Problems solved by technology

The effective measure to prevent the occurrence of bird flu is to vaccinate. When the vaccinated vaccine is consistent with the subtype of clinically circulating strains, the ideal protective effect can be obtained, but when the vaccinated vaccine is different from the circulating subtype, immune protection cannot be obtained.
There are many serotypes of avian influenza virus, and genetic recombination will occur when different subtypes of influenza A virus are mixed-infected to form a new avian influenza virus, which brings great difficulties to the development and application of vaccines
In production practice, immunization failure often occurs due to incompatibility between the inoculated vaccine and the circulating strain subtype
Therefore, it is difficult to completely control the occurrence and prevalence of bird flu only by bird flu vaccine.

Abstract

The invention relates to a feed with medicinal functions, and concretely relates to a Chinese herbal medicinal premixed feed for preventing avian influenza of chickens, and a preparation method thereof. The Chinese herbal medicinal premixed feed comprises, by weight, 2-4 parts of honeysuckle flower, 2-3 parts of Herba Schizonepetae, 2-3 parts of Caulis Perillae, 2-3 parts of Radixet Rhizonma Ephedrae, 2-3 parts of Divaricate Saposhnikovia Root, 2-3 parts of white peony root, 2-4 parts of Radix Platycodonis, 2-4 parts of dry ginger, 2-3 parts of Cyrtomium fortunei, 6-7 parts of isatis root, 6-7 parts of Folium Isatidis and 60-65 parts of rice bran. A result of chicken serum examination of chicken flocks fed with the Chinese herbal medicinal premixed feed in a Hunan Polytechnic of Environment and Biology lab shows that the H1 antibody average level is higher than 410 g<2>.

Description

technical field [0001] The invention relates to a feed with medicinal function, in particular to a Chinese herbal medicine premixed feed for preventing bird flu in chickens and a preparation method thereof. Background technique [0002] Human infection with avian influenza is a human disease caused by an avian influenza virus. Avian influenza virus, which belongs to type A influenza virus, is divided into three levels of high, medium and low / non-pathogenicity according to the pathogenicity of avian influenza virus to chickens and turkeys. Due to the characteristics of the hemagglutinin structure of the avian influenza virus, it generally infects poultry. When the virus undergoes gene reassortment during the replication process, resulting in a structural change and the ability to infect humans, it may cause human infection with avian influenza. The subtypes of avian influenza virus that can directly infect humans have been found so far: H5N1, H7N1, H7N2, H7N3, H7N7, H9N2 and...
