Purpose
In the former simultaneous test, the result showed MIIP induced the generation of the IgA for protection, which reduced the ELISA antibody titer. In order to confirm the immune response, the trial was conducted in a PRRS ELISA antibody positive pig farm to observe the effectiveness of MIIP.
Trial Place
PRRS-outbroken farrow-to-finish farm in Xiaying District, Tainan, Taiwan.
The objects
8-week-old pigs
Condition
PRRS got outbreak in the farm, and PRRS ELISA antibody of the 8-week-old pigs showed 100% positive before the trial. Then treated with MIIP for 5 months, and 2 months cessation.
The result
The table showed that after the 5 months using, the positive ratio declined to 20%. However, after 2 months of cessation, the positive rate rebounded to 100%.
Accordingly, the farm was surrounding by PRRS virus. But, after the long term of MIIP treatment, PRRSV was blocked by the specific IgA, significantly reduced the pressure of infection. However, the pigs would infect by PRRSV around environment without MIIP protection.
Conclusion
MIIP will inhibit the environmental PRRSV and prevent the outbreak of the PRRS.
