Responsible antibiotic use in cattle is both a welfare and public health priority. Evidence-based stewardship reduces resistance while ensuring sick cattle receive effective treatment.
Antibiotic stewardship in cattle farming is inseparable from animal welfare. Effective antibiotics are essential tools for treating bacterial diseases that cause significant suffering — bovine respiratory disease, mastitis, metritis, and footrot all require antibiotic treatment for welfare-appropriate management. The development of antibiotic resistance threatens to render these treatments ineffective, creating a future welfare crisis where currently treatable diseases become untreatable.
The welfare imperative is thus twofold: use antibiotics when animals are genuinely sick to relieve suffering, but avoid unnecessary use that promotes resistance and risks compromising future treatment efficacy. This means using culture and sensitivity testing to guide antibiotic selection, completing treatment courses, avoiding prophylactic mass medication, and implementing preventive measures that reduce the need for antibiotic treatment.
The transition from blanket to selective dry cow therapy is the most significant antibiotic reduction in dairy farming. Rather than treating all cows at drying off, selective DCT treats only cows with identified mastitis risk based on SCC history and bacteriological testing. This substantially reduces antibiotic use while maintaining therapeutic efficacy and cow welfare — cows requiring treatment still receive it; those that don't, don't.
