The heart beats faster so that oxygen can be pumped more quickly to the tissues that need it. The liver releases sugar to fuel the muscles that will be used for fighting or running. This all happens very quickly, in a matter of a few minutes or seconds and Cannon  called it the 'General Emergency Reaction'. It is due to the activation of a special part of the nervous system, the sympathetic nervous system and of hormones such as adrenaline and noradrenaline.
However, this may well be because there is no time for serious health defects to make themselves shown. The animal may soon be released or the journey may soon be over. One reason for supposing that, given time, the animal's health would be affected is that it is often possible to detect physiological disturbances such as changed hormone levels which, as we will discuss more fully in Chapter 5, may be the precursors of ill-health. Sometimes, indeed,· capture and transport, do cause weight loss, bruising, injury and physical deterioration so severe as to lead to death (Hails ).
But before we get on to this, we must first make a very clear distinction between the health of an individual animal and the 'productivity' of farm animals. It is very easy to be misled into thinking that these two are the same and that, say, a 'productive' farm must be full of healthy hens all laying large numbers of eggs. Such a confusion is, as we shall see, extremely dangerous, all the more so because it is frequently argued that the high productivity of intensively managed farm animals shows that they cannot possibly be suffering.
