Livestock Antibiotic Stewardship: Welfare and Resistance

Antibiotic stewardship in livestock preserves treatment effectiveness for future generations while supporting animal welfare through targeted use when animals genuinely need treatment.

Key Facts

Antimicrobial resistance (AMR) threatens both animal and human medicine through loss of effective treatments
Livestock use represents approximately 70% of global antibiotic consumption in some countries
Prophylactic use of critically important antimicrobials is now banned or restricted in many jurisdictions
Targeted, therapeutic antibiotic use that treats sick animals is welfare-essential and consistent with good stewardship
Metaphylactic treatment (treating all animals in a group when some are sick) may be appropriate with veterinary guidance
AMR development means future sick animals may have fewer effective treatment options, a long-term welfare concern

Welfare Considerations

Antibiotic stewardship creates a tension between immediate welfare (treating sick animals) and long-term welfare (preserving effective treatments for future animals). The welfare-optimal approach is clear: treat sick animals appropriately and promptly, use targeted antibiotics rather than prophylactic broad-spectrum drugs, and invest in prevention to reduce the need for treatment. This approach serves both current and future animal welfare while protecting public health from AMR.

What You Can Do

Work with your herd vet to develop a written medicine policy that guides appropriate antibiotic use decisions
Prioritize vaccination and management improvements that reduce the need for antibiotic treatment
Use culture and sensitivity testing to select the appropriate antibiotic rather than defaulting to broad-spectrum drugs
Treat sick animals promptly and appropriately — delayed treatment for welfare reasons is not good stewardship
Report antibiotic use accurately and use this data to identify patterns that might be reduced
Support research into non-antibiotic alternatives including vaccines, probiotics, and management interventions
