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, Gustavo Lima, PhD candidate at Iowa State University, explains how soybean meal net energy is evaluated using growth assays and calorimetry. He discusses caloric efficiency, validation under commercial conditions, and differences between controlled and real-world environments. Gustavo also highlights practical implications for diet formulation and ingredient valuation. Listen now on all major platforms!

“Indirect calorimetry provides a precise estimation of ingredient energy, yet validation under production conditions remains essential for accurate application in real systems.”
