Abstract: The study objectives were to describe antimicrobial use (AMU) and Salmonella resistance on 90 Alberta swine farms.The vast majority of antimicrobials were used in-feed.In weaners, in-feed use did not vary among farms, suggesting heavy reliance on in-feed antimicrobials.For grow-to-finish production phases, most farms reported heavy reliance on in-feed antimicrobials, but 6 and 14 farms did not report any in-feed AMU in growers and finishers, respectively.The tetracycline-sulphametazinepenicillin combination and carbadox were the most common antimicrobials added to the weaner rations, while tylosin and lincomycin were the most common antimicrobials added to grower and finisher rations.No resistance was observed to nalidixic acid, ciprofloxacin, amikacin and ceftriaxone.A low frequency of resistance (<5%) was observed to gentamicin, apramycin, cephalotin, ceftiofur, amoxicillin/clavulanic acid and trimethoprim-sulphamethoxazole.Most common resistances were detected to tetracycline, streptomycin, sulphamethoxazole, kanamycin and ampicillin.Despite widespread AMU, 40.19% of Salmonella isolates were susceptible to 17 antimicrobials.
