AMERICAN ASSOCIATION OF ZOO VETERINARIANS “Dedicated to wildlife health and conservation” 581705 White Oak Road Yulee, Florida, 32097 904-225-3275 Fax 904-225-3289 Dear Esteemed Colleagues, Welcome to warm and sunny Orlando for the 46th annual gathering of the American Association of Zoo Veterinarians (AAZV) for fun, frivolity and some very, very serious learning. This year we will continue the long standing tradition of providing an outstanding educational program to expand your minds and enhance your skills in order to benefit the endangered species, and the more common ones, that we care for. The AAZV has been holding annual educational conferences in this challenging field for forty- five years. These meetings afford us the opportunity to share experiences, learn from each other and to deepen and broaden our knowledge base. However the AAZV is busy throughout the year providing new knowledge through the Journal of Zoo and Wildlife Medicine as well as providing valuable services for you, our members. The organizations membership and financial status remain stable and improving a bit each year. The diverse committees of the AAZV including the executive committee, continue to work hard to keep the organization vigorous, healthy and responsive to the needs of the members. We continue to benefit from the outstanding organizational talent and hard work of Pam Brownlee, Adine Nicholson and Dr. Rob Hilsenroth working from our global headquarters at White Oak, an organization which we are deeply appreciative towards for their support. Our thanks to the scientific program committee headed up by Dr. Deena Brenner and Dr. Meg Sutherland-Smith who have put together an outstanding program of great speakers and challenging topics. Our thanks also to the American College of Zoological Medicine for sponsoring the continuing education credits for this conference. And finally our thanks to our hosts, Disney’s Animal Kingdom for a fabulous venue in which to hold our conference! Learn much, build new relationships and enjoy the camaraderie here in this great location for the 2014 AAZV Conference. Sincerely, Douglas L. Armstrong, DVM President, American Association of Zoo Veterinarians Dear Colleagues and Friends, On behalf of the Scientific Program Committee (SPC), I have the great pleasure of welcoming you to the 46th Annual Conference of the American Association of Zoo Veterinarians (AAZV). The members of the SPC, Jessica Siegal-Willott, Deena Brenner, Susie Bartlett, Allison Tuttle, Meg- Sutherland-Smith, and Kelly Helmick have dedicated tireless hours to make this year’s conference a success, along with our gracious local hosts at Disney’s Animal Kingdom led by Scott Terrell and Deidre Fontenot. The conference program continues to evolve each year based on your feedback. Our 27 session chairs had the arduous task of selecting from the over 251 submitted abstracts to develop 13 scientific sessions. These sessions are filled with cutting-edge presentations and represent a blend of taxa and discipline based themes. An additional 39 posters will present fascinating research and clinical medicine. As a new offering this year, a conservation session has been focused on a single taxa this year to facilitate expert commentary and discussion. This year’s focus is on bears and will change annually. Several featured speakers will present focused lectures throughout the week on important topics ranging from elephant tusk repair to anesthetic monitoring. The Advanced Topics sessions continue this year with a variety of advanced clinically relevant topics. Finally, a panel discussion will foster dialogue on the recently hot topic of management based euthanasia, followed by a featured speaker discussing the current state of zoos and aquariums in a changing media landscape. Twenty-five hours of continuing education credit is available this year, sponsored by the American College of Zoological Medicine. The 15 amazing workshops being offered this year allow for up to an additional 25 hours of credit. Drawing attention to one unique offering this year, AAZV has partnered with the Disney Institute to create a full-day leadership development workshop. This program will provide professional development focused on the non-clinical aspects of the veterinarian’s role in modern zoos and aquariums. Representing a blend of hands-on, clinical medicine and in-depth didactic presentations – we hope everyone finds a workshop that appeals to their educational needs. The SPC always welcomes your feedback through the conference survey to help us continually enhance and grow the program each year! We would like to gratefully acknowledge the tireless efforts of Rob Hilsenroth, AAZV executive director, and Adine Nicholson, Julie Fazlollah, and Pam Brownlee for their support in making this year’s conference a success. Finally, welcome to Orlando – we hope you have a wonderful time at the conference advancing your education and spending time among friends!! And don’t forget to take a moment to embrace your inner child and enjoy the magic of Disney!! We hope you return home excited about the future of our profession and the difference we can make for animal health and conservation. Warm wishes, Michael Adkesson, DVM, Dipl.
