Abstract

My occupation is applied research and - funding arrangements being the force which drives such work - I am working with feedlot cattle at the moment. I have to find out whether they are unduly stressed and, if so, how to relieve it; also how much and what type of shade they require, and what are acceptable criteria of animal welfare. Like most research scientists, I also have a personal hobbyhorse which I can weave into my work. It is that stress affects the competence of an animal's immune system in subtle ways that have to do with its cognition. Alas, the plot thickens!
