Canadian ‘super pigs’ threaten to invade US

Amass of Canadian ‘super pigs’ are threatening to breach the US border, but northern states are putting tactics in place to stop this wild hog invasion.

Super pigs have appeared in Alberta, Saskatchewan, and Manitoba in Canada after crossbreeding between different pig species created their super-swine form.

The pigs have been destroying crops and degrading water quality, but there is no stopping these feral hogs as they also can breed excessively and continue to multiply in their masses, according to the University of Saskatchewan.

“Wild pigs are ecological train wrecks. They are prolific breeders, making them an extremely successful invasive species,” said Ruth Aschim, a PhD student from the university who led research on the super pig species.

The researchers called the mutant wild pigs “the most prolific invasive mammal in Canada.”

The US already has a massive issue with feral hog populations, costing landowners billions each year in crop and land destruction, so northern states like Minnesota, North Dakota and Montana are taking action to stop the super pigs encroaching on US territory.

Ryan Brook, a professor at the University of Saskatchewan and expert on the growing super pig population, said that Montana has already banned raising and transporting wild pigs into the state.

In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Kwangwook Kim, Assistant Professor at Michigan State University, discusses the use of non-nutritive sweeteners in nursery pig diets. He explains how sucralose and neotame influence feed intake, gut health, metabolism, and the frequency of diarrhea compared to antibiotics. The conversation highlights mechanisms beyond palatability, including hormone signaling and nutrient transport. Listen now on all major platforms!

“Receptors responsible for sweet taste are present not only in the mouth but also along the intestinal tract.”

Meet the guest: Dr. Kwangwook Kim / kwangwook-kim is an Assistant Professor at Michigan State University, specializing in swine nutrition and feed additives under disease challenge models. He earned his M.S. and Ph.D. in Animal Sciences from the University of California, Davis, where he focused on intestinal health and metabolic responses in pigs. His research evaluates alternatives to antibiotics, targeting gut health and performance in nursery pigs.
