How do sows get vaccine before and after pregnancy? When do some vaccines be appropriate? Recently, many pig friends are not very clear about these. Today, I will give you a little knowledge in this area!
It is best to complete the immunity within 1 to 3 months before the estrus breaking. Do not immune to the estrus period, because the vaccine response may affect the estrus, such as delaying the estrus period.

02. Regarding the vaccine made by sows, it is generally necessary to immune to small virus vaccines according to local conditions.
03. Active vaccine every 4-6 months.
04. Plastic sow: Before breeding, swine fever, weak poison vaccine, high pathogenic pork blue ear diseased vaccine; pig fine virus live vaccine; pig pseudo -rabies gene lacks weak poison vaccines.
05. Sowing sow: Before breeding swine fever weak toxic vaccine; highly pathogenic pork blue ear diseased vaccine; 4-6 weeks before giving birth; lack of weak toxic vaccine for pseudo-dog rabies;Two couplet seedlings.
Note: Acestated or threatened areas of encephalitis B, from March to May each year (January to February of mosquito), use type B vaccine for one month to immune twice a month; swine fever, weak toxic vaccine is recommended to use spleen vitality vaccine,Immunity can be selected according to local epidemic conditions.
3. Pregnant sow immune program flow
