Agribusiness Economics

With customizable programs and top-tier resources, our students explore the domestic and international economics of natural resource management. 

Animal Science

From farm to table and beyond – our students tailor their course of study to their interests.


Our students don’t mind getting their hands dirty. Neither does our faculty. In fact, it’s kind of a requirement.

Research and Farms

From our 2000 acre working farm system to the Shawnee National Forest, our students and faculty actively engage in creative and cutting-edge research.
