The development of the animal after birth is marked by complex changes. Certain periods are particularly important and have been defined as "critical periods" (Krecek, 1971). Two processes are important to the survival of the animals during these times.

The process of "tolerance" renders the neonate relatively unresponsive to a stressor as compared to the adult and protects the animals from over-responding the depleting vital resources until it is physiologically mature.
