Bovine TB case in Sask. could have painful consequences

Jul 07, 2023

Two cows from a Saskatchewan ranch have tested positive for bovine tuberculosis, according to the Canadian Food Inspection Agency.

In February, the U.S. Department of Agriculture notified CFIA of a positive test for bovine TB in a tissue sample from a cow exported to an American feedlot from Saskatchewan in September 2022.

The herd of origin was tested in May, reactor animals slaughtered and two cases of bovine TB confirmed June 19.

The next steps could be painful for ranchers as CFIA officials begin to identify the origin of the infected cows and any contacts they may have had with other herds. Based on past circumstances, these measures have resulted in large-scale culling to stamp out the disease.

“The standard epidemiological approach will apply,” said Dr. Jamie Rothenburger, assistant professor at the University of Calgary’s faculty of veterinary medicine.

Video: Methionine Requirements for Lactating Sows - Cierra Kozole

In this episode of The Swine Nutrition Blackbelt Podcast, Cierra Kozole, PhD candidate in Swine Nutrition at the University of Guelph, explains how methionine supports lactating sows beyond milk protein synthesis. She discusses updated requirement estimates, source comparisons, methylation demand, and why modern sow genetics may require more precise amino acid strategies. Listen now on all major platforms!

"Methionine supports protein synthesis while also serving critical functions through methylation pathways that influence multiple biological processes."

Meet the guest: Cierra Kozole / cierra-kozole-772b64253 is a PhD candidate in Swine Nutrition at the University of Guelph in Canada. Her doctoral research focuses on refining estimates of methionine requirements for primiparous lactating sows, including evaluating methionine sources, nutrient partitioning, methylation reactions, and the links among amino acid supply, milk production, and sow protein retention.
