Antibiotic stewardship programmes designed to combat resistance also have direct welfare implications — when used appropriately, antibiotics relieve suffering; inappropriate use undermines their future availability.
The tension between antibiotic stewardship and animal welfare is real and requires careful navigation. Antibiotics are essential medicines for relieving suffering in sick animals, and restricting access without improving underlying husbandry conditions that cause disease can increase welfare harm. The appropriate response to antibiotic reduction is not simply using fewer antibiotics in the same systems, but investing in the health conditions that reduce the need for treatment in the first place: better housing, lower stocking density, improved ventilation, vaccination, and pain management. Antibiotic stewardship programmes that combine usage reduction targets with investment in preventive health and welfare conditions achieve both objectives. The link between good animal welfare and low antibiotic dependency is increasingly well evidenced.
