The scientific case for farm animal sentience has profound ethical implications for how we design and regulate livestock production systems.
The recognition of farm animal sentience transforms the ethical framework for livestock production. Sentient beings are morally considerable — their suffering matters and positive experiences have value. This means that welfare is not merely a nice-to-have production factor but a fundamental ethical obligation. Strengthening the policy and cultural response to the evidence of farm animal sentience is one of the most important animal welfare challenges of our time.
