Once the first symptoms of the infection emerged in pigs the facility was locked and the possibility to get in from outside was the only used.
This article shows the different measures taken and the strategy followed to eradicate PEDv in a commercial farm: stabilization, creation of a disinfection bubble, monitoring and verification.
We were called for clinical problems on weaners that appeared a few days after a feed transition in a farrow-to-finish farm: swelling of the eyelids and forehead, incoordination, dyspnea and sudden death.
The owner contacted us because he has seen a reduction in performance in recent months, although no decline has been identified in any particular parameter. He says that, overall, “the sows are doing worse".
This case report highlights the importance of a comprehensive approach to achieve a correct differential diagnosis.

The prevalence of Mycoplasmal pneumonia and pericarditis lesions was significantly higher in pigs weaned at lower weights compared to their heavier cohorts, despite the provision of a superior production system for the lower weight group.
The farm reports a problem of low prolificacy (mean annual live births of 11.91) and low fertility in summer, with a marked increase in acyclic returns.
The farmer, alarmed, calls us describing a clinical picture of abortions in the last third of gestation, weak newborn piglets, stillbirths, mummified piglets, agalactia, sows with fever and small litters.
