Physiology.

The assessment of animal welfare using physiological parameters depends on the measurement of change(s) in biological function(s) in response to stressors. This complex biological response is commonly called the 'stress response' and has been repeatedly conceptualized since homeostasis was first formulated. This chapter first examines the changing concept of stress, describing how it has evolved from a reference to the physiological responses involved in adaptation to the environment, to the animal's state when it is challenged beyond its behavioural and physiological capacity to adapt to its environment. Next, the interactions between physical stress and emotional stress, as well as the interaction between emotional status and physiological responses to stress, are considered. Examples of different sources of stress and their biological consequences are then provided to illustrate the interplay between biological systems which constitutes the response to stress. We discuss the limitations of the physiological parameters that are currently used, and some that could potentially be used, to assess the response to stress. We conclude that the assessment of animal welfare using physiological parameters is useful, but is still evolving owing to both technological advances and progressive change in the concept of stress.
