Proceedings of the 60Th WPDC Is a 5-Year Compilation, Containing Proceedings from the 56Th Through the 60Th WPDC PROCEEDINGS OF THE SIXTIETH WESTERN POULTRY DISEASE CONFERENCE March 20-23, 2011 Sacramento, CA ©2011 Western Poultry Disease Conference ii SPECIAL ACKNOWLEDGMENTS The 60th 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 40 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. The WPDC is extremely honored to give a special acknowledgement to Pfizer Poultry Health who contributed at the Super Sponsors level by sponsoring our electronic proceedings. In addition, WPDC is pleased to acknowledge our Benefactor contributors, American Association of Avian Pathologists, Inc., Intervet/ Schering- Plough Animal Health and Merial Inc. Once again, the WPDC is forever grateful to our distinguished Patrons, Donors, Sustaining Members, and Friends of the Conference who are just as important 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 the WPDC. Dr. Larry Allen, Program Chair for the 60th WPDC, would especially like to thank all those who submitted titles for their contributions to the success of this year’s conference. Without their substantial efforts the Conference could never come to fruition. I extend sincere thanks also to all the presenters while we worked together to organize the program. Some presenters originally requested poster presentations and were willing to change to an oral presentation of their paper, or vice versa. This flexibility on the presenters’ part helped keep us within time and space constraints of the program and the poster viewing room. Many thanks to my colleagues on the WPDC Executive Committee for their kind assistance and advice during the preparation of this program. Thanks also to the moderators who graciously accepted the opportunity to serve the Conference and keep the sessions orderly and on time. Finally, I gratefully acknowledge the assistance of the Staff at UCD Conference Events and Visitors Services for registering and assisting our guests and making the conference come together. Thank you again, one and all who made this milestone 60th WPDC a reality. Many have provided special services that contribute to the continued success of this conference. For this year’s meeting, the WPDC has contracted Conference Events & Visitor Services, of the University of California, Davis, for providing budgetary support for the conference. We would like to thank Ms. Stephanie Horgan and Ms. Teresa Brown for their work with our conference. We thank Dr. David Frame for editing and producing another outstanding Proceedings of this meeting. Dr. Frame is indebted to Ms. Sherry Nielson for her tireless dedication in proofreading and formatting the Proceedings for publication. We express our gratitude to all authors who submitted manuscripts. A special thanks goes to Pfizer Poultry Health for their monetary sponsoring of the flash drives for this year’s meeting. We again acknowledge and thank Ominpress (Madison, WI) for the handling and printing of this year’s Proceedings and for electronic reproduction of the meeting proceedings on flash drives.

There were 24 people in attendance. APPROVAL OF 58th WPDC BUSINESS MEETING MINUTES The minutes from the 58th WPDC business meeting were reviewed and a motion was carried to approve them as printed in the Proceedings of the 59th WPDC. ANNOUNCEMENTS Dr. Chin acknowledged all the contributors; in particular, those contributing at the Benefactor level, which included the American Association of Avian Pathologists, Intervet/Schering-Plough Animal Health and Pfizer Poultry Health. He also thanked all the contributors for their generous donations. The efforts of the current WPDC officers were acknowledged for their work and participation in the organization of this year’s meeting. Dr. Chin asked that we remember Dr. Charles Whiteman and Mr. Lloyd Merrill (Merrill’s Poultry Farm, Paul, ID), who passed away the past year. REPORT OF THE SECRETARY-TREASURER Dr. R. Chin presented the Secretary-Treasurer report. First, he discussed the budget for the 57th WPDC in Mexico. Previously, he did not report all the expenses to ANECA for the budget. There was a net gain of $49,402.02 which ANECA agreed to distribute equally with WPDC. Hence, there was an overall gain of $24,701.01 for WPDC. Since ANECA raised more than three times the amount in sponsor/exhibitors contribution, the WPDC Executive Committee agreed to ask ANECA if, rather than give a lump payment to WPDC, that they would contribute at least US$1000 each year to WPDC. ANECA agreed to do so. Dr. Chin then discussed the budget for the 58th WPDC. There were only 184 registrants – a 10% decrease from the expected 200 registrants. There was $24,050 in contributions with a total income of $59,525. Total expenses were $72,562.85, for a net loss of -$13,037.85. The current balance in the WPDC account was $61,600.85.

  • Staphylococcus Aureus, a Gram-Positive Coccus Occurring in Clusters (Grapes Like)
    STAPHYLOCOCCOSIS, STREPTOCOCCOSIS & CAMPYLOBACTERIOSIS DEFINITION Staphylococcosis is acute systemic or chronic disease of birds characterized most frequently by purulent arthritis and tenosynovitis. OCCURRENCE • Staphylococcal infections of poultry occur worldwide and affect all classes of birds. • Outbreaks are most important in turkeys and broilers. • The organisms are common in the environment and are especially associated with the skin (normal inhabitant). • Most diseases produced by Staphylococcus sp. are associated with ahistory of break in the skin or beak (trauma, beak trimming, toe trimming, foot pad burns etc.). OCCURRENCE • Avian infections tend to be caused by types occurring in birds rather than human strains. • Isolates pathogenic for one class of poultry are usually pathogenic for other classes of birds. • Toxigenic strains capable of causing food poisoning can contaminate the skin of processed poultry (zoonotic importance). • The source of these strains at present is in debate. • Bio-typing indicates processing plant worker origin while plasmid profile indicates poultry origin. HISTORICAL INFORMATION • Staphylococci were first discovered to be a cause of arthritis in geese in 1892. • Since that time they have been identified as the cause of a variety of localized and systemic diseases in many different avian species and in most areas of the world. • The disease was more common in turkeys when they were raised on range than it is now. ETIOLOGY • 1. Most staphylococci isolates have been identified as Staphylococcus aureus, a Gram-positive coccus occurring in clusters (grapes like). Pathogenic isolates are usually coagulase positive. 2. Organisms are moderately resistant to common disinfectants. • Chlorine-containing disinfectants are efficacious in the absence of organic material.

MICHIGAN STATE UNIVERSITY Robert Carey Hargreaves 'I 965 THESIS LIBRARY Michigan State University ABSTRACT THE EFFECT OF DEGREE 0F DEBEAKING.AND CAGE POPULATION SIZE ON SELECTED PRODUCTION CHARACTERISTICS OF CAGED LAYERS by Robert Carey Hargreaves Debeaking is commercially used as one method of preventing canni- balism in young growing chickens, laying hens, turkeys, and game birds. In recent years, the relative severity of debeaking has increased. The primary purpose of this experiment was to determine the effects that severe degrees of debeaking might have on production characteristics of caged laying chickens. Single Comb'White Leghorn pullets were debeaked at 18 weeks of age and placed in l-bird and 3-bird cages. Other birds from the same stock were debeaked at 24 and 25 weeks of age and placed in 2-bird cages and 21-bird cages. Three degrees of debeaking were used -- 1/2, 3/& and all of the distance between the tip of the beak and the nostrils. Ap- proximately the same amount of both upper and lower mandibles was re- moved. Non-debeaked birds served as the controls. The birds with all of the beak removed are referred to as "entirely debeaked”. Compared with birds in any of the other three treatments, entirely debeaked birds gave poorer results. They took longer coming into egg production, laid fewer eggs, ate less feed and made smaller body weight gains. All of these differences were highly significant.

  • Commercial Egg Tip
    The University of Georgia Cooperative Extension Service College of Agricultural and Environmental Sciences / Athens, Georgia 30602-4356 NOVEMBER 2010 COMMERCIAL EGG TIP . A BRIEF LOOK AT DIFFERENT HOUSING SYSTEMS FOR COMMERCIAL LAYERS Concerns for laying hens’ welfare began in the 1960’s and led to an aversion to eggs produced by hens housed in conventional battery cages. As a result the European Union (EU) has banned the use of battery cages beginning in January 2012. This move has resulted in the development of alternative housing systems for laying hens. While the EU ban does not currently apply to the commercial egg producers in the United States, some states have made moves towards banning the use of battery cages for laying hens, the most recent being California. With the passing of Proposition 2 in California there has been a renewed effort to develop alternative housing systems to meet all the requirements of good hen welfare. A number of different systems are currently being used to house laying hens, but the majority of laying hens in the US are still housed in conventional cages. Each of the systems used have advantages and disadvantages that vary based on location, management, and genetic strain of the hens. Conventional Cage Housing System Conventional battery cages for laying hens were first developed in the US during the 1920s to 1930s. The system was developed to reduce the incidence of disease and parasites and also to reduce cannibalistic pecking. Cages makes management of the birds easier and requires less space than the other systems. No bedding material is used in this system as the cages are suspended above the floor allowing the bird droppings to fall through the mesh floors and collect below the cages.

  • 1 Review on Avian Encephalomyelitis
    Review on avian encephalomyelitis Tsehaye Neges1 and Haftey Sahle2 1DVM, Area Sales Manager (ASM) at Ethiochicken, Tigray, Ethiopia 2DVM, field Practitioner at Tanqua abergele, Tigray, Ethiopia [email protected] Abstract: Summary: This paper is mainly aimed to review the avian encephalomyelitis. Avian Encephalomyelitis (AE) is an economic concern to poultry industry as it causes economic loss by declining egg production in laying hens as well as egg hatchability . This disease is very common in commercial aviculture which is caused by genus Tremovirus, family of Picornavirridae. It is essentially an enteric infection which can be acquired horizontally between birds by oral ingestion and vertically from infected breeding females through the egg to progeny. It affects mainly young chicken and it is characterized by neurological signs like ataxia and rapid tremors of the head and neck giving rise to the former name of ‘‘Epidemic Tremor ” but no gross lesions are seen in the brain of birds. Both morbidity and mortality can be 50% sometimes reach up to 60% and Its Vertical infection followed by horizontal infection causes a characteristic biphasic mortality pattern. Protection against this virus can be successfully achieved by using the appropriate vaccine strains. Vaccinated birds are life time immune and recovered do not spread the virus. Wild birds are not considered as reservoir of the virus which poses no threat to the human and this disease is not considered as zoonotic disease. Therefore it can be concluded that AE is economically important viral disease which can hinders the poultry production, so it is recommended to control the disease by proper vaccination of parent stock.

  • NATURAL BEAK SMOOTHING Smoothing, Saving, Performing
    NATURAL BEAK SMOOTHING Smoothing, saving, performing FOR BROILERS BREEDERS FEEDING Developed in cooperation with the major breeding companies NATURAL BEAK SMOOTHING, A SUSTAINABLE SOLUTION FOR POULTRY FARMERS “ GERMANY Markus Böckermann looked for a sustainable solution because of the ban of beak trimming in Germany. “The results of the test phase were impressive. After 11 weeks, there was no longer any difference in shape between the infrared trimmed beaks and the beaks subjected to Natural Beak Smoothing.“ “ INDIA Life Line Feeds is a pioneer in the Indian poultry market. So the company was eager to test the Natural Beak Smoothing solution as an alternative to mechanical hot blade debeaking. The solution fits perfectly with the philosophy of Life Line Feeds’ Managing Director: for Mr. Kishore Kumar, animal welfare is a top priority. According to him, Natural Beak Smoothing has proven to drastically reduce stress and risk of infections in his broiler breeder houses. “ BELGIUM Dirk Mertens finds it important to invest in systems that improve animal welfare. “I notice there is less mortality among our chicks, because they don’t suffer a relapse. They have less stress and can just continue eating during the first days. We also notice a greater uniformity among the chicks. All these things eventually lead to a better end result.” BEAK TREATMENT » SOLUTIONS TODAY WHY BEAK TREATMENT = A PREVENTIVE MEASURE EFFECT OF BEAK TREATMENT: / to have optimal performance of flock laborious and time consuming Infrared beak trimming in hatchery 01 / to
