Brief Summary of Minutes of Annual Meeting

Date: May 21, 2007

Time: 9:00 a.m.

City: Miles City, Montana

Location: USDA-ARS Fort Keogh Livestock and Range Research Laboratory, Conference Room

Richard Waterman, 2007 Chairman, opened the meeting and welcomed us to Fort Keogh and Miles City, MT. We took time to go around the room and let each of the participants introduce themselves and tell us briefly about their degree emphases and institutions, their current job responsibilities, and their present research and/or extension focus areas.

The Chairman introduced Dr. Elaine Grings who gave us a 15-20 minute power-point presentation that provided the group with an overview and brief history of the Fort Keogh LARRL, and identified some of the past and current researchers and the projects that were historically done or are currently ongoing there at Fort Keogh LARRL.

Old Business: 1. Annual Report and Approval of Minutes - The Chairman provided us each with a hard copy of the WERA-110 2007 Annual Report. He referred the group to pages 5 through 9 in the 2007 Annual Report that contained the minutes of last years meeting and asked us to take a few minutes and read through the minutes in the report. C.Y. Hu pointed out that the word petition should be removed from his statement on the bottom of page 5. Bill Pinchak made a motion, seconded by Elaine Grings, that the minutes for the 2006 meeting in Vernon, TX be accepted and approved as amended. Motion passed unanimously.

2. New Look for Station Reports  Ken Olson presented an oral report from a subcommittee made up of he and Tim DelCurto. Items identified for discussion included: a. Focus of efforts should be on activities and provide visibility. b. Written reports should focus on accomplishments/impacts and should not duplicate the Western Section papers that are normally published near the same time of year. c. Reports should be more futuristic and focus on proposed cooperative efforts of participants, and results of discussions/brainstorming amongst the group. d. We need to be asking ourselves what is the value and use of our reports, who reads or needs them and how they are accessed. e. Maybe there should be greater emphasis at meetings on symposia/workshop planning. f. Definitely a bulleted list of accomplishments, and a show of common interests and integrated focus areas needs to be included. g. There is apparent need for how we structure the report, and organize the coordination and collaboration that goes on amongst participants. h. Ken agreed to prepare a written draft guidelines for the Structure and format of WERA-110 Annual Reports to be discussed and voted on prior to the end of the meeting. i. On Wednesday morning Ken Olson the draft guidelines were presented, discussed, revised and approved (see Attachment #1).

3. Richard Waterman reminded us of the key things that need to be included in our annual reports: a. A list of the participants b. Summary of the meeting to included a copy of the minutes. c. Accomplishments and impacts section to included plans of cooperative efforts for the coming year. d. List of publications submitted by the participants from the various institutions. e. That the minutes and annual report need to be submitted electronically to the NIMMS web site.

4. C.Y. Hu echoed Richards comments and reiterated the fact that there needs to be integration of focus, a reports which is based on the approved objectives, and a list of accomplishments (to include outcomes and impacts) that needs to be presented in a way that shows coordination, collaboration and overlap of efforts and a need for demonstrated rationality for regional emphasis/focus.

5. The question came up as to how our annual reports can be accessed and or linked to other sites so they are more readily available. a. Bill Pinchak reported that because of lack of resources ($ and personnel) our web site was currently on hold. b. Mark Petersen indicated that it was important for us to consider the key words and annual report format so that they are easily accessible by a Google or other search engine search. c. John Patterson indicated that it would probably take $2,000 to $5,000 /year to accomplish this task. d. Ken Olson indicated that we may want to consider writing a small grant to get funding to get the web site up and running. e. Bill Pinchak reiterated the need for changing the format of our annual reports, focusing on results related to our objectives with clear statement of outcomes and impacts to include interstate cooperative efforts, and including a list of our publications. He also indicated that the web site should facilitate living documents to include symposia activities, multiple state synergy and maybe even quarterly milestones. f. Rachel Endecott indicated she has had experience set up web sites and may be willing to assist the group. g. Bill Pinchak raised the question about who our audience is and how we anticipate the stakeholder/client to access the report and other information from the WERA-110 project. h. Jim Carpenter indicated that it would also be helpful if our list of publications included links to web sites when possible. We realize that in the case of some articles there are copyright concerns we should consider.

6. After a break Brett Hess was asked to make a presentation on the current financial situation for the group. He gave a historical overview of the initiation of need for funding (previous grazing conferences) and outlined some of the sources of income and expenses through the years. The bank account is currently at Wyoming and currently has a balance of $2,566.99. a. Brett was pointed out that this could be used as seed money to cover anticipated expensed for the upcoming grazing conference. b. C.Y. Hu reminded the group of the value of the registration fees for our meetings. c. Brett indicated that for those who desire copies he would provide a copy of the spreadsheet showing the various income and expenses through the years.

7. Jim Carpenter indicated that with the new scientists attending this year (Rachel and Shanna), that we should consider other new hires at institutions and expand the representation. a. Richard Waterman indicated that he had invited other people to the meeting this year via e-mail. His list of contacts (which was circulated to the group to review) was obtained from names provided by word of mouth or state web sites. A copy of the current list of project participants was also circulated so that any changes in contact information could be made. b. Both Richard and CY. Hu indicated that the key is the % attendance at our annual meetings so we need to ensure that if we are going to ask people to participate that they will attend our annual meetings on a regular basis. c. Brett Hess also reminded us that personal encouragement and invitation to join the group might be the most effective means. d. It was also pointed out that some states have multiple participants so those attending the annual meetings should be representing the various states and not just individual projects.

8. CSREES Report: Gary Cromwell handed out a report he had prepared for the WERA-110 meeting. The report included sections on CSREES Background, Farm Bill  CSREES Reorganization, FY 2007 and FY 2008 Budgets, CSREES Staffing, NRC Nutrient Requirements Series, Web Site and E-mail Addresses for CSREES, and National Information Management and Support system (NIMSS). He also provided us a U.S. Department of Agriculture organization flow chart and a list of the various administrators, deputy administrators and section leaders. In addition to covering the highlights of his written report Gary also talked about the reorganization in more detail and pointed out that budgets are being frozen so new hires are on hold and travel budgets are being reduced substantially.

9. Administrative Advisors Report: C.Y. Hu shared with the groupwhat has been on the minds of the Directors. Topics that he discussed included: a. Create 21  A big issue where there is attempt being made to raise the base funding for States (70% competitive, 30% capacity building). C.Y. will forward Richard a copy of the CREATE 21 assessment. b. On the research side Bioenergy is the top effort. This is a hugh effort with many new positions and many states receiving $150-200M. c. Sun Grant  one of the major leaders is South Dakota. Focus is on Bioenergy efforts to stimulate the economy in rural areas. There are currently 5 centers across the country: Cornell, Tennessee, Oregon State, Oklahoma state, and South Dakota. d. Every center receives $4M for four years (25% administrative and 75% proposals). e. Major issues in the West include land/water, human health and obesity. f. C.Y. highly supports the continuing of the WERA-110 project. Outputs and impacts are important to the administrators. Something else to consider seriously is because of our research what has been the impact on the beef industry (various ways to measure). g. C.Y. also provided us each with a copy of Appendix K, Midterm Review of Coordinating Committees and Education/Extension and Research Activities. He reminded us that the administrators would be meeting in June so try to get our minutes and annual reports on the NIMSS system quickly. Our next renewal is coming up soon so at next years meeting we need to focus our work around our next resubmission. He gave Richard a copy of the manual to use as a guide. h. C.Y. also questioned why we were a WERE and not a W project. He believes we should seriously reconsider and determine if it is better to remain a coordinating committee which does not carry a hatch # and have allocation of funds, or in the rewrite request we be W-110.

10. Our station reports were done differently this year. Richard had asked each participant prior to the meeting to submit two bullets that captured the essence of our research this past year (see Attachment #2). Using these bullets Richard put together a list of topics that was used to facilitate the groups discussion of what we have and need at our respective stations for techniques and resources to address the various topics (see Attachment #3). During our discussions the items were captured on the board and through assistance of Elaine and Rachel a summary was typed into the computer (see Attachment #4). Some of these discussions occurred on day 2 of the meeting.

11. After the afternoon break on the 1st day, we stopped our discussions on station reports and switched to developing an outline and planning for the 4th Grazing Livestock Nutrition Conference to be allied with the 2010 ASAS National meeting in Denver, CO (prior to national meetings). Richard again put together an excellent outline to be used for facilitation of our discussions and over the balance of our meeting we had brainstorming and discussion sessions and on Wednesday morning we finalized a summary of our accomplishments that reflects the current state of our planning, and assignment of responsibilities (see Attachment #5). Participants were encouraged to continue to coordinate and dialogue about the conference via e-mail. Things that we discussed included when and where it should be held, how we can promote the meeting (journals and popular press sources, develop a flyer to distribute at various national meetings, our WERA-110 Project web site), how we plan to get peer reviews (editorial board and standards) and publish the proceedings, who potential sponsors might be and ideas for grants to support our efforts, who our target audience will be and what we might establish as a registration fee (importance of a pre-registration date with cost advantage to get funding to cover some of the up-front costs that will be required), who we might approach to get continuing education credits for those who might desire/require them, and focus of conference (the major topics to be covered, names of potential speakers, and opportunity for abstracts and posters to be presented by participants. Need to coordinate with the national program committees to see if they would be willing to share in the cost of supporting invited speakers. Also identified potential dates and discussed possible timing for sequence of events at the meeting.

2008 Meeting: Jim Carpenter indicated that the 2008 Annual Meeting will be held on the Big Island in Hawaii, tentatively May 19-21. Jim will try to confirm dates and specific location soon so that people can be looking for cheap airline rates and plan family vacations in Hawaii if appropriate. Jim anticipates that we will either be meeting at the Kilauea Military Camp (KMC) near the volcano or at a hotel in the Kona or Waikaloa area. He also indicated that he would work on planning a couple of ranch tours and visits to other agriculture industries that people might not be familiar with. In addition to the finalizing our planning and coordination for the 4th Grazing Livestock Nutrition Conference prior to the 2010 ASAS-ADSA meeting in Denver, CO., we will need to spend a significant amount of our meeting next year on the rewrite of our project for continuation after September, 2009. We will also be implementing our new annual report format next year as well.

Election: The Nominating Committee consisting of Bill Pinchak and Richard Waterman nominated Bret Hess for secretary (2008)/chairman elect (2009) for the WERA-110 meeting to be held in Wyoming. Richard indicated that they had talked with Bret and he had agreed to accept the nomination. After the nomination was presented to the group Bret was elected unanimously.

Richard thanked the three graduate students who had made the effort to attend our meeting and each was asked to make a brief presentation on their Thesis/Dissertation projects. Mike Horvath is working with Shanna Ivey at New Mexico State University on impact of Methylglyoxal production in high carbohydrate/low protein diets or conditions with imbalance of protein in the diet. Travis Mulliniks is working with Mark Petersen at New Mexico State University assessing the value of corn gluten meal as a component of the supplement, and various levels of Ca propionate fed along with cottonseed meal. Platt Price is working with Bret Hess at the University of Wyoming assessing processed flaxseed with varying fatty acid proportions on lipid metabolism in cannulated sheep.

Guest Speakers and Field Tours: On Monday evening Ridley Block sponsored a reception and dinner and Mr. Bob Welling, Research Support Manager both gave a presentation and provided materials on Ridley Block Products and Operations. In addition, Dr. Eric Scholljegerdes gave an overview presentation on the research at the USDA-ARS Northern Great Plains Research Laboratory in Mandan, ND. On Tuesday morning we had a tour of the range research at Fort Keogh, LARRL and had field presentations by Dr. Matt Rinella at his weed research plots, Dr. Lance Vermeire at the grass plots where they are studying season productivity of various range grasses under various controlled moisture regimens, and Drs. Elaine Grings and Richard Waterman gave us an overview of their research programs and showed us the portable temporary holding facilities they have constructed there at Fort Keogh to allow individual animal supplement consumption and data/sample collection. That afternoon we visited the reproductive herd research facilities and Dr. Tom Geary gave us a tour and explained the various projects he currently has in progress and is planning. We then went to the heifer rearing facility where Dr. Andy Roberts both explained and gave us a demonstration of the computerized animal identification system being used and the types of data and records that can be generated. He also gave us a tour of the barn where they use Calan gates to get individual intake and performance data for growing replacement animals with restricted intake.

Attachment #1 to WERA-110 Annual Meeting Minutes Structure and Format of WERA-110 Annual Reports

Our intent is to develop a report that is more streamlined, is adaptable to publication on a web page as opposed to print, and provides a contextual sense of the collaboration and integration among stations as opposed to reporting the activities of each station separately. Thus, the major change will be that we will no longer publish a compilation of individual station reports. Instead, we will organize the report by each objective, with a compilation within objective of the contribution to that objective by each station. This should serve two purposes. First, it will make it more readily obvious to the reader that there is a high level of interaction and collaboration among our committee members. Second, it will help us to more directly assess our progress toward fulfilling our objectives and allow us to make annual adjustments as needed.

Prior to each annual meeting, the secretary will solicit one to three bullets from each participant indicating major accomplishments over the past year in relation to WERA-110 objectives. Each bullet should be a one or two sentence statement describing the accomplishment. If a bullet is the result of a collaborative effort among stations, that should be indicated in the bullet. Each participant should indicate which objective each bullet is a contribution to. The secretary will then organize the bullets by objective so the list of bullets can be distributed at the beginning of the annual meeting. This stratification of annual reporting by subject matter rather than by station will simplify identification of shared and common efforts and stimulate discussion of opportunities for collaboration. One of the greatest values of this committee has been the communication and collegiality among the participants. This format should further promote that value.

This compiled report will provide the basis for annual reporting of accomplishments and impacts. To complete the annual report to NIMMS, the secretary will add accomplishments of the entire group, such as planning and sponsoring symposia. The secretary should also include outcomes and impacts from the effort of the group for the past year. We need to be sure that we are showing outcomes and impacts commensurate with the expectations of RCIC.

At the time that the secretary requests the bullets, he/she will also request a list of publications from each participating station that will be incorporated into the annual report to NIMMS. Attachment #2 to WERA-110 Annual Meeting Minutes Research Emphasis

" Study of rate of dry matter and insoluble macro-mineral release from alfalfa and tropical pasture grasses during in situ digestion trials of cattle and assessment of NRC/CNPC computer models for predicting cow/calf productivity on tropical Kikuyu grass (Penesitum clandestinum) pastures. The primary objective of this research was to determine the proportion or levels of minerals actually released in the rumen, and are therefore available to the animal for productive purposes, and to compare the release of minerals with the digestion of dry matter in the rumen and to test the effectiveness of the models for tropical conditions. " Assessment of Effects of aeration and sewage biosolids on improved kikuyugrass pasture productivity and nutrient composition. Specific objective of this 2-yr study were to determine if well-fertilized (N-P-K) pastures would respond to aeration or Milorganite® (biosolid/ sewage sludge) application (at equal N levels) with improved yield and/or changes in nutrient and macro-/micro-mineral composition. We have also been evaluating the effects of aeration, fertilization, season (temperature, rainfall, and month of harvest), age of regrowth, and/or pasture management on grass productivity and changes in nutrient and mineral composition.

Technology transfer was accomplished through 18 peer-reviewed publications, 23 proceedings, 25 abstracts, and over 40 technology transfer forums from June 2006 through May 2007. 1. Mark Petersen, New Mexico State University, and Jim Sprinkle, Arizona State Univeristy, have been working together to develop a Decision Making Tree for range supplementation.

2. Had good discussions on current project accomplishments by various participants, and had a great brainstorming session on our present state and needs for techniques and resources for various topics of common research and extension interests.

3. Conducted very successful initial planning sessions for the 4th Grazing Livestock Nutrition Conference to be held in prior to the 2010 national ASAS-ADSA meetings in Denver, CO.

4. During (scheduled networking breaks) and evenings/after the meetings time was available for extension coordination efforts among personnel from Montana, Arizona and South Dakota; manuscript preparation between Shanna Ivey, New Mexico State University, and Richard Waterman, Fort Keogh LARRL; and coordination for WERA-110 Project personnel to meet with both university research and extension staff and ranchers in Hawaii prior to or after the 2010 meetings about strategic supplementation decision matrices.

5. Professional development was a key part of our annual meeting. We had speakers from both industry and research areas outside our areas of expertise, we took field tours to broaden our perspectives, and we had healthy discussions and were exposed to areas of research that were different from many of our individual focus/expertise.

6. Current and future cooperative research efforts were discussed amongst various researchers and Bret Hess hauled cattle from Fort Keogh LARRL to Wyoming to use for research.

7. Had good graduate student participation at the meeting and want to encourage that this effort, which addressed our project objective 3, continue in the future.

8. Spent a considerable amount of time talking about the format of project annual reports and how we can make our efforts more user friendly and accessible to our very diverse clientele.
