The annual meeting of NCERA 190 committee was held at Virginia State University, Petersburg, VA. The business meeting was called to order by chairman Dr. Dan Morrical on June 21, 2005, at 8:15 AM. Dr. Dan Schaefer presented an administrative update and explained the changes in designation for regional projects, and the committee unanimously selected the NCERA designation. He also explained that a new list of committee members was being prepared for the revised project, and that the health of the committee is reflected in the attendance of committee members at the annual meeting, collaborative efforts, progress in achieving objectives, capturing external funding (leverage committee strength), technology transfer, development of an impact statement. Discussion arose on how committee members get on and off the official station list, and it was recommended that the issue of non-attending members should be addressed by Dr. Schaefer. The USDA-CSREES report was presented by Larry Miller, who gave updates on staff changes within USDA, the genome mapping efforts for various species, the revision of the NRC requirements for small ruminants, the National Sheep Industry Improvement Center, and USDA portfolio reviews. He also presented an update on the USDA budget, and considerations to reduce formula funding by half, to be replaced with competitive programs. Updates on activities by the American Sheep Industry Association were provided by three speakers. Dr. Lyndon Irwin, presented an update on the National Animal Identification Program, NRC nutrient requirements for small ruminants, and agro-terrorism as they relate to the sheep industry. Dr. Lowell Slyter gave an update on the status of the Sheep and Goat Research Journal, which will be available free on-line through the ASI web site, and funded through page charges. Papers will be published continuously as they are reviewed. Paul Rodgers reported on the referendum passed to approve the lamb check off, with funds to go to the American Lamb Board, a new Sheep Price Risk Insurance program, and a new "Try Lamb" initiative, as joint effort between the U.S. and Australia. The NSIP update was provided by Dr. James Morgan, who presented a summary table of activities by breed. New traits are being evaluated for inclusion in the NSIP program, such as accelerated lambing (Polypay), fecal egg count (Katahdin), and carcass scanning (MARC 8 Composite) EPDs. Boer goats will be part of NSIP, and Kiko and Alpacas are under consideration. An update on the development of new NRC requirements for small ruminants was provided Dr. Larry Miller, and he indicated that the final version of the document will have separate sections for sheep and goats. Dr. Dan Morrical presented a proposal by Iowa State University to provide ration balancing software to NRC. On behalf of resolutions committee Dr. Joan Burke presented eight resolutions that recognized various individuals and organizations for contributions NCERA 190 and the sheep industry, urged the American Lamb Board to direct a portion of their producer check-off funds to the support of sheep production research to improve the competitiveness of the U.S. sheep producers, and requested that the National Association of Fairs institute a sheep tail docking rule in the interest of animal well-being. All resolutions were passed unanimously. Dr. Jay Daniel, Chair, Dr. Stephan Wildeus, Vice-Chair, Dr. Joan Burke, Secretary, were elected as officers. Dr. Joan Burke agreed to host the 2006 meeting at the USDA-ARS Research Station in Booneville, AR, in mid-June 2006. The committee discussed the participation of non-members at the meeting. Concerns were raised about the appearance of information in public domain without review and author approval, and that presence of non-members may prevent scientists from discussing preliminary data freely. After input from a number of committee members, a motion was passed to extend invitations to industry organization and institutional representatives, as well as institutions that are working in sheep research. Guests can also be sponsored by committee members, and the chair will make an announcement at the beginning of the meeting to adhere to the statement on the cover of the proceedings regarding the use of the material presented. The business meeting was then adjourned. Station reports were presented all day Monday, June 20, and again Tuesday, June 21, after the business meeting. The meeting concluded with a tour of the Virginia State University Small Ruminant Facilities on Tuesday afternoon and a joint hair sheep lamb dinner with participants of the Hair Sheep Workshop following the NCERA-190 meeting.

Accomplishments

NCERA 190 members cooperated on two projects using the MARC Composite rams, with one of the projects involving the USDA-ARS Meat Animal Research Center and Texas A&M University, and a second project involving the USDA-ARS Meat Animal Research Center, the USDA-ARS Sheep Experiment Station, and Virginia Tech. A cooperative project evaluating copper wire particles for the control of gastrointestinal nematode parasites is in progress with NCERA 190 committee members from the USDA-ARS Dale Bumpers Small Farm Research Center and Iowa State University. Cooperative research was facilitated through the exchange of hair sheep germplasm between NCERA 190 committee members from the University of the Virgin Islands and Virginia State University. Joint research on the molecular biology of the Callipyge gene is in progress between NCERA 190 committee members from Utah State University and Purdue University.

Impacts

  1. The committee co-sponsored a hair sheep workshop that was held in conjunction with the NCREA 190 meeting at Virginia State University. The workshop was funded by a grant from the National Sheep Industry Improvement Center ($15,000) to Virgina State University (Stephan Wildeus). The Workshop provided an overview of current hair sheep research and the workshop material will be summarized on a web-site oriented towards producers.
  2. The committee co-sponsored a symposium on Management of Gastrointestinal Nematodes in Sheep at 2005 Annual Meeting of the American Society of Animal Science. The symposium was organized by committee member Dr. Joan Burke and funded by a grant of the National Sheep Industry Improvement Center to the American Society of Animal Science. Audio-visual proceedings of the Symposium will be available through the American Sheep Industry Association (ASI).
  3. Activities of the NCERA 190 committee, especially by committee members Dr. David Thomas and Dr. Yves Berger, in dairy sheep research and extension have contributed to the growth of the U.S. dairy sheep industry.
  4. The NCERA 190 committee is involved in activities of the National Sheep Industry Improvement Program (NSIP) through Dr. Dave Notter, and contributed to the expansion of the program in breeds and number of animals enrolled.
