"Professor Clark is only the second person to receive this significant award," noted Neal Merchen, head of the Department of Animal Sciences. "This award is intended to recognize individuals like Clark who have made repeated and sustained career-long contributions that have changed the knowledge base in the science of animal nutrition."
Merchen added that Clark's award, combined with others in recent years to his colleagues, demonstrates the leadership role of the U of I and the department in the fields of animal sciences.
Clark, who retired in 2003, continues to come to his office everyday, conduct research, and teach an undergraduate seminar course.
He joined the U of I faculty in 1968 after earning his undergraduate degree at Murray State University in Kentucky and his Ph.D. at the University of Tennessee. Clark has mentored nine Ph.D. students, 17 Masters of Science students, and 13 post-doctoral research associates.
The award committee noted that his concepts of feeding lactating dairy cows are utilized throughout the world. His research has focused on nitrogen, carbohydrate, and lipid nutrition; the use of bST (growth hormone); and the feeding value of high moisture corn and biotech crops.
Shortly before his retirement, Clark participated in the effort that led to new standards for dairy cow nutrition that were issued by the National Academy of Sciences.
