Students may develop an understanding of animal biology and discover ways to address local and global issues facing animal industries. This is a great field of study for those interested in animal management.

A Doctorate of Philosophy, or PhD, may require eight years or more to complete, as well as a dissertation. In most fields, the possession of a PhD qualifies the holder to become a professor of a chosen subject. There are many different programs available.
