Newly Discovered Molecule Could Reshape Swine Disease Management

Dr. Matheus Costa, Associate Professor at the Western College of Veterinary Medicine, and his research team have identified a powerful naturally occurring molecule that could change the game. This molecule not only kills bacteria—it also strengthens a pig’s immune response, helping it fight off multiple pathogens, including viruses and potentially even fungi.

The discovery emerged during trials focused on swine dysentery, a costly and persistent disease in global pig production.

All pigs in the study shared the same genetics, environment, and feed—but some remained resilient. Upon deeper investigation, the researchers found that these pigs carried higher levels of a specific peptide or protein—a naturally occurring molecule that appeared to be doing double duty: fighting off harmful bacteria and modulating the immune response.

A spring hike at Landons Bay in the Thousand Islands National Park with the Wandering Shepherds. We say goodbye to Ewetopia Farms for a few hours to take a sheep farming break and head out to enjoy the beauty of nature at a local hiking trail near our sheep farm. Spring has finally started with wild flowers poking their heads out along the trails. Also, lots of migrating swans, elusive snakes, and a curious chipmunk make today's wander special. So come take a hike with us as we explore a lovely park near Gananoque, Ontario, Canada.
