Abstract

Antimicrobial resistance, and the potential for transmission of resistant zoonotic pathogens from animal sources to humans, continues to be a heavily debated topic. We need to improve our understanding of factors on dairies that contribute to the development or shedding of resistant pathogens, so that veterinarians and producers can adopt judicious drug use and animal management practices that will ultimately protect both animal and human health. The objective of this study was to describe the relationship between the type of milk diet fed, age of calf, and systemic treatment with antimicrobials, and levels of antibiotic resistance in fecal E. coli from dairy calves between birth and four months of age.
