The sow has been bred, can you still shoot small seedlings?

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.

1, sows can be injected with parvo vaccine 10 days after giving birth, if the sow produces more than three times, there is no need to inject parvo vaccine, which and 2, after breeding, sows can be injected with swine fever, pseudorabies vaccine, different vaccines are done at intervals of one week, **Program dry cong: sow immunization reference, 45 days before giving birth to inject gastric flow double vaccine (winter and spring), 30 days before birth injection of pseudorabies vaccine (each litter is done), 20 days before birth injection of E. coli vaccine K88 or K99 (selective preventive immunization), 14 days postpartum injection parvo + JE (one side of the injection with Li defeat, after the birth of the third child can be injected with a single injection of JE vaccine), 21 days after the birth of the swine fever vaccine (each fetus is done), 28 days after the birth of the foot-and-mouth disease vaccine (autumn, winter and spring).

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, 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

15-30 days.

Porcine parvovirus infection (PPI), also known as porcine reproductive disorder, is a class II infectious disease and parasitic disease. It is a reproductive disorder of pigs caused by porcine parvovirus. It is characterized by abortions, stillbirths, and mummies in pregnant sows.

Porcine parvovirus disease is a swine reproductive disorder caused by porcine parvovirus (PPV), which is mainly manifested by the infection and death of embryos and fetuses, especially stillbirths, malformed fetuses and mummified fetuses in primiparous sows, but the sows themselves have no obvious symptoms.

Parvovirus (PPV) is very resistant to the external environment, in order to maintain an infection-free farm, strict hygiene measures must be taken, try to adhere to self-breeding, such as the need to introduce breeding pigs, must be introduced from the parvovirus (PPV) infection-free pig farm. When the HI titer is below 1:256 or negative, it is allowed to be introduced.

After the introduction, it is strictly isolated for more than 2 weeks, and when the HI test is negative again, it can be mixed and reared in groups. Sick farms, should be especially to prevent gilts from being infected during the first litter feeding, can delay their mating period to 9 months of age, when the maternal antibody has disappeared ((maternal antibody can last an average of 21 weeks), through artificial active immunization to make it immune and then breeding.

Parvovirus vaccination in sows can optionally be given a few weeks before mating (usually 2 weeks before). In order to ensure that pregnant sows maintain strong immunity during the susceptible period.

Sow parvovirus vaccines include live vaccines and inactivated vaccines. Live vaccines produce high antibody titers and have a longer maintenance time, while inactivated vaccines have a shorter immunization period, generally only half a year. To prevent interference from maternal antibodies, the time of immunization can be determined by two injections or by measuring the HI titer with an antibody titer greater than 1:

At 20, it is not suitable for injection, and when the antibody titer is higher than 1:80, it can resist PPV infection. In order to provide strong immunity for sows in production, it is best to immunize pigs before each breeding, which can be injected twice with inactivated oil emulsion seedlings to avoid the interference of passive immunity already existing in the body.

The prevention and control of animal diseases should adhere to the policy of "prevention first, supplemented by first, and combined with prevention and control". At present, the use of vaccines is an effective way to prevent porcine parvovirus disease and improve disease resistance and reproduction rate in sows.
