A breakthrough in animal genetics may reshape the future of pork production by reducing disease pressure, antibiotic use and environmental impact—while improving profitability.
Porcine Reproductive and Respiratory Syndrome (PRRS), identified more than 30 years ago, continues to be one of the most devastating diseases in global pork production. It affects roughly 60% of the North American sow herd and costs the industry an estimated $1.2 billion annually, with economic losses continuing to grow.
PIC, in partnership with leading university researchers, has developed a PRRS-resistant pig through precision gene editing. This advancement targets a specific protein required for the PRRS virus to infect pigs. By removing a portion of that protein, the animal is rendered resistant to the virus—offering a promising new tool in disease control.
This innovation will be a key topic of discussion at the upcoming Saskatchewan Pork Industry Symposium 2025 in Saskatoon.
A Turning Point for the Industry
Lindsay Case, Director of New Product Commercialization at PIC, says the PRRS-resistant pig presents a rare opportunity to tackle multiple industry challenges simultaneously.
“Producers are being asked to improve animal welfare, reduce antibiotic use, minimize environmental impact and enhance productivity—all while maintaining profitability,” says Case. “This technology has the potential to address each of those priorities at once by reducing disease pressure at its source.”
Industry Implications
-
Animal Welfare: Reduced disease incidence means better overall herd health.
-
Reduced Antibiotics: Improved resistance could dramatically decrease the need for therapeutic treatments.
-
Environmental Benefits: Healthier pigs grow more efficiently, lowering overall resource use.
-
Profitability: Lower mortality, improved feed conversion and fewer production losses could drive long-term economic gains.
