Final Report for EW03-003
The Feed Management education project held ten workshops in Washington, Idaho, and Oregon that focused on Feed Management for audiences at the introductory or advanced level. The primary livestock audiences were dairy and beef. During the latter part of 2004 we developed a tool to implement the concept of Feed Management on dairy operations. The development of this tool led us to submit a grant proposal to the NRCS Conservation Innovation Grant Program. In September of 2006, we were awarded a $425,000 grant from NRCS to develop and implement Feed Management nationally according to NRCS Practice Standard 592 – Feed Management.
- 1. Provide training to Ag Professionals in feed management concepts and practices that minimize the import of nutrients to the farm and provide economic and environmental sustainability
2. Provide training in the use of computer models and software for strategic ration balancing, whole-farm nutrient balance, and whole-farm economics
3. Develop educational materials that are specific to the Pacific Northwest regional animal industries while utilizing national curriculum developed to address nutrition in the context of nutrient management
The U.S. Environmental Protection Agency (EPA) released new guidelines for Concentrated Animal Feeding Operations and Animal Feeding Operations (CAFO/AFO) in early 2003. Under the new guidelines, CAFO/AFOs will be required to develop a Nutrient Management Plan (NMP). One of the NMPs is a Comprehensive NMP as defined in the Natural Resources Conservation Service (NRCS) National Planning Procedures Handbook (http://www.nrcs.usda.gov/programs/afo/cnmp_guide_600.54.html). There are six components of a CNMP: 1) Feed Management, 2) Manure and Wastewater Handling and Storage, 3) Nutrient Management, 4) Land Treatment, 5) Record Keeping, and 6) Other Manure and Wastewater Utilization Options. The Nutrient Management element of a CNMP contains nine components. Nutrient Management Plans have been developed for most of the dairies in WA, OR, and ID, however, the Feed Management component of a CNMP is not part of Nutrient Management Plans in the region. Few other livestock operations (beef, swine, and poultry) in the region have been required to have or have voluntarily adopted Nutrient Management Plans.
Once the new EPA guidelines are adopted and implemented in each state, any livestock or poultry operation which chooses to develop a CNMP, will have an immediate need for an understanding of the Feed Management component of the CNMP. The NRCS has developed one-page facts sheets as an introduction to Feeding Management, but the EPA has no plans for an educational program beyond the fact sheets. The education project in the current proposal will provide needed training for staff of NRCS, Conservation Districts, Nutrient Management Consultants, Nutrition-Management Consultants, and designated Nutrient Management Specialists of large animal operations.
Although NRCS and Conservation District (CD) staff are trained in most components of a CNMP, they have little or no educational background in Feed Management. Nutrient Management consultants also need training in the Nutrition Management of a CNMP. Whereas Nutrition Management consultants have been trained in diet formulation and ingredient management, they are, in some cases, not aware of the most recent information about the environmental and economic merits of the newest technologies. In order to have the greatest impact in the region it is important to reach these professionals who will serve and influence the livestock and poultry producers.
Feed represents the largest import of nutrients to the farm, followed by commercial fertilizer (CAST Issue Paper # 21 – Animal Diet Modification to Decrease the Potential for Nitrogen and Phosphorus Pollution -http://www.cast-science.org/castpubs.htm#animaldietmodif). Feeding Management opportunities currently exist to reduce imports of nutrients, particularly nitrogen and phosphorus, to most animal and livestock operations. The technologies and approaches to achieve these reductions vary in their degree of economic feasibility and environmental impact. It is important that agricultural professionals understand the degree of success that can be expected both from and economic and an environmental standpoint.
Education & Outreach Initiatives
A combination of educational approaches was used during the project and included: workshops, field days, case studies, and computer software training. In addition, fact sheets and presentations from workshops were made available on a website (http://www.puyallup.wsu.edu/dairy/joeharrison/).
A module system of education blocks were developed that were tailored to the participant’s previously defined understanding of nutrition and feeding management. This module system included “Feed Management 101” for the participant that wanted to be able to converse about feed management but not be actively making on-farm recommendations. Advanced modules (201 level) addressed applications of feed management strategies with case studies. In addition, the option to receive training in the use of computer models and software for strategic ration balancing, whole farm nutrient balance, and whole-farm economic analysis was provided.
The Livestock Poultry Environmental Stewardship curriculum (http://www.LPES.org) served as base education materials and was with supplemented by University specialists from the region. Additional topics identified by the regional University specialists were: specialty feed ingredients (enzymes, amino acids, organic vs inorganic minerals), and outside sources of minerals (copper in copper-sulfate footbaths). Specific software/computer models that were identified and training provided were: Cornell -Penn-Miner (CPM) ration balancing model, DAFOSYM (model for whole-farm nutrient and economic analyses), whole-farm balance nutrient education tool (WFBNET), and AminoCow.
To accommodate the needs in the three-state region, we held 10 workshops over two years. We found that our greatest success was to partner with Allied Ag industry for meeting topics and advertising and when possible hold workshops in conjunction with other conferences in the region such as the Pacific Northwest Animal Nutrition Conference.
We were able to organize one field day in 2004 in cooperation with a county-based conservation district. This event was well attended (~77 people) and evaluations were very positive about its impact to provide valuable education.

In 2002 we envisioned a Feed Management Education Program that focused on increasing the understanding of the positive environmental and economic role that feed management can play in livestock operations. This overall vision was achieved during the two-year project. During late 2004 we developed a draft tool that we thought would facilitate the adoption of Feed Management on dairy operations. The tool was designed to be implemented by a consulting nutritionist in cooperation with the dairy producer. After further study of how we might implement this tool in the region, it became apparent to us that the Feed Management 592 Practice Standard had not been adopted in our region, or broadly across the U.S. In early 2005, we decided to submit a Conservation Innovation Grant to NRCS to develop and implement a National Feed Management Program. Faculty from eight Land Grant Universities collaborated and submitted a proposal to “Development and Integration of a National Feed Management Education Program and Assessment Tool into a CNMP.” In September 2005, we learned that we would be awarded $425,000 to develop and implement a National Feed Management Program. That project is currently under development and is projected to be completed by the fall of 2007.
