Species targeted: Dairy;
Age: Young;
Outcome Parameter(s): Declining trend in resistance to most antimicrobials during and after policy changes
Summary: Based on feedback and interaction between study investigators, farm management and consulting veterinarians, a new policy was implemented to reduce antimicrobial use in calves. We investigated the effects of these policy changes in antimicrobial use on resistance in commensal Escherichia coli. In general, there was a declining trend in resistance to most antimicrobials during and after policy changes were implemented, except for ampicillin, ciprofloxacin, ceftiofur and gentamicin.
