While ongoing surveillance and research initiatives have provided some information on antimicrobial use (AMU) in many livestock commodities, there are no recent reports for Canadian cow-calf herds. Antimicrobial use data were collected in 2014 for bulls, cows, and calves from 100 herds participating in the Western Canadian Cow-Calf Surveillance Network. Lameness was the most common reason for treatment in cows and bulls, with oxytetracycline being the treatment of choice. Herd owners were most likely to treat calves before weaning with florfenicol, oxytetracycline, and sulfamethazine for respiratory disease or diarrhea. The most frequently reported reason for antimicrobial use in weaned calves was respiratory disease and the most reported product was florfenicol. While 98% of herds reported treating ≥ 1 animal with antimicrobials, most cattle did not receive antimicrobials for either treatment or disease prevention on participating cow-calf operations.
虽然正在进行的监测和研究项目已经提供了许多家畜品种抗菌药物使用（AMU）的一些信息，但目前尚无关于加拿大母牛-犊牛群的近期报告。2014年收集了参与加拿大西部母牛-犊牛监测网络的100个牛群中公牛、母牛和犊牛的抗菌药物使用数据。跛行是母牛和公牛最常见的治疗原因，土霉素是首选治疗药物。牛群所有者最有可能在断奶前用氟苯尼考、土霉素和磺胺二甲嘧啶治疗犊牛的呼吸道疾病或腹泻。断奶犊牛使用抗菌药物最常报告的原因是呼吸道疾病，最常报告的产品是氟苯尼考。虽然98%的牛群报告用抗菌药物治疗≥1头动物，但在参与的母牛-犊牛养殖中，大多数牛未接受用于治疗或疾病预防的抗菌药物。
