Personal Information

Dr. Lemenager grew up on a livestock and grain farm. He currently has a cattle herd of his own with his two sons which keeps them connected as a family. His cow herd is an activity that makes him better at what he does. From a teaching and extension standpoint, he fights the challenges of beef producers (weather, forages, costs, production, and drought), and he uses his farm in beef production labs as a teaching opportunity.
