Understanding the genetics behind antimicrobial resistance in beef cattle Researchers are trying to establish relationships between resistance genes in beef cattle25 March 2024 25 March 2024 3 minute read 3 minute read By: By: University of Saskatchewan North AmericaResearchers at the University of Saskatchewan Western College of Veterinary Medicine (WCVM) are investigating antimicrobial resistance by establishing relationships between antimicrobial resistance genes in beef cattle and examining the impact of various exposure events on patterns of antimicrobial resistance. Antimicrobial resistance is a major concern in the cattle industry as the animals develop resistance genes to the various antibiotic drugs, which leads to limited treatment options for livestock producers. In the end, researchers can use this to inform future management decisions surrounding antimicrobial resistance patterns in beef cattle. Increased legislation in Canada that’s aimed at curbing antimicrobial resistance has also limited producer options by stipulating which antimicrobials can and cannot be used. The researchers are optimistic that their work to identify these resistance patterns can prevent further resistance challenges and help producers to make informed beef cattle management decisions.
