When Marshall Ruble started as manager of the beef teaching farm as a new Iowa State grad, he figured he'd stay three or four years. It's now been nearly 33 years, mentoring hundreds of students to care for the farm's herd. The farm provides cattle for 11 under-graduate courses, industry events such as scholarship contests, livestock judging, artificial insemination schools, ultrasound training and ultrasound certification. "If we can help promote animal agriculture we want to be a presence. We are involved in a few research projects if it doesn't affect our primary directive of undergraduate teaching," he adds. Ruble ('78 animal science) is a native Iowan raised on a diversified livestock farm near Corydon. He especially loves beef cattle, although he's taken care of sheep, swine, horses, chickens and dairy cattle.
