Routine antibiotic use in intensive livestock farming drives antimicrobial resistance while masking welfare problems. Reducing agricultural antibiotic use requires improving the welfare conditions that necessitate it.
The link between antibiotic use and animal welfare is bidirectional and important: poor welfare conditions create disease pressure that necessitates antibiotic use, and antibiotic use masks welfare problems that would otherwise incentivise improvement. Farms with high-quality housing, appropriate stocking density, good nutrition and careful stockmanship consistently achieve lower disease rates and antibiotic requirements. The Denmark example is instructive — a systematic reduction in antibiotic use, when accompanied by welfare improvements, maintained animal health without productivity loss. Reducing antibiotic use in livestock is therefore not just a public health imperative but a welfare improvement pathway, as it forces identification and correction of the underlying husbandry problems driving disease.
