Status: Approved
Basic Information
- Project No. and Title: WCC110 : Improving Ruminant Use of Forages in Sustainable Production Systems for the Western U.S.
- Period Covered: 04/01/1999 to 06/01/2000
- Date of Report: 09/09/2002
- Annual Meeting Dates: 06/23/2000 to 06/24/2000
Participants
Ed Huston (TAMU); Pat Hatfield (MSU); Larry Rittenhouse (CSU); Tim DelCurto (EOARC); Jim Carpenter (U of H); and Bok Sowell (MSU); Bret Hess (UW); Ken Olson (USU); Ray Ansotegui (MSU); The list of guests included: Dr. Rod Preston; Dr. David Bohnert (EOES); Ken Walburger (OSU graduate student); Clint Stonecipher (USU research technician); Amy Davis (USU graduate student); Raul Lina (USU graduate student); Dr. Shadi Hamadeh (MSU visiting professor, American University at Beirut)
The meeting of WCC-110 was called to order by Chairman Ed Huston. Station reports were given by all members in attendance.
After station reports there was discussion of the goals of WCC-110 and the benefits of attending coordinating committee meetings which is the interchange of ideas, but we must provide our advisors with documentation of accountability. Ken read the Educational Plan section of the petition, which stated that we will publish an experiment station bulletin on strategic supplementation and make contributions to the Cattlemans Library. We had also indicated that we would explore the possibility of dissemination of research using a web site(s) or CD-ROM libraries.
Pat motioned for members to submit written reports. This motion was seconded by Tim and passed unanimously. Reports are to be submitted to the secretary before our annual meeting. These reports will be a one-page summary of research events with itemized contributions to the coordinating committee, and should be limited on graphics. Both a hardcopy and electronic copy of the reports will be required, as will a list of publications. The secretary will see that the reports are consistent in format, bind them, and distribute them at the annual meetings.
New officers were elected to serve for next year:
Bret Hess (UW), Chairman
Pat Hatfield (MSU), Secretary

Accomplishments
The objectives of the WCC-110 are to share results of recent research efforts, foster new research ideas, coordinate future cooperative scientific efforts, and to facilitate the transfer of technology to livestock producers, extension personnel, and others in animal industries. To this end, the WCC-110 identifies critical/key research issues related to forage utilization by ruminants and helps members develop specific research programs in priority areas. In addition to the advancement of individual research, teaching, and extension programs, the group is active in publishing and sponsoring symposiums on topics of current interest
