Problems solved by technology

[0004] Although many countries have announced that they have developed vaccines against highly pathogenic avian influenza viruses, because avian influenza viruses are RNA viruses, and like all RNA viruses, avian influenza viruses have a high degree of variability, which means Vaccines developed by human beings at a great cost may fail or have greatly reduced effects due to virus variants and subspecies before large-scale clinical application or shortly after clinical application, and cannot effectively prevent avian influenza virus

Abstract

The present invention relates to veterinary medicine for preventing and treating animal's epidemic disease. The veterinary medicine is prepared with triperygium wilfordii, hairystalk loosestrife herb, aniseed, forsythia, clove and other materials, and through alcohol solution extraction, distillation of the extract liquid, adding beta-cyclodestrin and starch through stirring and spray drying. The veterinary medicine can inhibit flu virus, prevent diseases and kill pathogenic microbes, and is added into farm animal feed to prevent and treat diseases.

Description

technical field [0001] The invention relates to veterinary medicine, in particular to a medicine for preventing and treating livestock and poultry epidemic diseases, as well as a preparation method and application of the medicine. The invention is particularly suitable for avian influenza. Background technique [0002] Epidemic diseases of livestock and poultry, such as bronchitis, laryngotracheitis, and influenza, are common and frequently-occurring diseases of livestock and poultry. Most of them are caused by climate change or poor feeding management, which lead to the decline of livestock and poultry physique and the invasion of cold viruses. Such diseases can usually cause large-scale epidemics through airborne or contact infection. Due to the large number of breeding and the concentration of livestock and poultry in general farms, once such a disease occurs, it can affect the entire livestock and poultry group within a few days. If it cannot be controlled and treated i...
