Accomplishments

Report from Paul Rodgers, American Sheep Industry, Association. Paul thanked the committee for the opportunity to meet with them and to continue the association between the National Sheep Improvement Program (NSIP) Technical Committee meeting and NCR-190. The article summarizing the findings of the cooperative project conducted by committee members, Length of docked tail and incidence of rectal prolapse in lambs, was written by D. Thomas and has been submitted to the Journal of Animal Science. Two other publications summarizing the cooperative efforts of NCR-190 members on: Crossbreeding K. Leymaster, and Out of Season Breeding D. Notter are also in the final stages of review. Both of these articles will be published in a special issue of the Sheep and Goat Research Journal. Following publication there, Leymaster and Notter will take the initiative to edit the articles as necessary for further publication and distribution in industry channels including popular press magazines, ASI newletter, and electronic media options.

Accomplishments

The greatest short term impact of this committee is the publication of papers on crossbreeding and seasonality. These papers have been published in Journals along with distributed to popular press. It was estimated that over 40,000 subscribers have seen these publications. Additionally, these publications have been made available on the web at the primary authors institution and American Sheep Industry Associatoin web site. Seasonality has been identified as a critical factor limiting the American Sheep Industry. Summarization of work conducted by NCR 190 and previously by NC 111 committees provides producer with the information necessary to successfully over come seasonality in their sheep operations.

Brief Summary of Minutes

NCR 190 Annual Meeting Minutes

June 29, 2004

Duluth, Minnesota

Chairman Don Ely called the meeting to order. Every participating institution was represented with the exception of Ohio State, which was the best attendance in several years. The first order of business was to approve the 2003 Minutes as presented in the Annual Report. Dan Morrical moved and Kreg Leymaster seconded the motion to approve the minutes as presented. The motion was approved.

Old business began with a discussion of publication of information produced from the committee in the popular press.

New business began with an administrative report from Dan Schaefer. Dan reported the new project was approved. Appreciation was expressed to Kreg Leymaster, Don Ely, and Dan Morrical for taking the lead on writing the new project. Dan Schaefer emphasized the need to highlight committee technology transfer efforts, collaborative efforts, committee accomplishments, and impact of the committee in future reports. Much discussion followed on technology transfer and collaborative efforts of the committee. Howard Meyer suggested the secretary be sent by email a list of collaborative efforts of the committee from the current 5-year project for the annual report. It was also suggested the proceedings of future meetings of the committee include a section on collaborative efforts. Dan Schaefer then reported on the committee?s web site. All participants need to access the website and verify name and contact information. The website also has a listserve to facilitate emailing committee members. Questions arose about linking to and from the website as well as posting joint committee papers on the website. The possibility of advertising the website was also suggested. Dan then praised the committee for the number of members in attendance and the number of new members. He also emphasized the importance of attendance. Dan then added as an individual that he thought product is an important component of sheep production for the committee to be sure to include.

The annual report was then further discussed. Dan Morrical and Jay Daniel were assigned to write the report.

Larry Miller gave an update from CSREES. A written report was included in the meeting proceedings. He introduced Paul Lewis, a sheep producer and member of the Sheep Center Board of Directors. Larry announced the Sheep Center call for proposals, which has previously funded some research conducted by NCR-190 members, due in October and the National Animal Germplasm Program, which involves some NCR-190 members, conference in November to be held in Cheyenne, Wyoming. Larry also informed the committee that next year NCR committees will be required to submit accomplishments of the committee in addition to minutes. He also commented on the extensive participation in the meetings.

Paul Rodgers gave an update from the American Sheep Industry Association. First, Paul thanked the committee for the opportunity to attend and expressed appreciation for active support of industry and outreach by the committee. He expressed ASI?s willingness to aid with the outreach efforts of the committee. He then addressed several areas of ASI activity including: BSE impact on sheep industry and the ASI response to the recent case of BSE in a Canadian cow in the US, market access to Mexico, mandatory price reporting re-authorization, Sheep Center funding, scrapie eradication program funding, minor use/minor species legislation, price insurance for sheep, animal identification, and the upcoming referendum on the sheep checkoff. Paul also announced that last month imports of lamb exceeded domestic production for the first time, the ewe lamb retention program will be extended with the sign-up beginning next month, and domestic wool prices are within 10% of Australian wool prices for all classes. He extended an invitation for the committee members to attend the ASI annual convention next year in Reno, Nevada. He then addressed questions regarding sheep rendering, COOL, and the up-coming checkoff referendum.

The committee then broke for lunch. At 12:45 pm, the meeting was reconvened.

Margaret Benson gave an update on the progress of the committee to produce of the National Research Council Nutrient Requirements for Small Ruminants. It will cover sheep, goats, and other small ruminants. The NRC is expected to be completed in approximately 2 years. Discussion followed on the members of the NRC committee, the information to be included in the NRC, and the form of the publication to be produced. Dan Waldron presented a resolution regarding the NRC. The resolution was discussed and changes were suggested. It was decided the resolution committee would present a revised resolution later in the meeting.

The nominating committee chaired by Howard Meyer nominated Dan Morrical for Chairman, Jay Daniel for Vice Chair, and Stephan Wildus for Secretary. Mike Neary moved and Margaret Benson seconded the motion to close nominations and cast a unanimous ballot. The motion was approved. Howard Meyer then passed the floor to Stephan Wildus, who offered to host the 2005 meetings at Virginia State University in conjunction with a Hair Sheep Symposium in late June. Kreg Leymaster moved and Dan Morrical seconded a motion to accept the invitation for Virginia State University to host the 2005 meetings. The motion passed. Discussion then proceeded on the possibility of co-sponsoring a Hair Sheep Symposium with Virginia State University. Mike Neary moved and Dan Morrical seconded a motion to appoint a committee to explore the possibility of NCR-190 co-sponsoring a symposium and to report to the executive committee. The motion passed. Stephen Wildus, Dave Notter, and Bob Godfrey were appointed the committee.

The resolution committee chaired by Dan Waldron presented the resolutions for adoption. The resolutions were discussed and revised to the following resolutions:

Resolution 1: Be it resolved, the current members of NCR-190 express warm welcome to those institutions (University of the Virgin Islands, USDA-Booneville, Pennsylvania State University, and University of California-Davis) which will become a part of the new project starting in 2004.

Resolution 2: Be it resolved, the members of NCR-190 express gratitude to Dave Thomas, Yves Berger, and the rest of the University of Wisconsin staff for their hospitality and a well organized meeting.

Resolution 3: Be it resolved, the members of NCR-190 wish to express condolences to the families, friends, and colleagues of Bob Jordan, Bill Boylan, and Upson Garrigus. Their inputs into our programs have been important and will have a lasting impact.

Resolution 4: Be it resolved, the NCR-190 committee wishes to thank the National Research Council of the National Academies for going forward with the production of Nutritional Requirements of Small Ruminants. We especially express appreciation for the contributions from National Sheep Industry Improvement Center, American Sheep Industry Association, USDA-CSREES, Montana State University, Texas A&M University, and New Mexico State University.

Be it further resolved that while we recognize the efficiency of combining the requirements into a single publication. We believe that the document should be structured so that information on sheep is in a clearly defined section. The information should be based on published science, and be easily accessible and user friendly.

Mike Neary moved and Howard Meyers seconded a motion that the resolutions be accepted. The motion passed, and the secretary was instructed to ensure the resolutions were forwarded to the appropriate parties.

Dave Notter moved to adjourn and Dan Morrical seconded. The motion passed.
