The Five Domains model has replaced the Five Freedoms as the leading framework for comprehensive animal welfare assessment. Understanding it helps practitioners and advocates apply welfare science effectively.
The Five Domains model represents the current state of art in animal welfare assessment. Building on the Five Freedoms framework from the 1970s, it provides a more nuanced and scientifically grounded approach that explicitly incorporates animal mental state as a welfare dimension. The model recognizes that welfare exists on a continuum from severely negative to highly positive, and that the goal of welfare management is not merely avoiding harm but actively promoting positive states. By examining nutrition, environment, health, behavior, and mental state as interacting domains, it identifies how welfare problems in one domain affect others and guides holistic welfare improvement. The Five Domains is now widely used in zoo, farm, and companion animal welfare assessment globally.
