Brief Summary of Minutes

The group met in Estes Park the evening prior to the 4th Grazing Livestock Nutrition Conference (GLNC).

Discussion of how conference would be managed, namely how much time would be allowed for questions. Mark suggested that we allow questions for our international speakers go on as long as reasonable, the group agreed. A microphone would be available to travel around the room so that each question could be heard by those attending as well as those who subscribed to the Webinar.

Bret gave a brief treasurers report to the group. Prior to the conference, W-1012 was carrying a balance of $6,000 and to date had deposited monies for the GLNC received from pre-conference registrations ($20,975), AFRI grant ($10,000), Western Section ASAS ($3,000), Ag Experiment stations ($4,200), and sponsorships ($3,500) with more was expected to come in. So, to date (prior to conference) expenditures were $3,486 and other expenditures were expected to be $29,762 for a total expected cost of $33,248 for the conference.

Post-conference:
Bret moved to provide Dr. McLennan with money to offset travel expenses. The group agreed and Ken suggested that it be equal to that of Dr. Dove, therefore the group agreed that Dr. McLennan receive $1,200 to offset travel expenses.

Bret asked if the group felt it would be necessary to print more hard copies of the proceedings and if so, it would need to be in 100 book lots. Mark suggested that since we have it in a pdf, we could print off on demand. The group agreed

A list for those who may need or want a CD should be developed and copies will be provided. Bret will hold the CDs and all requests should go through him.

Richard gave a brief summary of GLNC attendance. There were 151 confirmed registrants plus 12 onsite registrations for a total of 163 registrants. Thirteen CDs of the previous three GLNC were sold. Nine registrations were received for the webinar, seven from the United States, one from Uruguay, and one from Australia. Overall there were 10 countries represented at the meeting.

CY gave a report to our group. In this report he indicated that by being designated as a W or a Regional Committee we were now able to solicit money for research and travel from our respective Ag. Experiment stations. We will have a mid-term review within 3 years. For this review the GLNC will be an excellent example of a synergistic output. CY also strongly advised that the group start to develop a relationship with scientists from China and that perhaps holding our annual meeting somewhere in China would be very advantageous to us. Others in the group felt this was a good suggestion and a number of the members stated that they had contacts in China that would be good to work with.

Establishment of the next chair was discussed and Dr. Ken Olson from SDSU graciously accepted the nomination.

Finally, discussions over the work needed to meet Objective 1 began. A number of those from the group visited with Dr. Dove and found that Dr. David Forbe has one of the best labs in the U.S. for alkane analysis. Both Univ. of Wyoming and NMSU have samples slated to be analyzed for alkanes. The group came up with work plan for this year in an effort to accomplish Objective 1. One is to continue to work on refining the method, which Univ. of Wyoming, Ft. Keogh, and NMSU are working on. Second, all participants will development an inventory of samples that will contribute to a regional database of forage samples. After which, the groups whom have laboratories that are capable of running the alkane procedure will all receive a subset of forage samples from each group and compare results.

Accomplishments

The primary activity completed this year for W-1012 was hosting the 4th Grazing Livestock Nutrition Conference in Estes Park, CO July 8th through the 10th, 2010. The group invited two international speakers from Australia and a number of speakers from the United States. There were 163 attendees from which 10 countries were represented. In addition, 28 abstracts were presented over the course of the meeting. This conference contributed to our third objective focused on dissemination and translation of research-based management strategies to stakeholders for improving ruminant use in sustainable forage production systems.<br /> <br /> <br /> Short term outcomes from W-1012 were the provision of monies for New investigators/junior scientist and graduate student travel awards to the 4th Grazing Livestock Nutrition Conference in an effort to meet our fourth objective of providing professional development and mentoring opportunities for committee participants, young scientists, stakeholders, and graduate students.<br /> <br /> Outputs for the group as a whole consisted of 41 peer-reviewed journal articles and 36 extension or popular press articles. Grants and sponsorship for the 4th Grazoing Livestock Nutrition Conference that totaled $21,000 ($10,000 USDA-AFRI Conference Grant and $11,000 in sponsorship)<br /> <br /> Important Milestone accomplished for 2010 was progress made toward standardization of n-alkane procedures across states. Finalized and hosted the 4th Grazing Livestock Nutrition Conference.<br /> <br /> <br /> <br />

Brief Summary of Minutes

Brief Summary of Minutes of the Annual Meeting

The group met in Miles City, MT immediately before the meeting of the Western Section of the American Society of Animal Science.

Treasurers report (Bret Hess):
- Current Balance is $13,745.61. The 4th GLNC netted $10,977.62.
- The current balance is in a revolving account at the University of Wyoming AES office (Bret has access).
- Allison Meyer replaces Bret as treasurer (UW member is treasurer because that is where the account is).
- The treasurers report was approved as presented

Review of 4th Grazing Livestock Nutrition Conference (Richard Waterman)
- The conference was dedicated to Frank Hinds, Don Clanton, and Joe Wallace in honor of their significant contributions to the founding of the Grazing Livestock Nutrition Conference series.
- We received letter of thanks from Joe Wallace.
-We discussed the value of the pre-conference tour with Hugh Dove. The consensus was that it was highly productive for all of us that were involved.
- We discussed the proceedings
-- We decided to put Acrobat pdf files of all 4 conferences on the NIMSS web site.
-- We talked about web presence
-- We will continue to use NIMSS as opposed to having our own web site that we have to maintain.

Administrative Advisor update (Bret Hess)
- CY Hu is no longer in AES at the University of Hawaii (he is now in upper admin.), so Bret is our newly appointed AA.
- RCIC is now called Multi-State Review Committee (MRC)
- MRC has agreed to change proposal review:
-- 1 submission date per year - January 15
-- We need to start drafting a renewal in year 4 (2013 for us)
-- Our annual report will be due on August 15 (60 d after annual meeting)
--- We need to continue to demonstrate coordination among stations
--- We need to show progress toward objectives, milestones
--- We need to show attendance by participants at meetings.
- China/Mongolia exchange
-- CY would probably still support and help us to coordinate this activity.
--- We briefly discussed the possibility of applying for a NIFA travel grant?
-- Dale Zobell is going to Mongolia in 3 weeks and will make contacts
--- It may be a possibility for him to serve as coordinator of this activity.

NIFA update (Bret Hess)
- Current federal fiscal year funding for Hatch and McEntire-Stennis were increased 10% for Hatch and 13% for McEntire-Stennis
-- Earmarks and special grants were reduced, so this compensated
- Smith-Lever funding was cut by 1.2% - better than the 10% that had been proposed
- Funding to NIFA for AFRI was held steady.
-- Climate change  there wont be $5 million grants like originally planned  that had been a gamble on increasing level of funding  previous year grants were awarded forward based on expected funding  so now they are short for new projects  there will not be any more big awards  rather a return to integrated or single investigator awards.
-- Global food security was also changed to more single investigator and less big awards.
-- No one knows when current fiscal year RFA will be released
- Funding levels in the upcoming new farm bill look dismal (all of the following compared to fy11):
-- 12% cut for ARS
-- 16% cut for NIFA
-- 12% cut for Hatch
-- 12% cut in Smith-Lever
-- 9% cut in McEntire-Stennis
-- 30.6% cut in AFRI
-- Special grants were reduced by 97% in FY11, another 56% will be cut in FY12
-- $0 for education grants (Higher Ed Challenge Grants)
-- This has already all passed in House bill, being debated in Senate

Chris Allison presentation
- Chris presented background information and a request for a concern about calculation of animal unit equivalents (AUE) on federal agency (public) land, particularly in Region 3 of USFS. They have a range of AUE that is applied across allotments (ranges from 1.32 to 1.5 AUE per cow-calf pair). How AUE is applied from on allotment to another seems arbitrary and capricious.
- Chris requested that this committee consider a response because of our expertise concerning forage consumption from rangeland by grazing livestock.
- We discussed option for a response from this committee. We are considering a synthesis paper in Rangeland Ecology and Management  Eric We are considering an REM synthesis paper  Eric will develop the details.

Station Reports
- Each of the 4 objectives of this project were discussed with each station indicating their progress toward that objective.

NSF RFA to fund our research
- We discussed submitting an application in 2012
- This RFA is intended to support group research, to support underserved populations, and to work together on a common theme, such as an approach
- Eric will spearhead the process
- Eric will email the link to us.

Elections
- Shauna was elected new secretary

Accomplishments

Objective 1. Validate the utility and repeatability of the alkane assay for measuring fecal output by grazing ruminant animals.<br /> <br /> COLORADO STATE UNIVERSITY<br /> CSU collected samples of 3 winter forages (vegetative wheat pasture, cornstalks and mature stockpiled Sudex) for use in validating alkane assays. These samples were collected using 2 rumenally cannulated steers on March 1, 2012.<br /> NEW MEXICO STATE UNIVERSITY<br /> Evaluation of alkane assay and preparation of samples containing beeswax have been initiated. Likewise, a library of masticate samples is being collected for future analysis.<br /> NORTH DAKOTA STATE UNIVERSITY<br /> Forage samples are in hand (masticate and other forms of sampling) from previous studies and are available for forwarding to laboratories for alkane analysis as needed<br /> SOUTH DAKOTA STATE UNIVERSITY<br /> Collected diet samples to develop library of diets from Northern Mixed Prairie rangeland from north-central South Dakota for future alkane analysis.<br /> UNIVERSITY OF WYOMING<br /> Forage samples from previous studies are available for analysis. No additional progress has been made at UW this year.<br /> VIRGINIA TECH<br /> By using both n-alkane and long chain alcohol concentrations in forages, the botanical composition of simple test diets (various mixtures of red clover and fescue) were accurately estimated. In collaboration with the US Meat Animal Research Center, this approach is being extended to define the plant-wax marker profiles of cool and warm season forages in the central plains environment.<br /> Using n-alkane profiles alone, estimates of diet choices of heifers at two ages (post-weaning, yearling) when offered cubed red clover and fescue hay ad libitum very reliably reflected their actual choices. A preference of larger frame sized heifers for the more nutritious forage  red clover  was clearly evident in their diet selection.<br /> USDA/ARS FORT KEOGH<br /> Obtained protocol for GC analysis and have collected rumen extrusa samples that have been freeze dried.<br /> <br /> Objective 2. Identify the shortcoming of the 1996/2000 Beef NRC for cows grazing in Western rangeland environments.<br /> <br /> NEW MEXICO STATE UNIVERSITY  <br /> An experiment was conducted to develop and test the efficacy of a rumen protection method for Arginine HCl. An experiment was initiated aimed at evaluating the effects of rumen protected Arginine HCl on fetal development in mature beef cows grazing native rangeland.<br /> NORTH DAKOTA STATE UNIVERSITY<br /> Investigated approaches for strategic supplementation strategies for ruminants.<br /> OREGON STATE UNIVERSITY<br /> Impact of nutrition during sire development on daughter performance and grazing behavior in Intermountain West forested meadows. This two year project is looking at the influence of nutritional background during sire development on weight gain, change in BCS, and pre-weaned calf performance of replacement beef heifers grazing summer forested meadows. {T. DelCurto and C.J. Mueller; in progress}<br /> Three experiments were conducted to evaluate the effect of amount (2 levels) and frequency of crude protein (CP) supplementation (daily, every 5 d, every 10 d) on ruminants consuming low-quality forage. The greater level of CP was estimated to meet ruminal requirements for degradable intake protein and the lower level was 50% of the greater level. {D. W. Bohnert, R. F. Cooke, S. J. Falck, B. I. Cappellozza, M. Van Emon, and C. S. Schauer}<br /> Determine the influence of supplement composition (energy- or protein-based) on steers (forage intake, nutrient digestibility, ruminal fermentation, and blood metabolites), beef cows (BW and body condition score change, calf birth weight, and blood metabolites), and replacement heifers (blood metabolites, growth rates, puberty attainment, and pregnancy rates).{D.H. Bohnert; in progress}<br /> Comparison of the effects of protein supplementation of cool and warm season low-quality forages consumed by beef cattle: differences in intake and digestibility. Projects will compare in-situ ruminal degradation of C3 and C4 forage; compare forage intake and nutrient utilization of ruminants offered low-quality C4 and C3 forage with and without CP supplementation; and obtain novel information for validation of intake and performance models. {D.H. Bohnert; in progress}<br /> UNIVERSITY OF WYOMING<br /> Studies have been conducted investigating strategic supplementation in ruminants, especially during gestation. (with North Dakota State University)<br /> USDA/ARS FORT KEOGH<br /> A series of studies have been conducted recently at Fort Keogh that has measured forage quality and measures of animal production. These measures can be used to compare how well the NRC predicts performance of cattle grazing rangelands in the Northern Great Plains.<br /> Recently published a paper demonstrating that intensity of historical management of a cow herd influences the importance of body condition at calving as a visual assessment of future reproductive success.<br /> Recently published paper demonstrating responses to supplemental methionine and cobalt in range cows<br /> Recently published 2 papers demonstrating that small amounts of supplemental protein supplied to wintering range cows can be used at a highly efficient rate to support same animal performance as higher amounts of protein supplementation.<br /> Assessing mineral intake and contribution to whole animal well being from self fed range mineral tubs<br /> Published a series of papers dealing with drought and subsequent influence on cow, heifer, and steer performance<br /> <br /> Objective 3. Disseminate and translate research-based management strategies to stakeholders for improving ruminant use in sustainable forage production systems.<br /> <br /> COLORADO STATE UNIVERSITY<br /> CSU has been working to develop a more effective forage program for the university cowherd at Fort Collins. In brief this effort centers around the following points:<br /> "Cows are on summer pasture off-site from June to November.<br /> "Focus of forage program is from December to May<br /> "Limited grazable forage at university farm<br /> "High costs of feeding harvested feeds<br /> "Irrigated land is available for intensive forage programs for Dec-May grazing options<br /> "Research-demonstration opportunity<br /> "Observations from New Zealand<br /> MONTANA STATE UNIVERSITY<br /> Six Extension presentations dealing with aspects of improving beef cattle use of forages and range livestock nutrition management were given to over 150 livestock producers, county Extension agents, and other interested parties.<br /> NEW MEXICO STATE UNIVERSITY<br /> Developed and implemented a monthly ranchers meeting titled Ranchers Roundtable at the newly completed NMSU Southwest Center for Rangeland Sustainability at the Corona Range and Livestock Research Center. The Ranchers Roundtable is designed to provide a comfortable atmosphere where ranchers ask questions regarding a particular topic to a panel of experts. Topics are timely and are scheduled approximately 3 months in advance of the rancher needing to implement information garnered. To date we have held 6 roundtables and have reached over 214 ranchers whom are responsible for over 20,000 cows.<br /> NORTH DAKOTA STATE UNIVERSITY<br /> Data has been published in multiple formats and made available for use by stakeholders. Data has also been presented at both regional and national meetings.<br /> OREGON STATE UNIVERSITY<br /> Tim DelCurto and Chad Mueller lead an industry-collaborated Cattlemens Workshop every January. This one-day event utilizes both industry and university speakers to discuss management strategies and current events that impact beef producers in the Intermountain West. Participants at the 2012 Workshop (n = 375) traveled from Oregon, Idaho, Washington, and Nevada. Dave Bohnert and Reinaldo Cooke started a forage-testing program (http://beefcattle.ans.oregonstate.edu/html/forage/Forage.htm) which includes analysis interpretation and supplementation recommendations.<br /> SOUTH DAKOTA STATE UNIVERSITY<br /> Evaluated interaction of weaning date (150 d vs. 210 d of age) with two post-weaning development treatments (drylot vs. rangeland) in 2 by 2 factorial treatment arrangement. Winter development programs influenced heifer growth patterns and reproductive performance. Further, winter development influenced patterns of range utilization. Day-of-sampling interactions indicated that range heifers did not adjust preferences and thus were already adapted to the range environment, whereas drylot heifers adjusted preferences over time suggesting they re-learned how to utilize the range environment.<br /> UNIVERSITY OF ARIZONA<br /> "In conjunction with Doug Tolleson, Dave Schafer, Bopper Cannon, and Keith Cannon of the University of Arizona V-V Ranch, Mike Sprinkle of Intel Corporation, Tyler DalMolin of the University of Arizona Department of Animal Sciences, and Bob Walker of Imperial Instruments, we obtained funding from Cargill Animal Health and successfully designed and evaluated the first ever high precision solar powered data acquisition system for obtaining individual mineral intakes by livestock in a rangeland setting. The equipment had ± 2 g resolution in pre-dawn hours when ambient conditions were constant and ± 17 g resolution when metal equipment was expanding during mid-morning, mid-day, and mid-afternoon. The SE for average range cow mineral intake was 14% of the mean in 2010 and 16% of the mean in 2011. For approximately $6,400, we developed a remote solar powered data acquisition system with low power draw components that provided reliable individual animal mineral intake in an extensive rangeland environment.<br /> "The Arizona Range Livestock Nutrition Committee presented a workshop Being a Range Cow is a Hard Way to Make a Living at Payson (50 people) and Willcox (24 people). I delivered a presentation on Managing Reproductive Stressors to Production: Nutritional and Physiological Bullets to Trigger Estrus Cycling and Enhance Fertility. In my presentation, I highlighted some of the recent work by NMSU and Mark Petersen with bypass protein. To make the connection with the audience I referred to it as the Atkins Diet for Beef Cattle. Participants rated the workshops (1 = not valuable, 5 = valuable) at 4.3 in Payson and 4.4 in Willcox.<br /> "Presented Reading the Range monitoring data on the NEPA Appeal for the Millsite Allotment at Superior to US Forest Service officials. The data presented helped resolve the appeal and enabled the permittee to increase the stocking rate in conjunction with monitoring data. The economic impact of that decision to the ranching operation was conservatively worth $24,819 per year.<br /> "Presented a talk on Range Livestock Mineral Research at the Arizona Section, Society for Range Management Summer Meeting at Mahan Park (75 people).<br /> "Presented a talk on Grazing Your Pasture at the Pasture Management Workshop for Landowners in Camp Verde (23 people).<br /> "Assisted a large ranch in Gila County with development of a nutritional management plan for the cow herd.

Brief Summary of Minutes

W1012 met in Las Cruces, NM on October 15 to 17, 2013 at New Mexico State University.

NIFA report:
Government is shut down and looking for a continuing resolution to operate. Two different farm bills have been passed. One eliminated the food program. It will go to conference committee. The AFRI program is in deficit and the call this year may be for the next two years.

Administrative Advisor report (Bret Hess):
Impact statements are being developed. It is important that reports are filed for these impact statements. They are used heavily in Washington. This years report should include not only this year but also summarize the 5 years. The committee did not meet in FY 2013 so we need to document activities the last year. The renewal will be discussed later in the meeting. The fund balance for the committee is $14,864.61.

Discussion of progress toward project objectives:

Objective 1. Validation of the utility and repeatability of the alkane assay for measuring fecal output by grazing ruminant animal.
Samples have been received by NM lab from Ron Lewis (VT) to evaluate the assay. Richard Waterman (USDA/ARS) is starting to work on the analysis. Ten test diets are being evaluated. Four locations at testing VT, USDA-ARS, Fort Keogh, NMSU. Two technicians per lab and two runs per technician. Three pure diets and defined mixtures of the three pure diets for a total of 10 diets.

Ron Lewis discussed some of the challenges with the assay and the across lab validation. Smooth brome and switch grass are similar enough in alkane analysis to create problems. Red clover C29 alkane is so high that it over whelms the calculations for diet composition. Diagnostic Bi-plot separation can help tell the plants apart. Size of grind may be an issue for warm season grasses. We may need to develop standard samples and training procedures. The tool works and there is some error as expected. Predictions do not predict the presence of a forage if it is not present. We may also need to add in more markers (alcohols). We could also use nutrient content to help the analysis.

The four sets of data will be combined an analyzed in the next year. This more complex than anticipated but progress is being made toward the objective. Progress is being made on the technique.

We need to evaluate the additions of external markers (i.e. beeswax). VT is doing alcohols, NM is doing beeswax and titanium, WY has a metabolism experiment (metabolism and duedonal for flow comparisons) comparing titanium and beeswax with FT Keogh. These samples will be used to evaluate animal intake.

Objective 2 Identify the shortcomings of the 1996/2000 beef NRC for cows grazing in Western rangeland environments.
The group presented a symposium at the JAM 2013 in Indianapolis IN on July 8-12, 2013. It was a joint annual meeting of the ADSA-AMPA-ASAS-CSAS dealing with research and current issues in animal science. The symposium was well received and made the information available to the NRC committee.

The two presentations have been prepared for publication as review papers and comments are back from the reviewers. The third is being prepared for submission.

A member of this committee (Joel Caton) is part of the NRC and will share the information papers with the NRC committee.

Station reports:
Each station gave a brief update of ongoing research and future plans. The station reports are incorporated into the annual report.

Project renewal:
After reviewing the options for renewal, the committee decided to pursue a W renewal. Shana Ivey will be the chair of the writing committee. Other committee members include Ken Olson, Eric Scholljegerdes, Ron Lewis, and Rachel Endecott.

Next meeting will be the day prior to the Western Section ASAS meeting On June 24.

Chad Mueller will be the next secretary and Dan Faulkner will move up to the chair position.

Grazing nutrition conference was discussed. The suggested steering committee will be Jack Whittier (chair), Mark Peterson (historian) , Richard Waterman (sponsorship), Eric Scholljegerdes (editor), Ken Olson (site coordinator), and Joel Caton (grants coordinator).

Accomplishments

Accomplishments<br /> <br /> Objective 1 <br /> Virginia Tech (Ron Lewis) validate the utility and repeatability of the alkane assay for measuring fecal output by grazing ruminant animal. <br /> <br /> A validated n-alkane method is available for validation across laboratories in multiple states. A thesis has been completed and 3 abstracts have been presented as a result of the validation of the n-alkane method. (Milestone 2010 and 2013)<br /> <br /> By combining n-alkanes and long chain alcohols as plant-wax markers, the botanical composition of mixed diets varying in their fescue and red clover contents could be even more reliably predicted. Furthermore, using multivariate statistical analyses (principal components), the information value of individual markers to distinguish plants could be characterized. <br /> <br /> Two studies have been conducted using supplements treated with beeswax that were fed to cattle. In these studies actual feed intakes were measured and fecal output was estimated using a either titanium dioxide or chromium-EDTA. These two markers are commonly used and will allow the validation of n-alkanes as an alternative. (Milestone 2012)<br /> <br /> Ken Olson at SDSU submitted a grant proposal that was funded dealing with supplementation of range cows. In this study he will dose beeswax with the supplement and the animals will be fitted with fecal bags for validation of beeswax as an estimator of supplement intake. (Milestone 2012, 2011)<br /> <br /> In a collaboration of Virginia Tech, New Mexico State University, USDA-ARS (Fort Keogh), and CSIRO (Canberra, ACT, Australia), laboratory protocols were shared, and defined mixtures of Smooth Broome and Switchgrass (collected at the U.S. Meat Animal Research Center, Clay Center, Nebraska) and red clover (collected at the Shenandoah Valley Agricultural Research and Extension Center, Raphine, Virginia) were distributed, for a blind across-lab validation study. The laboratory analyses of these sample are underway.<br /> <br /> A portable Calan Broadbent Feeding System was built to administer plant-wax markers to individual cattle at pasture via their addition to a small quantity of feed supplement. Through the construct of the supplement  inclusion of cracked corn or rolled oats mixed with color dyes  fecal samples could also be connected to individual animals without need for their physical restraint. <br /> <br /> Objective 2<br /> The group presented a symposium at the JAM 2013 in Indianapolis IN on July 8-12, 2013. It was a joint annual meeting of the ADSA-AMPA-ASAS-CSAS dealing with research and current issues in animal science. The symposium was well received and made the information available to the NRC committee.<br /> <br /> The two presentations have been prepared for publication as review papers and comments are back from the reviewers. The third is being prepared for submission.<br /> <br /> A member of this committee (Joel Caton) is part of the NRC and will share the information papers with the NRC committee<br /> <br /> 5th Grazing Livestock Nutrition Conference will be held in conjunction with JAM 2015. When the host city for JAM 2015 is identified then a venue will be chosen for this conference. (Milestone 2014)<br /> <br /> Objective 3: The members of W-1012 have published the following in 2012-13:<br /> 47 Referred journal articles<br /> 23 Abstracts and proceedings<br /> 10 Popular press articles<br /> 32 Extension bulletins and revisions<br /> <br /> Objective 4<br /> A total of 28 graduate and undergraduate students have been advised and/or mentored by members of W-1012.<br /> <br /> Approximately 300 high school youth have participated in youth camps and field days<br /> <br /> Four ration balancing software trainings were conducted for 23 Montana State University Extension Agents<br /> <br /> Extension programs have reached over 2200 producers representing over 50% of the cowherd in New Mexico, Montana, and Arizona

Impact Statements

1. Nutritionists and practitioners will gain a better understanding of the shortcomings of the current NRC Beef Nutrition manual as a result of publishing 3 refereed publications addressing changes needed to the NRC to appropriately feed cattle on western rangelands. These publications are projected to be used by the new NRC committee as they develop the latest NRC revision. More accurate NRC models will lead to more optimal production practices.
