A typical experimental format involves evaluating the response caused by application of different treatments to experimental subjects (animals, carcasses pens, pastures, etc.). The effect of a given treatment might be evaluated by comparison t o a control group or to one or more other treatment groups. However, a problem with animal research (and other types as well) is that variation not due to treatments often exists among experimental subjects.
