Genetics against PRRS losses

A billion-dollar-plus disease problem demands more than wishful thinking, so we went straight to the genetics that keep pigs alive and growing when pathogens hit. With Dr. Jenelle Dunkelberger of Topigs Norsvin, we unpack the science and the on-farm relevance of breeding for disease resilience—how it’s measured, predicted, and proven in real barns. The conversation starts with new analysis on PRRS costs and moves quickly into what genomic selection can do for finding and scaling animals that sustain growth and cut losses under challenge.

We trace the story from customer reports of hardier terminal lines to c...
