Farmers' knowledge and expectations of antimicrobial use and resistance are strongly related to usage in Dutch livestock sectors.

Comprehensive strategies to improve on-farm antimicrobial use (AMU) are needed to contain antimicrobial resistance (AMR). Little is known about farmers' motivating and enabling factors, and about their influence on AMU.
