The tension between using antibiotics to treat sick animals and preserving antibiotic efficacy for future use creates genuine welfare trade-offs that require careful ethical consideration.
The ethics of antibiotic use in livestock presents a genuine dilemma between the welfare of individual animals and the collective welfare of future animals and humans threatened by resistance. A pragmatic welfare approach supports effective treatment of individual sick animals while strongly opposing prophylactic and growth-promotion uses. The evidence that well-managed herds can maintain good welfare with dramatically reduced antibiotic use shows that the trade-off is often false: better management replaces rather than withdraws treatment.
