This fund was formed to recognize the contribution of Dr. Billy Day to the field of reproductive physiology and to the American Society of Animal Science. Money from the club is used yearly to support the Billy Day Symposium at the ADSA-ASAS Midwest Meeting.

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).

Value of club as of 9/30/11: $13,116.48

Approximate Total of Donations and Pledges to the Club since inception: $25,000
