Results Are In--Science to Inform Good Stewardship, from AMR to Grazing to Sanitation

What can the genetics of BRD at feedlots tell us about antimicrobial resistance?

There are clear differences in the antimicrobial resistance genes in bovine respiratory disease (BRD) pathogens in Canada compared to other places in the world, and while not directly related to antimicrobial use at feedlots, these could pose a risk of antimicrobial resistance (AMR) in the future independent of feedlot practices. These findings can all be used to inform surveillance and understand how specific feedlot practices are influencing AMR.

Has making antibiotics “prescription only” affected antibiotic stewardship on cow-calf operations?

Minimal changes to antimicrobial use have been observed since stricter regulations were imposed in December 2018. Antimicrobial use and resistance in the cow-calf sector pose limited risks to the health of humans, the environment or cattle. Proper antibiotic stewardship initiatives are essential to keep these risks low.
