Basic Concepts
Defining Animal Welfare
“Animal welfare means the physical and mental state of an animal in relation to the conditions in which it lives and dies. An animal experiences good welfare if it is healthy, comfortable, well nourished, safe, is not suffering from unpleasant states such as pain, fear and distress, and is able to express behaviours that are important for its physical and mental state.” WOAH, 2019.
Human attitudes towards animals are very complex and influenced by a range of cultural, social, economic, and religious factors which manifest at individual and societal levels. Hence, animal welfare is directly linked to how humans interact with animals, especially those under their care. It has multiple dimensions including scientific, cultural, ethical, legal, social, political and financial which need to be considered.
Animal Welfare Frameworks
Initially, the focus of animal welfare was to avoid negative affective states (feelings), but it did not necessarily mean ensuring positive affective states. The current frameworks consider that animals should feel well, be biologically functional and live reasonably natural lives, all of which will not only reduce negative states but also provide animals the opportunity to have pleasant experiences and thus positive welfare states.
The Five Domains Model developed by David Mellor in 1994 is considered an evolution of the so-called Five Freedoms, in which four physical and functional domains – nutrition, health, environment and behaviour – influence the general mental state of the animal (the fifth domain), which results in the overall welfare state.
