Resumen
[EN] The welfare of an animal depends on its health and on the extent to what its biological needs
are met. Biological needs can be roughly divided into two main groups: (1) those related to
nutrition and physical and thermal comfort, and (2) those related to mental health and
behaviour, including a varied and stimulus-rich environment, a perception of control and
agency, and the possibility to engage in highly motivated behaviours. This paper will deal
with the importance of this last need for the welfare of farm animals. The term “behavioural
need” was defined a few decades ago based on motivational theory. The two main traits that
define a behaviour as a “behavioural need” are that (1) its onset depends mainly or solely on
internal factors, such as changes in hormone levels, and (2) its motivation only disappears
when the animal has performed the behaviour and therefore it is relatively independent of its
functional consequences. Several early studies on behavioural needs used the nesting
behaviour of sows as an example. As behavioural needs are controlled by internal factors -
as opposed to external stimuli-, their motivation is independent of the environment where the
animal is kept. Furthermore, animals must perform the behaviour, as otherwise its motivation
will remain high. More recently, the concept of “behavioural needs” has been criticized on the
grounds that many behaviours that do not fit its definition are still important for welfare, as
they contribute to the physical or mental health of animals. In this paper, the term “behavioural
need” will be used in a wide sense to refer to all behaviours that, independently of their
precise motivation, are important for welfare.
