MINUTES
The Western Region Coordinating Committee for Beef Cattle Breeding Research (WCC-1) convened in Havre on June 4, 2003 and Lethbridge on June 6, 2003. Ten people were in attendance at Havre (all but Denny Crews) and ten (all but Don Kress) at Lethbridge.
Committee Renewal
The committee was approved for 5 more years and was allowed to keep the WCC-1 designation that it has always had. During the approval process, it was suggested that more extension faculty be involved with the group. It was noted that many of the members that were unable to attend this year had extension appointments.
2004 Meeting
The location, date, and chairperson for the 2004 WCC-1 meeting were agreed upon as follows:
Location: Sioux Falls, South Dakota (in conjunction with 2004 Beef Improvement Federation annual meeting)
Date: May 23-24, 2004 (Sunday and Monday)
Chair: Denny Crews, Ag-Canada
Residual Feed Intake
Denny Crews presented some results of research being conducted at the Lethbridge Research Center involving residual feed intake and feed efficiency in feedlot cattle.
Website
Milt Thomas presented the status of the WCC-1 website. Currently, the website is offline, but will be reactivated with the new Animal and Range Science department server at New Mexico State University.
Any publications of interest that are relative to WCC-1 should be emailed to Milt to be added to the reference list of the website.
It was also discussed that any links of interest should be added to the website. These include links to all of the departments represented by WCC-1, Ag-Canada, and Fort Keogh. Also, the webmaster at New Mexico State University will contact other organizations to add the WCC-1 webpage as a link. These include BIF, breed associations, each members department, Oklahoma State Universitys Virtual Livestock page, Western Section of the American Society of Animal Science, National Cattlemens Beef Association, and Canadian Cattlemens Association.
A suggestion was also made to make class notes available on the website for graduate student education.
Graduate Education
The idea of combining resources in order to allow for more available coursework for graduate students was suggested. This would help fill holes in graduate education in each of the WCC-1 universities which have no more than two faculty members in animal breeding. Ideas suggested were a course to be conducted during national Animal Science meetings or to conduct an online class similar to what New Mexico State University and the University of Arizona have done in the past. Mark Enns volunteered to find out what would need to be done to have a shortcourse before or during 2004 national Animal Science meetings.
Contact and Resource Information
Mark Enns presented the online form that was developed to address Objective 3 of the current petition which was to maintain a record of resources on pedigreed populations that could be used in quantitative and/or molecular studies. The form would allow members of WCC-1 to list the resources available at each institution. Suggested additions to the form included a Comments section, general categories of data type (growth, carcass, etc.), and years that the data includes. A suggestion was also made to change Number of DNA Samples to Number of Tissue Samples.
Station Reports
Station reports were given by members in attendance.
Survival Analysis
The meeting concluded with a presentation by Phoenix Rogers of her thesis project on survival analysis which will also be presented at national Animal Science meetings in Phoenix, AZ.
