The Crissey Zoological Nutrition Symposium

Theme: Micronutrients in Zoological Nutrition

December 7th & 8th, 2012

The Purpose of the Symposium

This is the seventh of a series of annual symposia to honor Sue Crissey's dedication and contribution to the discipline of zoological nutrition. The purpose of the symposium is to bring together professional zoological nutritionists, animal researchers, interested students and zoological clinicians to communicate advances in the discipline and examine the state-of-the-art approaches to important questions in zoological nutrition.

Crissey, a resident of Burgaw, North Carolina, was a valuable faculty member at the NC State College of Veterinary Medicine, and the Director of Nutrition for the Brookfield Zoo in Chicago at the time of her untimely death from ovarian cancer. She was a dynamic lecturer, meticulous researcher and reliable collaborator. Her contributions to our knowledge about the roles of nutrition in the health of both captive and wild animals of a wide variety of species have left a legacy and a model for young zoological nutritionists to emulate. This symposium is for professional nutritionists working with zoo animals, interested students, and, for the keynote address, the general public.

Program Chair: Eric van Heugten, North Carolina State University

Key Note Speaker

Iron chef EV.JPGEduardo V. Valdes, M,S.,Ph.D.
