbuncle and removing pus, cooling blood and dispersing blood stasis, strengthening body resistance and dispelling evils, resisting bacteria and eliminating inflammation, and the like; therefore, the premix feed improves the body immunity, disease resistance and anti-stress ability of pigs, and has a remarkable effect for preventing and treating highly pathogenic PRRS.

Description

technical field [0001] The invention belongs to the application field of agriculture and animal husbandry, and in particular relates to a premixed feed for preventing and treating blue ear disease of pregnant sows and a preparation method thereof. Background technique [0002] Porcine blue ear disease (PRRS) is caused by porcine reproductive and respiratory syndrome (commonly known as PRRS) virus, which belongs to Arteriviridae and Arterivirus genus. Respiratory symptoms of pigs are the main features. In severe cases, depression and dyspnea may occur. Due to dyspnea and hypoxia, the tips and sides of the ears appear blue and purple, so it is called "blue ear disease". [0003] Pig highly pathogenic PRRS mostly occurs in the high temperature season in late spring and early summer, especially in poor breeding environment, poor ventilation and cooling in pig houses, hot and humid, free-range farmers and small pig farms with excessive stocking density, Infected pigs showed hig...
