The rapid development of antimicrobial resistance (AMR) in human health care urges the need for effective strategies to reduce antibiotic use in animal production.The Netherlands and Denmark have already implemented successful strategies to reduce antibiotic usage in animal production, which includes the EU ban on antimicrobial growth promoters in 2006 and various additional measures to lower prophylactic and therapeutic use.In the Netherlands, an encouraging reduction in prevalence of Extended Spectrum Beta Lactamase (ESBL) producing E.coli in broilers has been observed.Part of the success of the reduction in antibiotic use may be attributed to the wide application of selected feed additives and combinations thereof targeting intestinal microbiota and immunity.The toolbox includes for example organic acids, pre-and probiotics, phytochemicals and enzymes.Productivity and health responses can be obtained in animals similar to those reported for antimicrobial growth promoters by improving microbiological quality of drinking water and feed,stabilization of the intestinal microbiota and enforcement of the mucosal barrier of the host.Such strategies have also shown the potential to lower the prevalence of Salmonella in poultry and swine production.Regulatory recognition of the prophylactic effects of feed additives in animal health should further facilitate the progress to reduce AMR.
