We convert surveillance results into useful information for participating feedlot producers and veterinarians, the Canadian beef industry, bovine practitioners, researchers, Public Health Agency of Canada, and other stakeholders (e.g., reports, infographics/fact sheets, webinars, podcasts).

Parenteral Antimicrobial Use in Canadian Feedlot Cattle CFAASP 2023

Share:
In 2023, AMU (antimicrobial use) data were collected from129,872 head of cattle in 393 randomly selected closed production lots from 26 finishing feedlots in AB, SK, and ON. Approximately 50% of the cattle were 1) calves vs. yearlings,2) steers vs. heifers, and 3) at high risk for bovine respiratory disease (BRD) on feedlot entry. Parenteral (injectable (4.5%), oral boluses (0.5%))antimicrobials represented 5% of all AMU. In 2023, parenteral AMU was similar in calves and yearlings although types of antimicrobials used varied. AMU increased in yearlings from 2019 to 2023.
