New research forecasts significant economic and market impacts with PRRS-resistant pig adoption

In April 2025, PIC was granted approval by the FDA for the gene edit used in its PRRS-resistant pig, an extraordinary step forward in eliminating challenges from one of the most serious global pig diseases. 

Now, research published in the August 2025 American Journal of Veterinary Research has revealed a model of potential global economic and market impacts associated with adoption of this new technology.1

PIC commissioned Dr. Jayson Lusk, Vice President and Dean of Oklahoma State University’s Division of Agricultural Sciences and Natural Resources and Regents Professor, to develop the economic model used in the research.
