The Science of Animal Welfare

Book excerpt: In many people's eyes, the ability for animals to be able to behave 'naturally' is essential for their welfare. However, animals do not necessarily want to do behaviour just because it is 'natural' or is seen in wild animals. Being chased by a predator is not necessarily good for welfare. Natural behaviour is important because it gives us a baseline for what animals might want to do but it cannot define good welfare on its own. It has to be validated in exactly the same way as other behavioural correlates of welfare, as either contributing to health or being what the animals want to do.
