Antimicrobial Usage and Antimicrobial Resistance in Commensal from Broiler Farms: A Farm-Level Analysis in West Java, Indonesia.

Antimicrobial resistance (AMR) is a global public health threat, with antimicrobial use (AMU) in livestock recognized as a significant driver. This study examines farm-level AMU and AMR as well as the relationship between AMU and AMR on broiler farms in Indonesia. Data were collected from 19 farms in West Java between 2019 and 2021 to examine AMU in depth across four to five successive production cycles.

The comparison and use of tools for quantification of antimicrobial use in Indonesian broiler farms.

Introduction: Indonesia has a large broiler industry with extensive antimicrobial use (AMU) according to empirical evidence. However, there are no quantitative data of on-farm AMU. Quantification of AMU at farm level is crucial to guide interventions on antimicrobial stewardship (AMS).
