Three kinds of vaccines that pigs must be vaccinated.

The three vaccines that pigs must be vaccinated are as follows:

1, swine fever vaccine. Classical swine fever vaccine is the most mature and accurate vaccine for pigs. The best vaccine is cell vaccine. The swine fever vaccine is well done, and there are few problems in the pig farm. It is best to follow up the fetus twice a year, each time 1.5-2 doses.

2, viral diarrhea vaccine. At present, many pig farms have diarrhea and diarrhea, and all kinds of drugs can't stop. Give 1 dose of diarrhea and live diarrhea vaccine 45 days before delivery and 15 days before delivery, respectively, to completely put an end to the death of piglets from diarrhea, 2 doses each time.

3. Parvovirus vaccine. There are basically no symptoms after multiple births. The reserve sow is immunized once before mating, once after giving birth to a fetus, once after giving birth to a second child, once after giving birth to a second child and once after giving birth to a third child, twice each time.

Under the condition of intensive farming, it is our ideal goal to reduce or terminate some vaccines. Too much inoculation may seriously affect the growth rate of pigs. The general principles of vaccination are: the number of vaccinations of the same or different kinds should be less than more; The interval between vaccinations of the same or different kinds of vaccines should be longer than shorter.

The time for vaccination of pigs should be sooner rather than later (try to avoid the use of advanced immunization to prevent immune paralysis). Remember, in the pig industry, immunity is domesticated, and most pathogenic microorganisms can be domesticated. After understanding the epidemic law of diseases, the idea of domestication must run through the whole breeding process.
