Why are sows vaccinated against parvovirus on day 14?

The main reason sows are vaccinated against parvovirus on day 14 is to prevent and control parvovirus disease. Because sows are highly susceptible to this virus in the early stage, and once they contract parvovirus disease, almost 100% of the piglets born are stillborn; even if they are not stillborn, the piglets may be malformed, become mummified fetuses, or the sow may have difficulty conceiving. Therefore, for the safety of both the sow and the piglets, it is best to vaccinate against parvovirus on day 14.

How do you prevent and control porcine parvovirus disease?

1. Persist with self-breeding and self-raising to prevent the introduction of pathogens into the pig farm. When breeding pigs must be introduced, two hemagglutination inhibition tests need to be done; when the hemagglutination inhibition titer is 1:256, they can be introduced.

2. Do a good job of isolated rearing, carry out harmless treatment of sick and dead pigs, and strictly disinfect the pig farm site and equipment.

3. Prevention of this disease mainly relies on strengthening immunity, by inoculating inactivated porcine parvovirus vaccine and attenuated vaccine. Replacement gilts and boars are given a 2ml intramuscular injection of the vaccine 1~2 months before mating for the first immunization, followed by a second immunization 2 weeks later.

4. For sows that contract the disease during pregnancy, inject cephalosporin injection twice daily for 3~5 consecutive days.

5. For diseased pigs with delayed farrowing, promptly inject prostaglandin injection to induce labor, to prevent fetal putrefaction from being retained in the uterus and causing infertility or endometritis.

The above is an introduction to why sows are vaccinated against parvovirus on day 14. We hope it is helpful to everyone.
