The article addresses the issue of moral concern for domestic animals and for animal welfare defined as freedom from mortality and morbidity, freedom from stress, and the animal's freedom to express the natural behaviour of its species. While the first two definitions can lead to a failure to consider the animal in all its aspects, the third has the advantage of achieving this, taking into account the needs and social behaviours of livestock.

The closely associated concepts of welfare and stress may be considered as opposites since welfare cannot be achieved under stress and vice versa. Stress was first considered as an unspecific response to any challenge taxing the organism's resources where the HPA axis plays a central role. Along the same lines, welfare was considered as the state of an individual on a continuum between poor and good depending on the efforts required to adapt to the environment. However, these views cannot explain opposite results such as up- vs. down-regulation of the HPA axis and hypo- vs. hyper-behavioural reactivity under chronic stress. ... It is therefore suggested that the discrepancies found in the literature in terms of responses of the HPA axis or modification of behaviour under aversive conditions may stem from differences in the way a situation is evaluated. It is argued that stress comes from the animal's evaluation of the outcome of a situation, and that welfare is the state resulting from that evaluation.
