Although the Five Freedoms paradigm has been very influential in shaping animal welfare thinking for the last two decades, it has two key disadvantages. First, the focus on “freedom” from a range of negative experiences and states has been misunderstood in a number of quarters to mean that complete freedom from these experiences and states is possible, when in fact the best that can be achieved is for them to be minimised. Second, the major focus of the Freedoms on negative experiences and states is now seen to be a disadvantage in view of current understanding that animal welfare management should also include the promotion of positive experiences and states. The challenge therefore was to formulate a paradigm that overcame these two main problems and yet was straightforward enough to be accessible to non-specialists, including members of the lay public who are interested in animal welfare. This was achieved by highlighting the Five Provisions, originally aligned with the Five Freedom

Throughout its 25-year history, the Five Domains Model for animal welfare assessment has been regularly updated to include at each stage the latest authenticated developments in animal welfare science thinking. The domains of the most up-to-date Model described here are: 1 Nutrition, 2 Physical Environment, 3 Health, 4 Behavioural Interactions and 5 Mental State. The first four domains focus attention on factors that give rise to specific negative or positive subjective experiences (affects), which contribute to the animal’s mental state, as evaluated in Domain 5. More specifically, the first three domains focus mainly on factors that disturb or disrupt particular features of the body’s internal stability. Each disturbed or disrupted feature generates sensory inputs which are processed by the brain to form specific negative affects, and these affects are associated with behaviours that act to restore the body’s internal stability. As each such behaviour is essential f
