Brief Summary of Minutes of Annual Meeting

The annual meeting of the NCR-57 Regional Committee on Swine Reproduction was held in the Department of Animal Science, University of Wisconsin, Madison. The committee chairman, Dr. Brett White, called the meeting to order at 8:15 am, May 25, 2005; the proposed agenda was accepted. Dr. Dan Schaefer welcomed the group to University of Wisconsin and provided a summary of the programs and activities within his department. Administrative Advisor, Dr. Baker, reported that the committee was required to change its name to reflect the common USDA committee nomenclature. After a brief discussion, the committee unanimously agreed to adopt the name change from NCR-57 to NCERA-57. Dr. Mark Mirando, acting for USDA/CSREES/PAS advisor Dr. Deb Hamernik, distributed a handout summarizing personnel changes within the agency and providing details about competitive programs. Station reports were presented during the morning and afternoon of May 25 and the morning of May 26. Following station reports on May 25, the committee toured the new Minitube Biotechnology Center. During the business meeting, John Parrish was elected as secretary. The officers for the year are Ford (Chair), Kirkwood (Chair elect) and Parrish (Secretary). The dates and location for the 2006 meeting were discussed and will be finalized in association with Billy Flowers in North Carolina. A steering committee was formed consisting of Drs. Flowers, Guthrie, and Safranski. Regarding a committee web page, Dr. Parrish requested that members forward to him pig reproduction pictures (eg. AI and farrowing). Also, links to other sites (eg. personal web pages) and details of previous and future symposia should be sent to Dr. Parrish. Dr. Duane Davis initiated some discussion on the NCERA-57 committee submitting an integrated proposal to NRI. Possible subject areas suggested were sperm assessment and seasonal effects on semen quality (Dr. Guthrie) and some aspect of animal welfare (Dr. Anderson). A steering committee was proposed consisting of Drs. Davis, Parrish, Guthrie, Miller, and Kirkwood.

1. Re-classification as an Education/Extension and Research committee was adopted. The official name is changed from NCR-57 to NCERA-57 2. Publications produced by committee members and their associates during the past year are listed 3. The dates and location were chosen for the third workshop to be held prior to the 2006 meeting. Plans for the Coming Year: 1. Complete the planning of the third workshop to be held in association with the 2006 meeting. The topics and location were chosen to meet the aim of increasing interaction with extension educators. A committee was established to achieve this aim. 2. During 2005, continue development of the NCERA-57 web page. This will include a history of the committee. 3. Two study areas were identified and a committee struck to formulate and submit for NRI funding at least one proposal integrating teaching, extension and research.
