PROCEEDINGS OF THE SIXTY-SEVENTH WESTERN POULTRY DISEASE CONFERENCE April 16-18, 2018 Salt Lake City, UT PROCEEDINGS OF THE SIXTY-SEVENTH WESTERN POULTRY DISEASE CONFERENCE April 16-18, 2018 Salt Lake City, UT ©2018 Western Poultry Disease Conference Western Poultry Disease Conference Special Recognition Award David D. Frame, DVM, DACPV The 67th WPDC is honored to present the WPDC Special Recognition Award to Dr. David D. Frame. Dr. David Frame was born (in July 1955) and raised in Kearns, Utah. As a youth, Dave developed an interest in birds. Along with his dad, he designed an extensive breeding and growing program for exhibition chickens. Dave continues to be involved with judging of these birds at various county and state fairs. David graduated from Utah State University (USU) in 1980 with a B.S. in Animal Science. He was then accepted into the second class of veterinary students at Oregon State University (OSU). At that time, vet students had to spend over a year at Washington State University in Pullman, WA, to receive the necessary training in small animal medicine and surgery. In 1984, Dave received his Doctor of Veterinary Medicine (DVM) degree from Oregon State University, and subsequently, completed the 2-year residency program in avian medicine at the University of California, Davis. Dave is grateful to be able to spend time with Dr. Art Bickford while based in the Turlock laboratory, as one of his current roles is Avian Veterinarian at USU’s Central Utah Veterinary Diagnostic Laboratory. Upon completion of his residency, Dave moved back to Utah and began his career as the Chief Veterinarian for Moroni Feed Company. For 12 years, he was responsible for all turkey health programs and disease diagnostics, for both breeder and meat turkeys, at Moroni Feed Company. In 1998, David accepted the position of Extension Poultry Specialist for USU. In this role, he supports and educates small flock and backyard poultry owners, game bird producers, and commercial turkey and chicken growers in poultry health and management. Additionally, he is an associate professor in the USU department of Animal, Dairy, and Veterinary Sciences, and actively participates in providing community education classes in backyard poultry raising. And, for his third and final role, Dr. Frame serves as the Avian Veterinarian in USU’s Central Utah Veterinary Diagnostic Laboratory. David’s contribution and service to the industry has not gone unrecognized. He was awarded a Service Appreciation award for 3 consecutive years (2004-2006), and was recently honored as “Scientist Of The Year” in 2016, by the Pacific Egg & Poultry Association. David has participated in the Western Poultry Disease Conference since 1985. Of course, his most memorable and “earth-shaking” WPDC meeting was in 1986 in Puerto Vallarta!?! In 2000, Dave accepted the position of WPDC’s Proceedings Editor, and has since provided 18 years of outstanding service. He continued to improve the quality of the proceedings and to maintain it as one of the most referenced publication of meetings specializing in poultry medicine. He has led the digitization of the proceedings from print to CDs, to flash drives, and finally, to web- based publication. David and Lisa met at USU and were married in 1979. They have four children and love spending time with their four grandchildren. David spent his mission in Honduras and Nicaragua, where he became fluent in Spanish and learned to love hot and spicy food! David enjoys hiking in southern Utah, geology, bird watching and identifying bird calls. He enjoys gardening and has been breeding his own line of Indian corn for many decades. Every Halloween, neighbors come to see David’s front porch, which he turns into an elaborate seasonal display that he redesigns every year. And of course, there are the SF Giants. The 67th WPDC is honored to recognize Dr. David D. Frame for his service and advancement of knowledge of avian diseases in the western region, and for his 18 years, and counting, as Proceedings Editor for the WPDC. 67th WPDC CONTRIBUTORS LIST (As of April 5, 2018) SUPER SPONSORS CEVA Animal Health Lenexa, KS BENEFACTORS American Association of Avian Pathologists Jacksonville, FL Zoetis Madison, NJ PATRONS Alltech Cobb Vantress Lexington, KY Siloam Springs, AR Asociación Nacional de Especialistas Elanco Animal Health en Ciencias Avícolas Greenfield, IN México, D.

Frame, DVM Moroni, UT Ephraim, UT iv SPECIAL ACKNOWLEDGEMENTS The 67th Western Poultry Disease Conference (WPDC) is honored to acknowledge the many contributions and support to the Conference. The financial contributions provide support for outstanding presentations and to help pay for some of the costs of the Conference, thus helping us to maintain a relatively low registration fee for an international conference. More than 30 organizations, companies and individuals have once again given substantial financial support. Many companies and organizations, including some that also contribute financially, send speakers at no expense to the Conference. We thank all these people, and acknowledge their support and contribution. Once again, the WPDC is forever grateful to our distinguished contributors and supporters of the conference who are vital in making the conference a success. All our contributors and supporters are listed on the following pages. We greatly appreciate their generosity and sincerely thank them and their representatives for supporting this year’s meeting of WPDC. Dr. Rodrigo Gallardo, Program Chair of the 67th WPDC, would like to thank the School of Veterinary Medicine at UC Davis, for the support and trust given as the head of the Poultry Medicine Program. His team at the Poultry Medicine Laboratory Ana Paula da Silva, Alejandra Figueroa, and Sofia Egana for administrative and technical help. Most importantly to his family his wife Gigi and two kids Matias and Emma for supporting him at all times. Many have provided special services that contribute to the continued success of this conference. For this year’s meeting, the WPDC has contracted Conference and Events Services, of the University of California, Davis, for providing budgetary and registration support for the conference. We would like to thank Ms. Teresa Alameda, Ms. Lina Layiktez, and the staff at Conference & Event Services for their exceptional work with our conference. Again, we thank Ms. Elvie Martins, the California Animal Health & Food Safety Laboratory System, Bob and Janece Bevans-Kerr and AAAP for their continual support. For the past 21 years, Dr. Chin served as secretary-treasurer of the WPDC. He has decided it is time to hand it over to the younger folks, so, this was his last year as secretary-treasurer. There are so many people he wants to thank for their support, including all the contributors, sponsors, presenters, administrative staff and attendees. These folks are the ones who are truly responsible for the continual growth and success of the WPDC. Rich would like to acknowledge and thank Art Bickford, Dick Yamamoto, and Rosy for their unwavering support, guidance, and “convincing” him to serve as secretary-treasurer. Rich is extremely grateful to Dave Frame who was equally responsible for the success of WPDC. Finally, Rich would like to thank his wife, Elaine, for allowing him to spend the numerous hours working on the WPDC, especially talking with Rosy on the phone! Yes dear, now it’s time for that “honey-do” list… We thank Dr. David Frame for editing and producing another outstanding Proceedings of this meeting. Dr. Frame is indebted to Mr. Dana Frame for his meticulous proofreading and formatting the Proceedings for publication. We express our gratitude to all authors who submitted manuscripts, and are especially appreciative of those who submitted their manuscripts on time. Once again, we acknowledge Bruce Patrick (Graphic Communications, Brigham Young University) for the front page cover design displayed in the electronic proceedings. v 67th WESTERN POULTRY DISEASE CONFERENCE OFFICERS PRESIDENT PROGRAM CHAIR-ELECT Dr. Gabriel Sentíes-Cué Dr. Sarah Mize TVMDL, Center Laboratory California Department of Food & Agriculture Texas A&M University System [email protected] [email protected] MEETING SUPPORT CHAIR PAST PRESIDENT Dr. Yan Ghazikhanian Dr. Susantha Gomis Western
