Preventing the spread of PRRSV within and between pig populations is a critical component of a farm’s disease control program. To aid in controlling the spread of this agent, this manual provides a summary of data from experiments conducted from our group at the University of Minnesota that were specifically designed to identify the routes of PRRSV transmission and to develop protocols of biosecurity to reduce this risk. All protocols have been, and continue to be validated during an–going experiment that has been in process over the past 2 years at our Swine Disease Eradication Center (SDEC) production region model farm.
