Description

technical field [0001] The invention relates to a feed additive and a preparation method thereof, in particular to a feed additive for preventing bird flu and a preparation method thereof. Background technique [0002] Avian influenza is an infectious virus that may break out at any time with the change of seasons and the migration of migratory birds. It is characterized by no warning, rapid spread, and will cause plague in a short time. Scientific research has confirmed that in the outbreak of bird flu, two types of viruses (H5N5 strain and H7N7 strain) are known to be harmful to human health and cause the death of humans infected with bird flu.

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
