Minutes of the Annual Meeting

August 8, 2016 (Business Meeting)

Ron Lewis opened the meeting with an expectation of the meeting and agenda.  He thanked all the Panhandle Research & Extension Center (PHREC) faculty and staff for their assistance and input in the program. He also thanked the Agricultural Research Division, Institute of Agriculture and Natural Resources, at the UNL for providing $1,000 in support of the costs of the meeting.

We were welcomed to the PHREC by Jack Whittier, station director, with a PowerPoint overview of the station and UN IANR, Nebraska/Panhandle agriculture, and associated programs/facilities.

The Business Meeting was called to order by Ron Lewis.

1)  Minutes from the 2015 meeting were approved

2)  Bret Hess

  a. Provided a budget overview. 

  b. OSU and MSU provided support for the GLNC – there are 2 outstanding.  Things are being finalized

  c.  NIMMS is new and if there are any issues please let your Ag Experiment Station know or contact Bret directly.  There is a process under “report a bug” on the NIMMS website to work on problems/issues

  d.  After the 3rd year of our project there will be a mid-project review.  We are well on track to meeting objectives.  We need to continue telling how the project is working in coordinated fashion to meet its objectives.  Participation of Appendix E is also a key component.  People need to provide reports – they may not be attending but they are participating by providing the report.

  e.  NIFA – funding for multistate projects.  It is an election year which means there will be changes in leadership.  Sonny Ramaswamy (director of NIFA) will not change for probably at least 3 yr.  Sonny has and will continue to push for competitive funds while also pushing for capacity lines.

  f.  Foundation for Food and Agricultural Research – a program that early/mid-career scientists need to consider for support dollars.

3)  Election of the Secretary Elect

  a. Jim Sprinkle was unanimously elected.  The 2018 meeting will be held in Idaho.  Jim will be in charge of the report and minutes for the 2017 meeting.

4)  Tim DelCurto suggested that an overview of the importance of the Regional/Multistate Projects be provided.  Bret Hess provided an overview:

  a.  Started in the 1940’s so that work in individual states could be more impactful if research and extension activities were coordinated across multiple states within the region.  These activities have evolved, primarily, into research projects like W2012.

  b.  Advantages for young scientists/graduate students includes networking, brainstorming ideas, etc.  Provides knowledge of what facilities/resources/expertise are around the region.

Ken Olson (via email)

Objective 1:

1) Collected samples (annual brome, western wheatgrass, sweet clover)

  a. Annual brome difficult due to drought and amount of material available

  b. Collection of warm season forages will need to start soon

     i. Little sideoats gramma (not enough for sample collection)

    ii.  In western High Plains blue gramma and buffalo grass typically grow comingled so it is impossible to separate these species; however, buffalograss could be collected from heavily grazed areas.

   iii.  Winter dormant samples could be a problem

      1.  Annual brome again will not be present in amounts available to collect

      2.  Yellow sweet clover will only be stems that livestock will not consume/select

   iv. Question: He needs direction as to whether collections of mixtures of these grasses will fulfill the objectives or whether he could switch to buffalo grass to get a single species.  Also, should he collect the stems of yellow sweet clover?  The consensus of the attendees was to collect the individual species that he could – if there is none to collect that is fine.  Also, the instructions for sample collection allowed for flexibility of collecting a unique species or two to that area/station; therefore, the buffalo grass should be fine.

Progress Toward Project Objectives

Objective 1: Assess variation across space and time for n-alkane composition in unique classes of forages common to the Western United States, which is necessary for predicting feed intakes and diet choices of grazing ruminant animals.

General

• Plans reviewed for collecting forage samples. Each research station will select a sampling date when forages will be at their peak vegetative and dormant At each sampling, the location and, where possible, soil properties will be recorded. Approximately 500 g of dry plant matter will be collected. About 100 g of each sample will be retained as the entire plant. The remainder will be subdivided into plant parts as appropriate (i.e., leaf, stem, flower, and seed head). These samples will be dried at 55 °C. Samples will then be ground through a 1 mm screen using a mill (Wiley Mill). Samples will then be stored at room temperature until analysis.
• The forages sampled will be:
  • Cool-season grasses (C3): Western Wheatgrass (Agropyron smithii), Cheatgrass (Bromus tectorum);
  • Warm-season grasses (C4): Blue grama (Bouteloua gracilis), sideoats grama (Bouteloua curtpendula);
  • Legume: Sweet Clover (Melilotus officinalis); and,
  • As many as two additional C3 and C4 grasses and a legume specific to a station

Ron Lewis

• In a second year of collections, 3 cool- and 3 warm-season grasses, and 2 legumes, were sampled at their peak vegetative and mature states at the West Central Research and Extension Center, North Platte, NE. Collection sites were primarily native mixed-grass rangeland within the rolling plains typical to West Central NE. Beyond the standard forages collected by all participating stations, needle-and-thread (C3), little bluestem (C4) and lead plant (legume) also were sampled.
• The robustness of the plant-wax method depends on consistently quantifying the plant-wax contents of plants. Three technicians in 2 labs measured the n-alkane concentrations of C27, C29, C31 and C33 in pure and 9 mixtures of tall fescue and red clover. Labs, and technicians within labs, differed in their quantification of the individual n-alkanes. However, within technician fescue contents of the mixtures were estimated reliably, although consistently high for 2 technicians.
• Delineating the composition of forage communities using plant waxes depends on the profiles of those markers being sufficiently distinct. The concentrations of 5 n-alkanes and 5 long chain alcohols were determined in 3 cool- and 3 warm-season grasses, and in 2 legumes, harvested at 2 phenologies (vegetative; mature). Cattle diets were simulated and their species composition estimated. At both phenologies, legumes were distinct from grasses, reflecting higher C29, C26-OH and C30-OH concentrations. Blue grama was unique in its C33 and C32-OH contents. However, the 8 plant species could not be clearly discriminated in these diets.

Utah State University

Earl Creech

• Advised 3 M.S. students (Rob Smith, Joseph Sager, and Craig Rigby) who completed projects evaluating the establishment, persistence, competitive ability, and production of a variety of forage plant materials on rangelands. Rob Smith’s research focused on the potential of forage kochia to establish and compete in rangelands dominated by the invasive weed halogeton. Joseph Sagers’ project built upon Smith’s work by characterizing forage kochia response to salinity. Craig Rigby conducted a study on rangeland sites across several western states to compare establishment, production, and persistence of different forage grass species and cultivars.

South Dakota State University

• South Dakota State University initiated the 3rd, two-year class of beefSD, an educational program for beginning beef producers. Fifty-two participants will interact with 19 peer mentors (alumni of past beefSD classes) to complete this program. beefSD is funded by a USDA Beginning Farmer and Rancher Development Program grant.
• Two classes of South Dakota Grazing School were conducted in 2016, with 61 individuals completing the course. Grazing school is a collaborative effort of SDSU Extension and the South Dakota Grassland Coalition.
• The 44th Range Beef Cow Symposium was held in November 2015. This was a joint effort of South Dakota State University, University of Nebraska, University of Wyoming, and Colorado State University, with CSU hosting the 2015 symposium. Participant registrations indicated presentations increased participant knowledge on most topics and virtually all participants intended to implement change in their operations based on the knowledge gained.

Research

• In the western US, especially in the Intermountain West regions, demand for new and suitable plant materials is a long-term issue and is increasing continuously. The objective of this study is to evaluate different advanced lines of C3 grasses with the inclusion of some local checks in relation to their growth, yield, and quality response to irrigation, drought, and planting time. Species used in this study include tall fescue (seven lines), tall wheatgrass (three lines), western wheatgrass (five lines), and wildrye (two lines). Fall planting was made in late August 2008 whereas spring planting was in early May 2009. Data collected on different growth parameters, persistence, and forage quality from 2009 - 2015 for both plantings seems to be different among species and lines. Long-term data collection will help select and develop superior and well-adapted cultivars for the region.

Washington State University

Donald Llewellyn

• Downy brome in rangeland is a significant problem in the grazing land of eastern Washington State. In addition, several generations of beef producers and grazing managers have unfortunately come to rely on downy brome as their primary early season pasture grass.  Our team in currently developing a multi-year project to address this situation.
• Our approach is to investigate a biological approach to manage downy brome in rangeland and to biologically encourage reestablishment of favorable bunchgrasses in extensive landscapes. Our team also plans to expand the project to production-scale acreage on producer-cooperator ranches.
• Our goals and potential impacts is to provide producers with recommendations on natural and sustainable downy brome control in rangeland, how to foster rejuvenation of highly productive naturally occurring bunchgrasses, and proper grazing management to sustain rangeland health and maximum productivity. We are also investigating feeding alternatives to take the place of downy brome as early season grazing.
• Our potential impacts will be driven by outcome-based demonstration and Extension programming focused on long-term productivity in rangeland. Producers will be educated and change grazing philosophies and attitudes about managing downy brome.  In doing so, rangeland will become more productive and grazing seasons will be lengthened, all adding to the economic sustainability of cow/calf and stocker grazing operations in the Pacific Northwest.

• Presented 7 invited talks on range livestock nutrition or range livestock research at 6 locations in Idaho to approximately 272 people. Additionally, presented a talk on Idaho range livestock nutrition research at the American Society of Animal Science (ASAS) in Salt Lake City. Presented 6 invited talks and 2 demonstrations on range management and range monitoring topics to approximately 280 people at 4 locations in Idaho and 2 locations in Wyoming. Three of these talks were at the Idaho Range Livestock Symposium and the three talks in Wyoming were in Sublette County at the invitation of the Wyoming Department of Agriculture.
• At the University of Idaho Nancy M. Cummings Research, Extension & Education Center, every replacement heifer is evaluated for residual food intake (RFI). These high and low RFI 2-yr-old cows are being evaluated while grazing a common rangeland. One grazing behavior and production efficiency research trial comparing these divergent cows on late season rangeland (non-lactating) was completed in 2015 in conjunction with the U. S. Sheep Experiment Station in Dubois and results were published in the Western Section, ASAS proceedings. Research is ongoing comparing lactating 2-yr-old cows on summer rangeland for forage intake using a pulse-dose alkane procedure; production efficiency (e.g., fertility, cow weight, and condition score); and grazing behavior using relatively inexpensive “homemade” GPS collars. Dr. Ron Lewis of the University of Nebraska-Lincoln is performing the alkane analyses for the pulse dose forage intake trials.
• In conjunction with 7 Extension Educators in Idaho, determining mineral status in nine counties in Idaho for both irrigated and rangeland forages during peak growing and dormancy seasons.

Mr. Vargas Jurado’s presentations focused on his development of computational methods (a Bayesian hierarchical model) to more reliably predict dietary choices and feed intakes in grazing herbivores using plant-wax markers. This work was a collaboration between the Animal Science and Statistics Departments at the University of Nebraska-Lincoln.
• In a collaboration with the U.S. Meat Animal Research Center, Emily Hilburger, an MS student, and Ashley Buescher, an undergraduate student, were involved in the second year of experiments testing the utility of using plant-wax markers to predict dietary choices and intakes in cattle in controlled (pen) and in grazing conditions. Beyond field work, this effort involved their developing the requisite laboratory skills (e.g., gas chromatography) to analyze the plant-wax contents of the plant and fecal samples collected. Ms. Buescher’s involvement was as a summer internship in the Engler Agribusiness Enterprise Program at the University of Nebraska-Lincoln.

Accomplishments Related to Project Objectives

Objective 1:

• A key factor for predicting feed intakes and diet choices of grazing ruminant animals in the Western United States is assessing variation across space and time in the n-alkane composition of unique classes of forages common across this region. Protocols for collecting and storing forage samples on cool (C3) and warm (C4) plants, and on legumes, were agreed. Where possible, environmental measures (e.g., elevation; soil description; precipitation) corresponding with the plant sampling will be recorded.
• Across-lab consistency in measurement of the n-alkane contents of samples, both plant and fecal, is central to the reliability and general applicability of the plant-wax marker methodology. Analyses of defined mixtures of forages has been evaluated in a ‘blind’ across-lab validation study. The laboratory analyses of those samples were still underway but an outcome of that effort will be establishment of consistent procedures for routine evaluation of n-alkanes among a network of labs.

Objective 2:

• Ron Lewis, Mitch Stephenson, and Jack Whittier received a 1-year duration (August 2016 – August 2017) grant from the Agricultural Research Division, Institute of Agriculture and Natural Resources, University of Nebraska-Lincoln, Strategic (Miscellaneous) Funding Source to support the W2012 Multistate Hatch Project Annual Meeting. Amount: $1,000.

• Research with selection for well-adapted forages has contributed to the improvement of productivity of local and regional producers.

• Research has been initiated evaluating the utility of using pulse dose (single low dose) alkanes for rangeland applications to determine individual forage intake.

Objective 3:

• Grazing Lands Nutrition Conference: The 5th GLNC was held July 17-19, 2016, at the Canyon Resorts, Park City, UT. There were 139 registered attendees. The Conference was organized by a sub-committee of the W2012 project group, with many group members actively participating in the event. There were 18 invited speakers (of which two were invited posters presenters) and there are 12 proceedings currently in press.
  • Sponsors of GLNC included
    • USDA NIFA (Conference Grant; award number 2016-67016-24864)
    • Corporate sponsors including Micronutrients and Novus
    • The Agricultural Experiment Stations of Montana State University and Oregon State University
    • The Western Section of the American Society of Animal Science provided financial support
    • The National Office of American Society of Animal Science provided logistical support.
  • Through engagement of 45 graduate and undergraduate students in research activities underway within this Multistate Research Project, young scientists have been provided opportunities to develop skills in the design and conduct of successful research programs, and experience with publication and grantsmanship.
  • Through participation in regional and statewide meetings, workshops and short courses, expertise in extensive livestock systems across the Multistate Project team was leveraged to impact ranching and farming practices throughout the Western region.

What two aspects of the conference – be they the venue, organization, or content – contributed the most to your learning and/or own research, extension and teaching program?

                   Aspect one:

1. Bringing of people from all over the world provided direct interaction and learning that cannot be duplicated via email/phone
2. Venue: liked tables in the conference rooms
3. More appreciation of role of rumen microbiome
4. The quality of presentations were solid – speakers were allowed to speak about topics without being confined to research design
5. Content of presentations
6. Well-spoken speakers
7. Very good topics and good discussion of those topics
8. The combination of research and applied practice, worldwide knowledge and impact were refreshing and displayed the real importance of our work and continuing research
9. Plenary presentation (Galyean) providing a holistic discussion of trials and tribulations of evaluating feed intake in grazing system.
   
   Aspect two:

1. The theme/content and the ability to overlap and show potential research areas around the various topics.  The diversity of speakers/topics around a common them.
2. Content: Presenters flowed well from one to the other
3. Synthesis of several of range/nutrition topics for holistic viewpoint
4. Content of posters
5. Very beautiful venue
6. Park City was a good location, always a good conference venue
7. Enjoyed the venue and time for socialization and networking
8. Discussion f role of microbiome in defining feed efficiency (Guan)

What one aspect of the conference – again be it the venue, organization, or content – would you suggest be changed to better contribute to your learning and/or own research, extension and teaching program?

1. Potential to interact with both industry and academics – maybe a tradeshow/booth area to congregate and talk about projects/research
2. Better organization
3. Add panel discussions to encourage more interaction by attendees
4. More discussion of grazing animal research.  Current and future efforts and needs
5. Less intensive schedule
