Problems solved by technology

At present, the method of preventing and treating bird flu is to kill all the poultry within 3 kilometers of the infected poultry area, then incinerate and bury them, and inject influenza vaccines to all farmed poultry within 5 kilometers, and disperse the infected poultry. The area is quarantined for 15-30 days. Such a huge project requires a lot of people, money, and materials
Moreover, large-scale prevention has also brought a lot of losses and inconvenience to the local society, life and work.
The culling and burning of poultry will also pollute the local environment and bring difficulties to future governance
Injecting bird flu vaccines to poultry can prevent the spread of bird flu to a certain extent, but whether the meat and eggs produced by the vaccinated poultry will cause potential harm to the human body is not known yet. draw solid conclusions

Abstract

The present invention discloses one kind of feed additive for preventing bird flu and its preparation process. The feed additive consists of colocynth extract containing colocynth total alkaloid in 70-90 % and Chinese soapberry extract containing Chinese soapberry total alkaloid in 60-80 % in the weight ratio of 0.7-1 to 0.5-1. The colocynth extract and the Chinese soapberry extract are extracted from the above-ground parts of colocynth and Chinese soapberry separately. The additive is added into feed for raising fowls to prevent bird flu virus and has no latent side effect on human body caused by eating fowl products.
