With advances in genetics and livestock practices, the beef industry has evolved over the years. However, current references for vitamin and mineral inclusion are outdated, failing to address the animals' modern needs. Our guest (and also our co-host!), Dr. Stephanie Hansen, a prominent researcher and professor in feedlot nutrition at Iowa State University, focuses on optimizing growth and stress resilience in cattle. Dr. Hansen's research has revealed interesting links between beta-agonists like ractopamine hydrochloride and reduced external fat in cattle, benefiting both the industry's economic viability and sustainability. These findings emphasize the importance of up-to-date research to meet the changing demands of livestock production.

"I wanted to ensure that animals wouldn't get sick, and I was eager to explore ways to prevent illnesses in them." - Dr. Stephanie Hansen
