Use of processing fluids for PRRSV diagnostics

Reprinted as posted on UMN Swine Disease Eradication Center's Swine in Minnesota blog.

During the last few years, the improvement of sampling and diagnostics techniques has made sampling at the farm aneasier task. The use of blood pooling techniques and oral fluids are two examples of those improvements. However, veterinarians and producers are always looking for more sensitive, cheaper and quicker techniques for sampling herds. One of the ways of achieving these goals would be to use routine chores, such as piglet processing, since castration and tail docking are part of the regular procedures in sow farms. We propose to use the processing fluids (PF), the liquid accumulated at the bottom of the pail when farmers collect tails and testicles during routine procedures, as a sample. The goal of this study was to evaluate the accuracy of the processing fluids by real-time PCR to assess Porcine Reproductive and Respiratory Syndrome virus (PRRSV) status in a sow herd.
