Abstract

The invention relates to a feed additive for preventing avian influenza; the feed additive is composed of the following raw materials in parts by weight: 30-60 parts of folium isatidis, 20-40 parts of common St.John's wort herb, 10-30 parts of radix astragali, and 10-25 parts of liquorice. The invention also discloses a preparation method of the feed additive. The feed additive not only can prevent and control avian influenza but also can improve the immunity of animals, and has the characteristics of small side effects, low cost, simple process and easy industrialization.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a feed additive for preventing and treating bird flu and a preparation method thereof. Background technique [0002] Avian influenza (Avian Influenza, AI) is an infection of poultry caused by influenza A virus of the Orthomyxoviridae family. Because the avian influenza virus has many gene segments and is easy to mutate and recombine, it is difficult for chemical drugs and vaccines to exert their best control effects. Under the trend of thinking of returning to nature today, the issue of food safety has attracted more and more attention from the world, and the green prevention and control of poultry diseases has become the mainstream. [0003] my country is rich in resources of Chinese herbal medicines. Chinese herbal medicines have comprehensive effects such as inhibiting virus replication, regulating immune function, preventing virus-induced cytopathy, analgesia and anti...
