What opportunities for training and professional development has the project provided?The NANP is filling critical gaps in training and professional development through the delivery of programs and resources in support of animal nutrition research. Collectively the modeling workshops held during the American Dairy Science Association alone have reached over 270 participants from 5 continents, most of whom self-identified as having less than 2 years of prior modeling experience. Collectively the modeling workshops held over the last 4 years of this project have reached nearly 750 participants. Additionally, workshop materials have been viewed more than 3000 times on public websites including NANP. These workshops are reaching broad audiences and training the next generation of animal nutrition scientists in the modeling skills needed to accurately evaluate diets and predict excretion of nutrients to the environment. Given the demographics of both workshop attendees (roughly half of whom identify as students or post-docs) and website usage, we similarly believe these events have helped NANP reach the next generation of scientists as is reflected in website user demographics. Specifically, significant training and professional development was offered via: An all-day modeling workshop was held during the 2017 American Dairy Science Association (ADSA) meeting in Pittsburg, PA. The workshop provided hands-on experience with several modeling approaches. The workshop's maximum capacity of 100 attendees was met with a waiting list of more than 10 others desiring to participate. Costs of the workshop were offset by a modest registration fee, the inclusion of which, obviously, did not negatively impact attendance. Over half of the participants completed an evaluation survey, the result of which was used to design future workshops. Respondents indicated a mean satisfaction rating of 8 on a 10-point scale. NANP participants were awarded a NIFA grant entitled "The NANP Nutrition Models Workshop: Training a New Generation of Scientists in Mathematical Modeling" of $40,878 (award #2019-67015-298411) to continue holding modeling workshops at the ADSA annual meetings for an additional 2 years. Following the successful workshop launce at the ADSA meetings, a modeling symposium was held in 2018 at the joint American Society of Animal Science (ASAS) and Canadian Society of Animal Science (CSAS) meeting in Vancouver, BC. This was followed in 2019 by a hands-on modeling workshop at the ASAS meeting in 2019. The model of an introductory symposium followed by hand-on training activities has been followed also at the Poultry Science Association (PSA) and the Equine Science Society (ESS) meetings. Despite the challenges presented by the COVID-19 pandemic in 2020 that prevented face-to-face professional society meetings, the NANP had a virtual presence at the 2020 American Society of Animal Science (ASAS) and American Dairy Science Association (ADSA) meetings where the Modeling Committee planned and held two virtual workshops: "2020 NANP Nutrition Models Workshop", June 21, 2020; ADSA Annual Meeting (38 attendees) "2020 ASAS-NANP Symposium: Mathematical Modeling in Animal Nutrition: Training the Future Generation in Data and Predictive Analytics for a Sustainable Development", July 19, 2020; ASAS Annual Meeting (100 attendees). Presentations and other materials from the following workshops and symposia held during the reporting period can be found on the NANP website. The NANP Symposium at the 2019 Symposium of the Equine Science Society: "Future Application of Models to Predict Nutrient Requirements: Outlook on Equids". Asheville, North Carolina. 200 attendees. The NANP Symposium at the 2019 Annual Meeting Poultry Science Association: "Future of Data Analytics: Development and Application of Models and Decision Support Systems for Poultry Nutrition and Production". Montréal, Québec. 200 attendees. NANP funds were leveraged with $5500 in industry support. The NANP Symposium: "Ruminant/Nonruminant Feed Composition" at the 2019 ASAS-CSAS Annual Meeting. Austin, TX. 40 attendees. The NANP Nutrition Models Workshop at the 2019 ASAS-CSAS Annual Meeting. "2019 NANP Workshop: Mathematical Model Building and Evaluation, and Data Analyses". Austin, TX. 66 attendees. The NANP Nutrition Models Workshop at the 2019 ADSA Annual Meeting. 2019 National Animal Nutrition Program (NANP) Workshop. Cincinnati, Ohio. 71 attendees from 11 countries. This workshop was supported through a NIFA grant. How have the results been disseminated to communities of interest?Results have been disseminated through peer-reviewed manuscripts, symposia and workshops at various profesional animal science society meetings. Further, trade booths were set up at multiple society meetings in multiple years to demonstrate changes in the program website and to allow individuals to participate in a hands-on, guided navigation of the website. What do you plan to do during the next reporting period to accomplish the goals?

What was accomplished under these goals?
Accomplishments can be grouped into 3 major categories. NANP website (www.animalnutrition.org) - Addresses Goals 1, 3, 4, 5, 7 The new site is a robust, mobile-friendly, easily navigable resource that provides for better user navigation and interface while allowing for faster content updates with many of the changes targeted for younger professional stakeholders who are capable with, and demanding of, state-of-the-art technological advancements and who will identify, address, and develop solutions for animal nutrition issues in the coming decades. Major accomplishments include: Completed the feed composition database for the upcoming NASEM Nutrient Requirements of Dairy Cattle report. Developed a single feed ingredient database for all species (rather than separate databases for each species). The total database can be filtered by a number is user-defined criteria. Expanded the database content to include equids. Updated all feedstuff definitions for improved clarity, created video tutorials for users of the database. Established a GitHub repository to foster sharing of computer code among the NANP modeling community. Worked with Elsevier to improve the utility of data they provided for the Global Animal Nutrition Expert Network (GANN; a second website database developed by the NANP program); search terms were developed and provided to ensure better capture of relevant literature and expert contacts. Education - Addresses Goals 2, 3, 4, 6, 7 Major accomplishments relative to education include: An all-day modeling workshop was held during the 2017 American Dairy Science Association (ADSA) meeting. NANP participants were awarded a NIFA grant to continue holding modeling workshops at ADSA annual meetings for an additional 2 years. A modeling symposium was held at the 2018 joint American Society of Animal Science (ASAS) and Canadian Society of Animal Science (CSAS) meeting. This was followed by a hands-on modeling workshop at the ASAS meeting in 2019. The model of an introductory symposium followed by hands-on training activities has been followed also at the Poultry Science Association (PSA) and the Equine Science Society (ESS) meetings. Despite the challenges presented by the COVID-19 pandemic in 2020, the NANP had a virtual presence at the 2020 ASAS and ADSA meetings where the Modeling Committee planned and held two virtual workshops. In addition to the education efforts directed at stakeholders directly involved in animal nutrition research or feeding of animals, the second NANP National Summit entitled "Producing Food with Animals: Sustainability, Efficiency and Security in the U.S." was held in 2019 at the National Academy of Science building in Washington, DC. The summit was a forum to discuss and identify research priorities, focusing on the specific role animal nutrition research plays in addressing animal production sustainability (both environment and economic) and security. The summit engaged stakeholders from federal research and regulatory agencies as well as industry. Marketing and communication efforts resulted in the creation of a new brand strategy and logo for NANP along with accompanying educational and promotional materials for distribution at national and international meetings/workshops. National Academy of Science, Engineering and Medicine (NASEM) - Addresses Goal 1 NASEM is responsible for periodic updates to the nutritional requirement estimates for the various animal species. These publications are the international standards in animal nutrition, being cited in the vast majority of peer-reviewed research publications as the starting point for that research and being used as the starting point by industry nutritionists before adjustments are made based on unique environment or genetic needs that they are feeding. NANP created an extensive feed composition database as well as modeling resources for the nutrient requirement update committees for beef (released in 2016), dairy (to be released spring 2021) and poultry (soon to be sent to external reviewers; perhaps published in 2022). In addition to these resources, the Coordinating Committee for the program has provided lists of potential members for populating the revision committees and of individuals who might serve as outside reviewers for the drafts of the revisions. Impacts NANP website (www.animalnutrition.org) - Addresses Goals 1, 3, 4, 5, 7 Over the current project period, NANP has collected, screened, sorted, and archived over 4 million records of feed composition information. Methods for automating the screening of feed composition data based on machine learning techniques (decision tree, random forest, gradient boosting, and neural networks) that will be able to automatically classify new feed datasets, resulting in improvements in research efficiencies across the discipline. NANP website usage increased substantially since the overhaul. The current site has an increasing use trajectory. Website analytics show a year-to-date 15% increase in total sessions and 47% increase in nutrient requirement model usage in 2020 over 2019. In addition, more than 24,000 individual ingredient searches have been performed by users since the revamped database launched in July 2019. As of August 2020, there were nearly 350 registered users. Access of the website by users from over 65 countries has occurred. There was also a nearly two-fold increase in users in the 18-24 years of age category, demonstrating success in our efforts to reach the next generation of animal scientists. Education - Addresses Goals 2, 3, 4, 6, 7 Collectively the modeling workshops held during the American Dairy Science Association alone have reached over 270 participants from 5 continents, most of whom self-identified as having less than 2 years of prior modeling experience. Collectively the modeling workshops held over the last 4 years of this project have reached nearly 750 participants. Additionally, workshop materials have been viewed more than 3000 times on public websites including NANP. These workshops are reaching broad audiences and training the next generation of animal nutrition scientists in the modeling skills needed to accurately evaluate diets and predict excretion of nutrients to the environment. Given the demographics of both workshop attendees (roughly half of whom identify as students or post-docs) and website usage, we similarly believe these events have helped NANP reach the next generation of scientists as is reflected in website user demographics. Publications - Addresses Goals 2, 3, 4, 6 The NANP published a total of 14 peer-reviewed journal articles as direct outputs of the NANP committee and postdoctoral activities that include new methods of feedstuff evaluation (data mining, sorting, categorizing, and defining), workshop presentation publications, and position papers. Additionally, numerous abstracts associated with professional society presentations were published. In addition to publications previously reported on the roles of animal nutrition research on greenhouse gas emissions and global maternal and child health, NANP enabled the development of two new publications in 2020 advancing assessments of water use and overall sustainability of animal production. Both publications are creating tools for assessing environmental impact in aid of policy and decision-making. There are other strong evidences that the NANP is being recognized as the premiere animal nutrition resource it was intended to be. The UN Climate Change program's NDC Partnership will use feed ingredient information from NANP as part of its Holos whole-farm model for estimating greenhouse gas emissions. BASF is aligning its application for least-cost animal feed formulations to be consistent with the feed names and definitions used by NANP. It is clear that through these partnerships and the usage statistics for the NANP website, the NANP is seen as a leading force in animal nutrition research.

Target Audience:The primary audience for NANP is the animal science research community including members of NRC (NASEM) revision committees (beef, dairy, and poultry), as well as NASEM staff and feed and animal nutrition industry representatives. Changes/Problems:
Nothing Reported
What opportunities for training and professional development has the project provided?Two modeling workshops were held at the ASAS and ADSA annual meetings to provide training opportunities on the use of animal nutrient utilization models for student, researchers and industry. How have the results been disseminated to communities of interest?Results have been disseminated through peer-reviewed manuscripts, the national summit, symposia and workshops at various profesional animal science society meetings. Further, trade booths were set up at multiple society meetings in multiple years to demonstrate changes in the program website and to allow individuals to participate in a hands-on, guided navigation of the website. What do you plan to do during the next reporting period to accomplish the goals?We will continue to work with NASEM in support of the dairy and poultry updates as well as conitnue refining the tools available through the NANP website.
Impacts
What was accomplished under these goals?
The Coordinating Committee efforts included the planning and implementation of the second NANP National Summit and preparing for the renewal of the NRSP9 proposal. The Feed Composition and Modeling committees continued their work in populating the website with expanded data and improving functionality for end users. The groups also continued to focus on meeting stakeholder needs and improving the utility of the tools being developed through the delivery of symposia and workshops. The NANP continued to serve key roles in the updates to the National Academy of Science, Engineering and Medicine's Animal Nutrition Committee, creating feed composition and modeling resources for the active update committees for both dairy and poultry. Major accomplishments toward meeting the project's objectives and anticipated outcomes include: The capabilities for the feedstuffs database were expanded to include filters to: 1) transform nutritional information from a 'dry matter'(default) to an 'as fed' basis, 2) select nutrient composition from feedstuffs that were analyzed in a specified range of years, 3) select nutrient composition according different types of data sources [peer-reviewed (data obtained from scientific journals), commercial (data obtained from commercial laboratories), and academic (data obtained from academic laboratories that has not been published)], and 4) select specific nutrient values using multiple custom options. In support of the NASEM "Nutrient Requirements of Poultry, 10th Edition" a dataset for the poultry feed composition tables was created using feed composition information obtained by literature reviews using the methods previously followed for the existing swine feed composition tables. The poultry tables were updated with feed composition information available in scientific articles published between 2011 and 2018. The dataset was screened using a univariate procedure which deleted values above and below 3.5 standard deviations (SD) from the average for each nutrient. The final dataset and tables contained more than 4,000 feed samples comprising 131 ingredients and 91 nutrients. The Modeling Committee also contributed to the NASEM Poultry publication update. An existing poultry growth model was transcribed from Excel to R and will be used by the Poultry Committee to revise nutrient requirements for growth after it is fitted to the data. The expansion of NANP content to include equids started with the completion of the mining of literature for data on nitrogen and amino acid nutrition and metabolism. A conceptual model for prediction of N requirement and excretion in equids was developed and published (see publications for citation). NANP participants were awarded a NIFA grant titled "The NANP Nutrition Models Workshop: Training a New Generation of Scientists in Mathematical Modeling of $40,878 (award #2019-67015-298411) to continue holding modeling workshops at the ADSA annual meetings for an additional 2 years. The second NANP National Summit "Producing Food with Animals: Sustainability, Efficiency and Security in the U.S." was held on April 10, 2019 at the National Academy of Science building in Washington, DC. Like the inaugural NANP summit held in 2015, the program created a forum to discuss and identify research priorities, focusing on the specific role animal nutrition research plays in addressing animal production sustainability (both environment and economic) and security. The summit engaged stakeholders from federal research and regulatory agencies as well as industry. There is strong evidence that the NANP is being recognized as the premiere animal nutrition resources it was intended to be. The NASEM Poultry revision will use NANP as the primary source of feed ingredient information for its audience, including only a small subset of 12 ingredients in the static printed report. The UN Climate Change program's NDC Partnership will use feed ingredient information from NANP as part of its Holos whole-farm model for estimating greenhouse gas emissions. BASF is aligning its application for least-cost animal feed formulations to be consistent with the feed names and definitions used by NANP. It is clear that through these partnerships and the usage statistics for the NANP website that despite the challenges encountered during the website/database restructuring, the NANP is seen as a leading force in animal nutrition research.

Progress 10/01/17 to 09/30/18
Outputs
Target Audience:Discussion of the NANP activities has occurred with members of NRC revision committees (dairy and poultry), NASEM staff, members of theAnimal Nutrition subcommittee of the American Feed Industry Association, at industry nutrition conferences (e.g., MidwestSwine Nutrition Conference and Minnesota Nutrition Conference), and at academic multi-state committees (NCCC-042Committee on Swine Nutrition and the S1061 Nutritional Systems for Swine to Increase Reproductive Efficiency). The general animal nutrition academic community has been engaged through a symposium at the American Society of Animal Science meetings and through a workshop at the American Dairy Science Association meeting. Changes/Problems:Previous open postdoctoral positions hindered many activities. Both positions are now filled and the breadth and depth of activity has been markedly improved. What opportunities for training and professional development has the project provided?Asymposium at the American Society of Animal Science annual meeting in July 2018 introduced attendees to the potential of modeling in animal science. Aworkshop at the American Dairy Science Association meeting in June 2018 provided advanced training in actual modeling techniques after the introductory workshop in 2017. How have the results been disseminated to communities of interest?Results and opportunities have been made known through professional society communications. What do you plan to do during the next reporting period to accomplish the goals?Plans are to finish all web-based updates and revisions, continue to submit workshop proposals (both beginning and advanced) for funding for presentation at more professional society meetings, and publicize NRC revisionswhen they are released.
Impacts
What was accomplished under these goals?
Goal 1. The database was developed and utilized by the Committee on Dairy Cattle Nutrition. It will be used as a part of the publication that is released in 2019. Further, the Committee on Poultry Nutrition is considering using the database as a "living" resource rather than as a source of static feed ingredient tables. Goal 2. No specific activity. Goal 3. A proposal for a workshop on techniques was developed and submitted for consideration for the 2019 ASAS annual meeting. Goal 4. No specific activity. Goal 5. The network was established in previous years but there were limitations to its breadth. Limitations continue to be identified and resolved. New databases are being incorporated into the expert network that should meet original design expectations. Goal 6. No specific activity. Goal 7. The NANP website has been redesigned and submission capabilities are to be incorporated. Discussion of the best method for logging of the communications is in progress.
