Antimicrobial resistance is a global threat for both human and animal health. One of the main drivers of antimicrobial resistance is inappropriate antimicrobial use in livestock production. The aim of this study was to examine the technical and economic impact of tailor-made interventions, aimed at reducing antimicrobial use in broiler production. Historical (i.e., before intervention) and observational (i.e., after intervention) data were collected at 20 broiler farms. Results indicate that average daily gain and mortality generally increased after intervention, whereas feed conversion and antimicrobial use decreased. Economic performance after interventions was generally higher than before the interventions. Sensitivity analyses on price changes confirm the robustness of the findings.

旨在减少肉鸡场使用抗生素的兽医干预措施的技术和经济影响。

抗菌素耐药性是对人类和动物健康的全球威胁。抗菌素耐药性的主要驱动因素之一是在畜牧生产中不当使用抗菌素。本研究的目的是检查量身定制的干预措施的技术和经济影响，旨在减少肉鸡生产中抗菌素的使用。在 20 个肉鸡场收集历史（即干预前）和观察性（即干预后）数据。结果表明，干预后平均日增重和死亡率普遍增加，而饲料转化率和抗菌素使用量下降。干预后的经济表现普遍高于干预前。对价格变化的敏感性分析证实了调查结果的稳健性。
