Billy N. Day was born in Arthur, West Virginia. He received his B.S. degree (1952) and M.S. degree (1954) from West Virginia University and his Ph.D. degree (1958) from Iowa State University. He joined the University of Missouri (1958) as an assistant professor and was promoted to associate professor (1963) and professor (1968); at Missouri, he has been recognized as a top reproductive biologist. He has investigated the basic mechanisms involved in the control of reproductive processes in farm animals and has used the knowledge to develop management techniques for increasing reproductive efficiency in animals. Honors include Fred F. McKenzie Distinguished Professor of Animal Reproduction (1997-2000), Animal Physiology and Endocrinology Award (1982), Fellow Award (1993), and Morrison Award (1999).
