9 DEDICATORIA AL DR. CARLOS SANCHEZ WIDMANN Nació el 27 de octubre de 1936, en la ciudad de México D.F. Estudio en la Escuela Nacional de Medicina Veterinaria, Universidad Nacional Autónoma de México, siendo la segunda generación de Ciudad Universitaria ( ). Teniendo como compañeros al Dr. Alejandro Cuadra, Dr. Fabián Ubiña, Dr. Enrique Salinas Aguilera entre otros. Su interés por las aves se remonta a antes de entrar a a la facultad de Medicina Veterinaria, ya que por los años 50 s, su tío fue avicultor de gallina de postura con 18,000 aves y algo de pollo de engorda, pero desgraciadamente en esa época apareció una de las enfermedades que mas estragos ha causado en México como es el Newcastle y los obligó a retirarse del negoció avícola. El Dr. Sánchez Widmann inició su propio negocio en el año de 1962 con 20, 000 pollos de engorda en la zona de Chimalhuacan y al mismo tiempo fue asesor técnico externo de la empresa Alimentos Industriales (AISA) de 1959 a Posteriormente, de 1962 a 1964 fue asesor de Alimentos Malta, para luego regresar a AISA hasta el año de También en esa década fue asesor de Laboratorios Vinelad trabajando junto con el Dr. Alejandro Cuadra y el Dr. Miguel Angel Marquez. Para los años 70 s, se asocia con el Dr. José Garcia para engorda de pollo durante dos años. Posteriormente en los 80 s también se asocia con el Sr. Juan Antonio Sánchez Barse con una producción de 90,000 pollos de engorda y con el Sr. Arturo Gilio con 60,000 pollos de engorda en la zona de Zumpango, Estado de México. Y es justo durante esa década cuando el Lic. Raúl Canales lo induce a unirse a la Asociación de Avicultores del Valle de México, ocupando el cargo de Presidente de Consejo en el período de 1982 a 1986, y según lo permiten los estatutos, toma cargo de Secretario General del Consejo en la Unión Nacional de Avicultores (UNA) de 1983 a En 1988, se asocia con el Sr. Alfonso Larey para la producción de 450,000 pollos de engorda en la zona del Lago de Guadalupe, terminando en 1996, debido a dos causas: por un lado la crisis de la devaluación de la moneda en México, y por otro la crisis de la escasez del grano. Pero permanece en la UNA como Gerente General, puesto que ocupa a la fecha, en donde su principal función es el enlace de aspectos técnicos, sanitarios y productivos con la SAGARPA y en la Secretaria de Asistencia participa en la elaboración de normas relacionadas con la actividad avícola. Actualmente también es miembro del Comité Nacional de Sanidad Animal (CONASA), enfermedades de las aves, desde Así mismo ha participado dentro de algunos consejos de ANECA, siendo Vocal o miembro del Comité Científico.
10 Dentro del área de asesorías, ha participado con varias empresas avícolas, entre ellas: Agropecuaria El Avión (actualmente) Avícola Nochistongo Avícola Simón Bolivar Propollo Alcer Actualmente continua participando en la avicultura con 200,000 pollos de engorda en la zona de Texcoco, Estado de México. A lo largo de su trayectoria, al Dr. Sánchez Widmann le ha tocado ver y participar en los procesos de consolidación y crecimiento de la industria avícola desde sus inicios, y actualmente en la concentración de la misma. Sin duda alguna el Dr. Carlos Sánchez Widmann, ha sido un ejemplo para las nuevas generaciones de Médicos Veterinarios, ya que mas allá de cuidar la salud de las aves, ha demostrado que los Médicos Veterinarios tenemos la capacidad de encabezar puestos tanto políticos, como administrativos, e incluso empresariales. FELICIDADES DR. CARLOS SÁNCHEZ WIDMANN
11 DEDICATION OF THE XXVII ANECA CONVENTION TO DR. CARLOS SANCHEZ WIDMANN Dr. Carlos Sanchez Widmann was born October 27, 1936 in Mexico City D. F. He studied at the National School of Veterinary Medicine, Autonomous National University of Mexico, where he was in the 2 nd generation from 1956 to His associates were Dr. Alejandro Cuadra, Dr. Fabián Ubiña, Dr. Enrique Salinas Aguilera, among others. His interest in poultry dates back before entering Veterinary School. In the 50 s he worked with his uncle as a poultry producer of 18,000 hens. Unfortunately during that time one of the awful illnesses appeared in Mexico: Newcastle Disease. This forced them to retire from the poultry business. In 1962 Dr. Sanchez Widmann began his own business in Chimalhuacan with 20,000 chickens. He served as external technical advisor for the AISA Company from 1959 to Then from 1962 to 1964 he was technical advisor for Malta, afterward returning to AISA until Also during that decade he acted as technical advisor for Vineland Laboratories, working together with Dr. Alejandro Cuadra and Dr. Miguel Angel Marquez. During the 70 s he partnered with Dr. José Garcia to raise chickens for two years; then later on in the 80 s he associated with Mr. Juan Antonio Sanchez Barse, producing 90,000 chickens; and with Mr. Arturo Gilio producing 60,000 chickens in the Zumpango, State of Mexico area. It was during the 80 s, that the Layer Raul Canales induced him to join the Association of the Valley of Mexico, occupying the president's advisory position from 1982 to 1986; and according to what the statutes allowed, he took the general secretary's advisory position in the National Union of Poultry Producers (UNA) from 1983 to In 1988 he worked with Mr. Alfonso Larrey producing 450,000 chickens in the area of Guadalupe Lake, State of Mexico. They had to quit raising chickens in 1996 due to two causes: 1) the crisis of the devaluation in Mexico and 2) a grain shortage crisis. However, he continued on as General Manager of National Union of Poultry Producers (UNA), which position he presently holds, where his main function is in the connection of technical aspects, sanitariums, and production with the Mexican Authorities (SAGARPA), and as Attendance Secretary he participates in the elaboration of norms related to poultry activity. From 1990 to the present he has also been a member of the National Committee of Animal Health (CONASA), Diseases of Poultry. Likewise, he has participated in various advisory positions of ANECA as well as serving as a member, Vocal, and as a member of the scientific committee.
12 Within the area of advisory, he has participated with several poultry companies, among them: Agropecuaria El Avion (at the moment) Avícola Nochistongo Avícola Simón Bolívar Productora de Propollo Avicola Alcer He currently continues to be an active poultry producer, raising 200,000 chickens in the Texcoco area. During his career Dr. Carlos Sanchez Widmann has played an integral role in the consolidation and growth of the poultry industry from its beginnings. He continues to do the same. Undoubtedly Dr. Carlos Sanchez Widmann has been an example for the new generations of veterinarians now finding themselves with the responsibility of caring for poultry health. He has demonstrated that veterinarians have the capacity to head influential political, administrative, and even managerial positions. Congratulations!!!!!! Dr. Carlos Sanchez Widmann.
13 DEDICATION OF THE ANECA/WPDC JOINT MEETING TO DR. HIRAM LASHER The joint meeting of the XXVII Convención Anual ANECA and the 51 st Western Poultry Disease Conference is proudly dedicated to Dr. Hiram Lasher for his many contributions to the poultry industry in Mexico, the USA and throughout the world. Dr. Lasher obtained his DVM from Cornell University in 1942 and began providing routine diagnostic service to independent poultry farms in the Eastern and Central New York area. He then took a position as an extension veterinarian in Delaware with the State Board of Agriculture focusing on poultry pathology and disease control. In 1950, Dr. Lasher established the Delaware Poultry Laboratories, which specialized in poultry diagnostics and production of poultry vaccines. This business eventually became Sterwin Laboratories from which Dr. Lasher retired in Subsequently, he established a new company, Intercontinental Biologics in Millsboro, Delaware. This company was subsequently acquired and renamed Intervet America, Inc. Some of Dr. Lasher s accomplishments include the production of the first vaccines for use against tenosynovitis and infectious bursal disease, the first commercial production of vaccines using JMK and Holland strains of infectious bronchitis virus, and the first tissue-culture fowl pox vaccine. Dr. Lasher is still actively consulting throughout the world as President of Lasher Associates, Inc. Dr. Lasher is a strong supporter of new students and researchers in the field of avian medicine. He and his brother, the late William Lasher of Sunrise Farms, have been long-time contributors to the Western Poultry Disease Conference and the annual conferences of ANECA, and were the first Benefactor contributors to WPDC. Dr. Lasher has been honored with numerous awards and is past recipient of the American Association of Avian Pathologists C. A. Bottorff Award, an award that he helped establish and fund. Additionally, Dr. Lasher has received well-deserved recognition for his public service to the Delmarva Poultry Industry and to the State of Delaware, its people and government.
