Document Summary

There are four different classes of evidence that can be used to assess welfare, but some classes give more powerful evidence than others. Assessing animal welfare: health, production / productivity, physiology / biochemistry, behaviour. In spite of all the fine preceding arguments about the differences between being ill and feeling ill, when it comes to assessing welfare, we simplify and say that: health is necessary but not sufficient. Certainly if an animal can be seen to be ill, there is no doubt that its welfare will be reduced. The productivity argument, which is often heard, is usually some variation on: They must be happy, look at their production! . There are some problems associated with this argument. The first is that production / productivity can be measured in many different ways. All of these measures would give different answers and therefore different estimates of the state of welfare.
