sow vaccination – Swine in Minnesota

Experimental in-vitro evaluation of PRRSv modified-live vaccine and wild-type virus sequence detection in co-infections

This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.

In this week’s science page UMN Veterinary Population Medicine researchers Joaquin Alvarez-Norambuena, Mariana Kikuti, Albert Rovira and Cesar Corzo investigate the detection of wild-type or modified-live vaccine sequences in in-vitro samples.

Effect of influenza A virus sow vaccination on infection in pigs at weaning: A prospective longitudinal study

Dr. Chamba Pardo and colleagues from the University of Minnesota share results of the implementation of sow vaccination to control influenza infections in pigs at weaning through a special issue article published in Transboundary and Emerging Diseases.

Highlights

Sow vaccination against IAV was effective at reducing the number of infected groups of pigs at weaning, and the number of positive nasal swab pools within a group.
Both prefarrow or whole herd vaccination protocols, and use of commercial or autogenous inactivated vaccines, yielded significant and similar reduction of IAV infections in pigs at weaning.
Sow vaccination can help control IAV infections in pigs at weaning and, thus, minimize transmission to growing pigs and other farms.
