Program - ADSA-ASAS Joint Meetings
Welcome Letter Welcome to the First Joint Meeting of ADSA, ASAS, and AMPA Dave Beede ADSA President Jim Lauderdale ASAS President Assefaw Tewolde AMPA President Welcome to the first joint meeting of the American Society of Animal Science and the American Dairy Science Association with the Mexican Association of Animal Production (AMPA). We hope the venue provides optimal opportunities for professional networking and scientific information exchange on leading edge research in animal agriculture and animal food products. We particularly hope you will take this unique opportunity to renew acquaintances and develop new relationships with our Mexican colleagues. AMPA will be meeting June 22-23 and will be joining ADSA and ASAS for the remainder of the meeting ending at noon on June 26. New Poster Format: Each day will start with a 2-hour block of time for poster display (7:30 to 9:30 AM). Neither symposia nor oral sessions will be scheduled during this time slot. Plan your morning coffee with colleagues discussing the latest research in your specialty area. Let us know what you think about the new format. A Solid Line-up of Symposia, Posters and Oral Presentations. From the Triennial Reproduction Symposium on Sunday to the dairy lactation and swine nutrition symposia on Thursday, there is a strong line-up of informative symposia. In addition, this is the first year we are presenting an extensive companion animal nutrition program, which we hope will leverage into future ASAS/ADSA meetings being the preferred forum for presentation of high-quality companion animal nutritional research. Over 25 symposia have been organized by the ADSA/ASAS program committees, in addition to several invited speakers. Your fellow scientists will be presenting about 1450 abstracts as either posters or oral presentations. Thanks to the ADSA/ASAS program committees and staff of FASS, ADSA, and ASAS. Special thanks to Chuck Schwab, 2003 Program Co-chair, Larry Benyshek, 2004 Program Chair, and all of the large group of program committees and chairs (please take a moment to thank your colleagues who took time to put this program together). A special thanks to the staff at ASAS, ADSA, and FASS for their dedicated work behind the scenes. We thank all of the many people involved, but I would particularly give my appreciation to Amy Kemp and Kim Surles, to Keely Roy and Lorena Nicholas, and to ADSA ED Brenda Carlson and to ASAS ED Ellen Bergfeld (who has not only provided great assistance for this meeting but has provided a legacy of accomplishments at ASAS that will be difficult to match). Look forward to seeing you in Phoenix.

The Congressional Insights program is a novel, stateof-the-art, interactive computer model designed to simulate a two-year term of office in Congress. This computer simulation and educational tool introduces participants to the legislative and political process on Capitol Hill. It illustrates why politicians must (or should) make some of the decisions they do. The program will introduce you to the pressures faced by members of Congress, show you the demands placed on their time, help you to understand that legislators are public officials whose actions are open to public scrutiny, and provide you with a better understanding of the role of elected officials and their staff. Participants are actively involved in this program. Participation is open to all student attendees and advisors. Experience with the political process is not needed to participate in this program.
