Detail
  • Product Name: Porcine reproductive and respiratory syndrome virus vaccine
  • Product Number: 006

Reproductive and respiratory syndrome with inactivated vaccine for sows to newborn piglets through the colostrum to provide passive immunity to protect pigs from PRRSV during the invasion of breast-feeding. Tests showed that the immune sows farrow in 24-28 days to maternal antibodies could be detected.

1, the high degree of security

Vaccine attenuated strain, virulence is not back strong, safe, stable

Free for general

Safety Test:

From the two aspects of testing the vaccine strains used PRRSCH-1R security:

First: back strong toxicity test: choice of blue ear virus gestational age 85-93 most sensitive a test re-birth sows, the pigs subculture after 3 to 4 times difficult in serum, nasal swabs detected viral nucleic acid testing sow reproductive disorders, no clinical manifestations, indicating PRRSCH-1R strain is stable genetic traits.

Second: the different immunization doses of the vaccine was tested the safety of, respectively, repeated immunization with a single dose, 10 times the large dose of immunization of pregnant sows and weaned piglets immunization results observed, the batch of vaccine clinical symptoms of piglets and sows farrowing conditions were normal. Prove that the vaccine is safe and pigs.

2, Super Potency

Vaccine strains isolated in the Americas for the domestic strains. 2006 "nameless fever syndrome" in the blue ear disease isolates more than 98% homology.

Faster boot protection, an effective protection force. Immune antibodies 1 week, 2 weeks to produce a protective force, can be used for emergency immunization.

Vaccine potency than 105.0TCID50 / head copies.

Immunization period of up to 4 months.

Protective immunity test:

Detection of antibody after immunization: immunization of 28 to 35 days old piglets, 7 days after immunization, will be able to detect PRRSV in the IFA antibody 2 weeks after immunization, 80% of the pigs can be protected.

Minimum dose and dose: the vaccine titer 104.0TCID50 / first copies of the immunization dose, can completely protect against virulent piglets and sows the attack, in order to ensure the use of the vaccine effect, we will use the dose of the vaccine as 105.0 TCID50 / head were, in fact, the standard of our factory as 106.0TCID50 / head copies, equivalent to 100 times the minimum dose.

Duration of immunity: more than 3 were used by the batch of the vaccine, were immunized with 28 to 35-day-old piglets and pregnant sows 1, 5 months after immunization, attack of virulent virus, protection rate was 100%. For security reasons, we will be immune protection period to four months.

3, low immune stress

Healthy herd immunity no increase in body temperature, decreased feed intake and impact of weight gain phenomenon.

Porcine reproductive and respiratory syndrome vaccine (Ch-1a strain)

Good safety

Because reproductive and respiratory syndrome vaccine itself, the nature of the vaccine has a good safety, the seedling selection of domestic isolates (CH-1a strain), the strain is by Marc-145 cell line passaged several times Cloning and purification, screening addicted to Marc-145 cell growth of PRRSV strain, the strain of the cell culture medium inactivated by chemical reagents, together with the medical oil adjuvant, made into a reproductive and respiratory syndrome vaccine. Times the amount of the vaccine to pregnant sows and piglets intramuscular injection, with the exception of local pigs inoculated with the normal response, the vaccinated pigs without systemic reactions, the spirit, loss of appetite Dengjun not be affected, proved that the vaccine has a good safety. Because the vaccine Simiao, so easily abandoned Sandu attenuated the risk of it applies to pigs as possible.

Strong effect to the immune

The selection of domestic isolates (CH-1a strain) development, with a good immune protection, immune characteristics of a long duration of the test proved that pigs in the second immunization 20 days after the seedlings, you can generate a strong immune power, 80% of the immune pigs can withstand virulent attacks. And its immunity period of up to 6 months old, so the vaccine is a kind of guts and anti-PRRS PRRS negative field preferred vaccine.

Newborn piglets can provide a good passive immunization

Reproductive and respiratory syndrome with inactivated vaccine for sows to newborn piglets through the colostrum to provide passive immunity to protect pigs from PRRSV during the invasion of breast-feeding. Tests showed that the immune sows farrow in 24-28 days to maternal antibodies could be detected.

Vaccine's shelf

Reproductive and respiratory syndrome will be placed in the inactivated vaccine stored at 2-8 ℃ conditions, periodic sampling for determination of physical properties, and more than 4 weeks old PRRS-negative pigs immunized. 4 weeks after immunization, the immune pig virulent PRRS virus attacks. Results ,2-8 ℃ preservation 4,8,12 months of reproductive and respiratory syndrome vaccine did not significantly change the physical character, save the pigs at different time after the vaccination of more than 90% have access to protective immunity.
