Monitoring protocols in boar studs are often insufficient to timely detect an infection.
The first goal of the project is to control PRRSv-infections in order to produce negative offspring.
A risk of airborne transmission of PRRSV is real, and air filtration can significantly reduce its risk. Area regional approach on PRRSV control/elimination indicates our direction where we should move forward in future.
About 50% of the vehicles used for transporting pigs in the United States are not washed between loads, so this article evaluates the ability of heating treatments to inactivate PRRSv present in manure-contaminated environments.
Clinical disease and outcome following PRRS infection has significant inherited components.
Is the right strategy to get a farm stable, that is, control clinical signs reducing the economic impact of the disease; or should a farm adopt strategies to go “negative”? As for other questions in the epidemiological field, our answer is “it depends”.
One of the challenges when conducting a disease elimination project is to ensure that the pathogen has in deed been eliminated from the herd.
