Livestock Antibiotic Alternatives: Current Evidence

Reducing antibiotic use in livestock farming requires effective alternatives that maintain animal health and welfare without contributing to antimicrobial resistance.

Key Facts

Probiotics and prebiotics show promise for improving gut health and reducing pathogen load in poultry and pigs
Phytogenic feed additives from herbs and plant extracts demonstrate antimicrobial and anti-inflammatory properties
Bacteriophage therapy offers targeted pathogen control without disrupting beneficial microbiomes
Organic acids in feed and water reduce pathogen levels in swine and poultry systems
Improved vaccination protocols have reduced therapeutic antibiotic needs by up to 50% in some systems

Welfare Considerations

The drive to reduce antibiotic use in livestock farming has a complex relationship with animal welfare. Antibiotics, when used appropriately, treat infection and reduce suffering. Over-reliance on prophylactic antibiotics, however, masks welfare problems that should be addressed through better management. Effective alternatives support welfare by maintaining health without contributing to resistance, while pushing farmers toward the root-cause improvements - better housing, nutrition, and biosecurity - that truly protect animal wellbeing.
