Anything beyond that is a treat and should be given in limited quantities. Pellets should be fresh, and should be relatively high in fiber (18% minimum fiber).
Supplement. In scientific experiments, the use of controls allows to study one variable or factor at a time. It is, however, important that both the control and other (experimental) group(s) are exposed to the same conditions apart from the one variable under study.
The control is a variable held constant, thereby not being âvariableâ at all. The role of a control is to ensure that varying factors the scientist is not interested in and that would normally lead to changes in the dependent variable will not have an influence on the dependent variable in the experiment.
