Farm Animal Five Domains Welfare Assessment

The Five Domains model provides a comprehensive framework for assessing farm animal welfare across nutrition, environment, health, behavior, and mental state dimensions.

Key Facts

The Five Domains model was developed by Professor David Mellor as an update to the Five Freedoms framework
Mental state is the integrating domain that reflects the cumulative welfare impact of the other four domains
The Five Domains can be applied to any species and any production system for comparative welfare assessment
Positive welfare states are explicitly incorporated in the Five Domains unlike the original Five Freedoms

Welfare Considerations

The Five Domains model represents the current state of welfare assessment science. By integrating physical health, behavioral opportunity, and mental state into a single framework, it provides a more complete picture of animal welfare than any single indicator. The explicit inclusion of positive welfare alongside negative welfare makes it possible to assess quality of life rather than just the absence of obvious suffering.
