Reducing antibiotic use in livestock is a public health imperative, but the transition must be managed carefully to avoid increasing animal suffering from untreated disease.
Antibiotic reduction programmes create a tension between antimicrobial resistance prevention and animal welfare when the transition is not managed with sufficient investment in disease prevention. Animals should not pay the welfare cost of poorly planned antibiotic reduction through increased untreated illness. The best antibiotic reduction strategies improve underlying health through better housing, management and vaccination rather than simply withdrawing antibiotics without addressing root causes of disease.
