Brief Summary of Minutes of Annual Meeting

The meeting was hosted by Dr. Sprinkle in Salmon, ID. The two main business items discussed were submission of the annual/final report and the project renewal. Dr. Dr. DelCurto was elected to prepare the report and Dr. Sprinkle agreed to take the lead for drafting the project renewal.

 Objectives: 

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. 

• Include information regarding samples collected. Specifically:

• 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)
• As many as two additional C3 and C4 grasses and a legume specific to a station 

2. Coordinate research and extension activities in extensive livestock production systems. 

• Include face to face presentation as well as extension publications, and internet publications including Facebook pages with number of “likes”
• Be sure to include approximate numbers of attendees at events because we need to be able to quantify impacts. It is much more powerful to say presented at an event with 30 people representing 60% of the cows in Arizona rather than I presented at an event. 

3. Provide professional development and mentoring opportunities for committee participants, young scientists, stakeholders, and graduate students. 

• Include graduate, undergraduate and high school students
• Need to include names, degrees sought and title of thesis/dissertation
• Include “Train the trainer” events with number attending 

Our project Milestones are: 

• (2014): Work toward standardization of n-alkane procedures across states. Collect plants from participating states. Develop plan for 5th Grazing Livestock Nutrition Conference.
• (2015): Summarize and prepare scientific publication on regional and phenological variation of n-alkane profile of common rangeland plants.
• (2016): Organize and hold the 5^th Grazing Lands Nutrition Conference along with publication of proceedings papers.
• (2017): Identify the strengths and shortcomings of the current Nutrient Requirements of Beef Cattle based on research results obtained from experiments conducted by this Multistate Research Project. Begin planning the 6th Grazing Livestock Nutrition Conference. Begin addressing areas of interest for project renewal.
• (2018): Prepare Project Renewal that addresses “Optimizing and Characterizing Sustainable Beef Cattle Production in Forage Based Systems on Western Rangelands.”

The activities, outputs and short-term outcomes of the previous 5 year period of this project are summarized below: 

• The work focused on standardization of n-alkane procedures across states was successful with University of Nebraska, Lincoln and New Mexico State University doing the highest degree of collaboration with n-alkane laboratory procedures.
  • Most universities participated with the forage sampling protocol
• The new NRC 2016 Nutrient Requirements of Beef Cattle verified the need for research into the shortcomings for predicting intake. We will continue to refine and update estimating forage intake on rangeland.
• Successfully organized and executed the 5^th Grazing Livestock Nutrition Conference held July 17-19, 2016 at the Canyon Resorts in Park City, Utah. There were 18 invited speakers and 21 volunteered posters for this symposium and 139 individuals from around the world attended. Sponsors of GLNC included USDA NIFA (Conference Grant; award number 2016-67016-24864), corporate sponsors including Micronutrients and Novus, and the Agriculture Experiment Stations of Montana State University and Oregon State University. In addition, the Western Section of the American Society of Animal Science provided financial support and the National Office of American Society of Animal Science provided logistical support.
• The list of research achievements, publications, and student theses that are the product of the collaborative work of members of the Project is extensive. From 2013-2018, approximately 130 refereed publications, 64 proceedings, 78 technical bulletins, 8 book chapters, 60 popular press articles, and 106 abstracts have resulted.
• Since 2015, our members have participated extensively in and gave presentations each year at extension meetings, nutrition conferences, professional society sponsored national and regional meetings, and annual W-2012 meetings to promote the exchange of ideas, information and data. Three members of W-2012 organized the first ever nationwide Grazing Behavior In-Service preceding the Society for Range Management national meeting in 2017.
