What is a priority and what is not? It depends on the risks and the PRRSV status of the farm…
We propose to use the processing fluids, the liquid accumulated at the bottom of the pail when farmers collect tails and testicles during routine procedures as a sample.
A study was performed including 69 PRRS-positive sow herds with the aim of comparing the use of PRRSV MLV and quarantine facilities with the PRRSV status of replacement gilts at first insemination.
Oral fluids are practical, fast, easy, cost-effective and reliable methods for sampling pig populations, but it has not been easy or practical to obtain such samples from suckling piglets...
Although the use of vaccination was effective in stabilizing the sows, the results of these case studies emphasized that elimination of PRRSV from the nursery can only be accomplished if vaccination and partial depopulation/ disinfection are supported by strict implementation of all recommended management procedures, including AI/AO.
The purpose of this study was to compare efficacy of LCE (load-close-expose) using attenuated PRRSV to that using live-virus exposure on breeding herds acutely infected with PRRSv.
The economic potential lost in a unit positive to PRRS could be around 35 – 37% of net unit margin.
