Associations among antimicrobial use, calf management practices,and antimicrobial resistance in Escherichia coli from a pooled fecalsample in calves on Canadian dairy farms: a cross-sectional study

  08 February 2024

The objective of this cross-sectional study was to determine associations between calf management practices, the number of antimicrobial treatments, and antimicrobial resistance in pre-weaned heifers on Canadian dairy farms. A composite of 5 fecal samples from preweaned calves was collected from 142 dairy farms in 5 provinces and analyzed for phenotypic antimicrobial susceptibility with the microbroth dilution method. Questionnaires were used to capture herd characteristics and calf management practices used on the farm. Calf treatment records were collected during the farm visits.
