The gilts have only been beaten once and then bred, is it a big problem?

Must be played 2 times, this statement is just an insurance statement without scientific basis, playing twice is just an insurance practice, if there is a condition to detect antibodies, you can determine whether you need to take two shots, if you do it once, there is no need to hit twice, it can only be said that small is very important for sows, the first batch of 180 gilts in my farm is also 1 time, because the introduction of the reserve age is a bit too large, so the time and number of seedlings have been adjusted.

Gilts are mated after only one parvovirus vaccination and may have some problems.

First of all, according to immunological principles, sows need at least two vaccinations to ensure that they produce enough antibodies to protect themselves from parvovirus infection. Therefore, if gilts have only received one vaccination, antibody levels may not be high enough to be at risk of parvovirus infection.

Secondly, if gilts are infected with parvovirus before breeding, it may lead to fetal death or poor growth due to insufficient antibody protection, and may even cause production disorders in sows.

Therefore, it is advisable to ensure that gilts are adequately vaccinated before breeding to prevent parvovirus infection. If possible, the sow's antibody levels can be tested to ensure that they have adequate immunity. If antibody levels are insufficient, a catch-up dose may be given.

If there is a stillbirth, it can be made up after childbirth (provided that swine fever and pseudorabies have been immunized to determine that it is small) swine fever, pseudorabies has been done? If you don't do it, you should make up for the pseudorabies vaccine one month before giving birth (some imported ones can be done one month before giving birth, which is safe).

Can conceive is able to conceive But drugs have an effect on these As long as the days are right, it's no problem Do pigs really get parvo? If there is a small one, it should be injected for a month before breeding, and it is not necessary to have a next time.

No.

Parvovirus infection in sows at different times has different effects on the fetus. If a sow is infected with parvovirus before mating, the fetal mortality rate is extremely high, essentially litter death. If the sow is infected with parvovirus during gestation, there is still a chance that the fetus will survive, but these fetuses will definitely be carriers of parvovirus and will become a new source of infection.

Parvovirus is highly contagious, and feed and water sources are all transmission channels.

When gilts are first mated, it is best to complete two vaccinations 20 days before breeding, and the two vaccinations should be 20 days apart, because the time for pigs to produce antibodies after vaccination is generally 15 days, and it is more appropriate to do it in advance. Gilts are immunized three times in a row, and they can basically no longer do it in the future. If the conditions are limited, you can also have two children in a row.

No.

Sow parvovirus immunization is mainly to prevent miscarriage and stillbirth, because parvovirus produces immune antibodies in about 15 days, so the general sow is immunized with parvovirus vaccine about 15-30 days before breeding, which can effectively prevent parvovirus disease in sows. Then there is the mating during the immunization vaccine, which may also affect the pregnancy rate and fertility rate.

No, the mortality rate of the fetus will be very high when the sow has parvo. Pay attention to reliable and suitable vaccines for your own pig farm, vaccine quality problems, etc.

It is best not to breed, and it is best to wait about a week to half a month. When breeding, pay attention to the size of the boar, and do not make it too big. And the boar should not be mated after eating, which will affect the quality of mating.

You can continue to breed, pay attention to let them eat better, reduce the room temperature, because pigs are afraid of heat, so that they can breed smoothly.

It should be fine! Pregnant sows are fine if they hit. View the original post

Summary. Hello dear <>

The main problems caused by over-dosed vaccines are allergic reactions and immune tolerance in sows. In the case of small inactivated seedlings, there is no problem with an excess of 1-2ml. At higher doses, there is a risk of immune tolerance that causes the sow not to produce the corresponding antibodies.

What to do if the breeding sow is small and excessive.

The main problems caused by over-dosed vaccines are allergic reactions and immune tolerance in sows. In the case of small inactivated seedlings, there is no problem with an excess of 1-2ml. Loud loud louder doses of reed keys may have immune tolerance, resulting in the sow not producing the corresponding antibodies.

Porcine parvovirus vaccine is a vaccine made by inactivating the pathogen by the method of eliminating the body, but still maintaining its immunogenicity. And a sow is normally vaccinated with parvovirus is milliliters, and 4 milliliters is obviously too much, pay attention to the sow's eating situation, fever, if there is an abnormality now, seek medical attention immediately.
