The high genetic diversity of the virus is not only complicating laboratory tests but also the estimation of the level of protection of pigs against PRRSV.
An example on how technology can be implemented in a farm for evaluation of biosecurity compliance using production parameters.
Do outbreaks in the same farm have a similar time-to-stability? What factors can affect time-to-stability?
71% of the farms reporting a PRRS break today will report a break within the following two years. What makes them more susceptible?
PCR can detect the virus in virtually any material but, does it mean the sample contains the virus and it is infectious? Is any PCR test valid for any strain?
How can we monitor our program? Which pigs should be sampled? How many? How often should we sequence the virus/es present in our farms?
Four veterinarians talk about gilt acclimation: programs they put in place, how the immune status is measured and special management scenarios for introducing those gilts into the main herd.
What is the preferred exposure method?, and the best status of the incoming gilts?, should they be raised on-farm or purchased?, … Veterinary practitioners from Germany, North America, China, and Spain share their opinions.
