How to Give Pigs Injections for Disease Prevention? A Detailed Guide to the Correct Method

Swine fever lapinized attenuated freeze-dried vaccine prevents swine fever.

Regardless of the pig's size, the dose is 1 ml. If there is already an outbreak near the pig farm, two immunizations are preferable, the first at 21-30 days of age, and the second after weaning (around 65 days of age). Pregnant sows can also be injected. Generally, immunity develops 4 days after injection, and the immune period lasts more than 1 year.
