The Five Domains Model provides a comprehensive framework for assessing farm animal welfare across nutrition, physical environment, health, behaviour, and mental state. Its practical application is transforming welfare auditing.
The Five Domains Model represents a genuine conceptual advance in animal welfare science by explicitly incorporating positive welfare as a goal, not merely the absence of suffering. Under the Five Freedoms framework, welfare was achieved by eliminating negative states; under Five Domains, welfare is maximised by creating conditions for positive experiences as well as minimising negative ones. In practical auditing, this means assessing not just whether animals are free from disease (health domain) but whether they have opportunities for positive social interaction, play, and exploration (behaviour domain) that contribute to positive mental states. The model's integration of 'mental state' as an explicit domain forces consideration of subjective animal experience, not just observable behaviour or physical condition. This alignment with contemporary animal sentience science makes Five Domains the appropriate framework for 21st-century welfare assessment.
