He received his master’s degree at the University of Georgia besides reactivating his US accredited veterinary licensure. He also took additional courses in avian medicine at North Carolina State University. Dr. Cervantes is a member and Diplomate of the renowned American College of Poultry Veterinarians, and served as its president. Hector also served as president of the American Association of Avian Pathologists (AAAP), being the first AAAP president from a Spanish-speaking country. Besides being Senior Manager of Poultry Veterinary Services at Phibro Animal Health, Dr. Cervantes is also an adjunct professor of avian medicine in both the School of Veterinary Medicine at the University of Georgia and School of Veterinary Medicine at North Carolina State University.

Dr. Cervantes has received numerous awards in the US and Latin America; has given some 135 presentations as an invited speaker in the US, Latin America, and other parts of the world; and has given more than 80 online presentations. His greatest contribution has been the development of the “Cervantes Method” of objectively and uniformly evaluating the quality of newly hatched chicks, integrating the most important physical and microbiological parameters. This method has been adopted by the majority of Latin American poultry enterprises. iii iv 68th WPDC SPECIAL RECOGNITION AWARD GREGG J. CUTLER Dr. Gregg Cutler was born in Los Angeles, CA. His grandparents settled in LA after emigrating from Eastern Europe in about 1911. His paternal grandfather established an egg distribution business called Covina Egg Farms. He traveled to small producers then sold the eggs to restaurants and small grocery stores. As a small child, Gregg remembers going with his grandfather or father or uncle to pick up eggs. Gregg also remembers being fascinated by the chickens - especially the dead ones. As the San Fernando Valley had become too developed for chicken farms, the operation was moved to Moorpark and the brothers entered into an agreement with S&K in Moorpark. After a few years, Julius Milling started to expand into what became Julius Goldman’s Egg City. Gregg’s father, Bernard, worked at Egg City, where he handled all sales and marketing until his retirement. As he studied a UC Santa Barbara and Ventura College, Dr. Cutler changed his mind about a major. Originally, he was going to study marine biology. While working at a summer camp, he met a girl named Jody who wanted to become a veterinarian. She was a zoology major at UC Davis. That occupation sounded like a good idea so he tried it out by working in a mixed practice after school and weekends. After Ventura College, Gregg transferred to UC Davis as a zoology major. The girl never made it to veterinary school but became his wife of nearly 50 years. After receiving his AB in zoology, Gregg went to graduate school in avian nutrition as a graduate student of Dr. Fred Hill. During that time he also worked in the avian physiology lab of Dr. Ray Berger. At the end of that first year in graduate school, he was admitted to veterinary school at UC Davis. After Dr. Cutler graduated from veterinary school, he practiced for over a year in the mixed practice he had worked for as an undergraduate. They treated anything non-human that walked, crawled, swam, slithered, or flew. After a little more than a year, Dr. Cutler received a call from Dr. Henry Adler. There was going to be a residency in poultry at Davis - was he interested? He couldn’t say yes fast enough. Because Jody had a great job and they had just bought a house, Dr. Cutler commuted every week to Davis for almost two years. Dr. Dick McCapes supervised his residency. He worked closely with Drs. Art Bickford and Yan Ghazikhanian, and shared an office with Dr. Ray Bankowski. The field time introduced him to the Northern California Poultry Industry. By 1977, Dr. Cutler had completed a residency and a MPVM. After the completion of his time in Davis, Dr. Cutler went to work at Egg City as a staff veterinarian. Working with Dr. John Allen, he was responsible for bird health and care in addition to food safety of processed egg product. The lab made some of their own vaccines and did most of their own diagnostic testing. Dr. Cutler left Egg City in 1980 and worked as the Western Regional Veterinarian for DeKalb Ag Research. He provided technical service, customer training and supervised the vaccine manufacturing plant. During that time he met most of the Southern and Central California producers. In 1983-84, Dr. Cutler was president of WPDC. By 1985, Egg City had undergone several ownership changes. Dr Allen had died and the ranch needed a veterinarian and an experienced manager. Dr. Cutler became Executive Vice President/ COO. He was responsible for v all operations of the 3.5 million bird integrated egg producer, two million per year hatchery and rearing, five hundred ton-per-day feed mill and egg processing and breaking plants. In 1988, Dr. Cutler founded his consulting practice for poultry medicine, Cutler Associates International. The four veterinarians are involved with poultry health, management, food safety, and animal welfare for their many clients. During this time, Dr. Cutler became a Diplomate of the American College of Poultry Veterinarians and in 1996-97 served as president of AAAP. In addition to his practice, Dr. Cutler has served on the American Veterinary Medical Animal Welfare and Legislative Committees and currently serves in the House of Delegates. He also continues to serve on the California Animal Health and Food Safety Board, which he has since its inception in 1986. In his spare time, Gregg and his wife restore and drive antique carriages. They also officiate in carriage driving shows all over the United States. Not long ago, Dr. Cutler fulfilled a lifelong dream to become a private pilot. He has earned his license and is working on an instrument rating. The UC Davis School of Veterinary Medicine recently awarded Dr. Cutler the Alumni Achievement Award for his recognized leadership and dedicated service to protecting the health and safety of poultry in California, the United States, and internationally. We are extremely proud to present the 68th Western Poultry Disease Conference Special Recognition Award to Dr. Gregg J. Cutler. We wish him well in his continued dedicated involvement in the poultry industry, community, and family. vi IN MEMORIUM CRAIGMYLE RIDDELL October 19, 1933 – November 18, 2018 Born and raised in Scotland, Craig first attended St. Andrew’s University graduating with a BSc in General Science in 1954. He and his wife, Pat, then immigrated to Canada where he later completed his DVM (honors) at the Ontario Veterinary College in Guelph, Ontario. After graduation, he worked as a large animal practitioner in Alberta, then relocated to Ontario where he worked as a diagnostic pathologist and a veterinarian at a poultry breeding company. He continued his education completing a MSc in Veterinary Pathology at the University of Connecticut in 1967 and PhD at the Western College of Veterinary Medicine (WCVM), University of Saskatchewan in 1975. During his PhD studies at the WCVM, Craig was recruited as an assistant professor in the Department of Veterinary Pathology in the same institution, and received tenure in 1977. Along with teaching both agriculture and veterinary medicine undergraduate and graduate students, he was actively involved in the WCVM, volunteering his time and expertise to various committees including strategic planning, college review, audio visual, research task force, animal resources, admissions, awards, library, tenure, student-faculty, and electron microscopy. He also served on the University Committee on Animal Care and Supply. Even after his retirement, Dr. Riddell regularly visited the department to converse with old colleagues and former students and attended noon hour seminars presented by current research and diagnostic pathology students. Not only dedicating his time to the WCVM, Dr. Riddell was also a founding member of the Saskatchewan Poultry Extension Program in 1978 – a program first of its kind and to this day the only of its kind in Canada. This program, initially funded by the Saskatchewan government, was a two-year trial period monitoring flock performance, identifying problem areas, extension and field work to alleviate problems. The trial period was a success, and after 41 years the now-industry funded program is still in operation. In addition to his teaching, college and extension services, research was an important aspect of his career, mainly poultry diseases with special reference to leg weakness and nutritional pathology. Publishing over 96 peer-reviewed papers, he received the Research Paper Award for best research paper in Avian Diseases (1976) and the PP Levine Award for Best Paper Published in Avian Diseases (1984). He authored a handbook on Avian Histopathology while on sabbatical at the University of Georgia, conducted research on poultry vaccination, bone and liver diseases at the Houghton Poultry Research Station, England and the Victorian Institute of Animal Science, Victoria, Australia, and worked at the diagnostic laboratory in San Bernardino, California during the course of his other sabbatical leaves. Sharing his research and knowledge was important to Dr. Riddell. He was on the American Association of Avian Pathologists editorial boards, as well as other associations such as the Saskatchewan Poultry Industry Council, Western Meeting of Poultry Clinicians and Pathologists, Western Conference of Veterinary Diagnostic Pathologists, and Non-Ruminant Committee of Farming for the Future. He was a large contributor to the Western Poultry Disease Conference, serving as proceedings editor, program chair and president, as well as contributing oral presentations. Craig and Pat kept busy with their two daughters, Morag and Cara, coaching their soccer teams, teaching them to ski, Pony Club, or recitals. Later, he welcomed a grandson, Keiran. He loved the outdoors, skiing, camping and hiking, so much that he hiked the Continental Divide in Alberta and the British Isles. Outdoor trips were enjoyed by all who joined him, being an avid geologist, he was always keen to point out interesting facts about the landscape. After retirement, he served as councillor for the Rural Municipality of Corman Park and trained border collies to work with sheep. Being a true Scotsman, he loved loud bagpipes. Craig left an enormous legacy and will be missed by all who knew him. vii viii ASOCIACIÓN NATIONAL DE ESPECIALISTAS EN CIENCIAS AVÍCOLAS MESA DIRECTIVA GESTIÓN 2018-2020 COMITÉS DE APOYO 2018-2020 PRESIDENTE RICARDO CUETOS COLLADO COMITÉ TÉCNICO ARMANDO MIRANDÉ JUAN CARLOS VALLADARES DE LA CRUZ ASSAD HENEIDI ZECKUA VICEPRESIDENTE ASSAD HENEIDI ZECKUA VOCALES ROBERTO SEÑAS CUESTA OTILIO ORTIZ ODETTE URQUIZA RELACIONES COMERCIALES LUIS ARTURO SUAZO OROZCO RELACIONES CON ASOCIACIONES LUIS ARTURO SUAZO OROZCO TESORERÍA MARITZA TAMAYO MARCO REBOLLO RELACIONES INTERNACIONALES HÉCTOR CERVANTES SECRETARIA DIANA RUIZ COMITÉ DE MEMBRESIAS ALMA SELENE VAZQUEZ DELGADO JORGE MIGUEL IRIARTE GERENTE ADMINISTRATIVO JULIO ARELLANO RODRIGUEZ COORDINADOR DE EXPRESIDENTES MIGUEL ANGEL CASILLAS COORDINADORES DE ESTATUTOS BERNARDO LOZANO ix LISTA DE PATROCINADORES DE ANECA • SANFER • BM EDITORES • PHIBRO • ASESORIA & DIAGNOSTICO • CEVA • HIPRA MEXICO • LUBING • SISTEMAS AGROPECUARIOS JAT • BIOMIN • PISA AGROPECUARIA • ECO ANIMAL HEALTH • LABORATORIO AVI-MEX • LABORATORIOS AVILAB • BAYER • PLASSON • ADYFARM • ANGLOCORP • ZINPRO • ARM & HAMMER ANIMAL AND • IDEXX FOOD PRODUCTION • LABORATORIO KARIZOO • BOEHRINGER • DIAMOND V • DSM • VETANCO • ATISA • COBB • MSD • EW NUTRITION DE MEXICO x 68th WPDC CONTRIBUTORS LIST (As of March 21, 2019) SUPER SPONSORS CEVA Animal Health Lenexa, KS BENEFACTORS American Association of Avian Pathologists Jacksonville, FL Zoetis Durham, NC PATRONS Asociación Nacional de Especialistas en Ciencias Avícolas México, D.
