Feeding Management in Nutrition and Nutrient Management for Livestock – Poultry Professionals
This was a successful year for the WIN2ME (Western Integrated Nutrition and Nutrient Management Education) project. The educational materials and events conducted in 2004 were well received by the audiences that attended. A summary of educational materials and education venues during 2004 include: 1 survey, 5 workshops, 1 field day, 15 fact sheets, 16 PowerPoint presentations, and 2 newsletter articles. Four workshops were targeted toward individuals with limited to no experience in animal nutrition, and one workshop was targeted toward animal nutritionists. A notebook that included fact sheets and PowerPoint presentations was provided for participants at the workshops.
- 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
Provide training in the use of computer models and software for strategic ration balancing, whole farm nutrient balance, and whole farm economics
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
Provide workshop materials that could be used by other states in the region.
There were many activities accomplished associated with the WIN2ME project since the project’s initiation in September 2003. There have been 10 scheduled conference calls with the WIN2ME team to develop materials, schedule events, and plan activities associated with the grant. There were also multiple conference calls separate from the WIN2ME core project to plan specific events. For example, there were 4 conference calls directly related to planning the Bueler Field Day, and multiple conference calls to plan the Phosphorus Workshop. The WIN2ME project was advertised in the Progressive Dairyman, Capital Press, Commercial Review, and Idaho Dairy Monthly during 2004. Specific events associated with the WIN2ME grant were advertised through the WSU Dairy Newsletter on the WSU Dairy website.
Five workshops were conducted during 2004

One field day was conducted in 2004.
Bueler Field Day, June 29, 2004, Snohomish, WA. The purpose of this field day was to educate dairy producers and others associated with animal agriculture about nutrient management data collection and data analysis and interpretation, and to discuss grass silage management strategies that impact dairy cattle nutrition. 77 attended
Fact Sheets and PowerPoint Presentations were developed:
Each fact sheet from the Phosphorus Workshop was peer reviewed by 2 people. These articles will be made available on a Nutrient Management website once it is available.
Other fact sheets from the workshops will also be made available on the website in 2005.
The nutrient management website is still in development. It is in the final phases of review, and is very close to functioning. However, the programmer that was working on the development of the website has not been able to complete the task, and another website developer is being recruited.

Work Left to Do
Develop assessment tools (check list) that can be utilized by agricultural professionals to help livestock and poultry producers assess what feed management practices they currently use, could potentially use, or would not use on their specific operation that would help to reduce nutrient loading. The goal of the assessment tools would be to be used at both a local level and a national level.
Plan workshops and field days for 2005.
Possible workshops include:
Minerals and the Environment
Nutrient management education for beef industry
Advanced feed management education for nutritionists
Nutrition and nutrient management training for nutritionists at the Pacific Northwest Animal Nutrition Conference
Feed management education relevant to nutrient management issues for horse producers
Possible field days
Oregon field day with dairy producers
Nutrient management field day on dairy in Idaho
Impacts and Contributions/Outcomes
-Create regional-specific materials on Feeding Management education that complement the National Livestock Environmental Stewardship Curriculum
Fifteen fact sheets were developed and provided to workshop participants. This educational material is available for workshop participants to use as reference material when working with producers
-Develop a network of professionals in the region that can assist each other with feed management and nutrient management issues
Many people have contributed to the success of the WIN2ME project this year. The network of people has been categorized into 4 groups (resource people, collaborators, workshop participants, and field day participants). Contact information for all of these individuals is currently in a spreadsheet, and is used by the WIN2ME team as needed.
Four groups of people have been identified
Resource people (grant personnel) – Joe Harrison, Ron Kincaid, Lynn VanWieringen, Mike Gamroth, Troy Downing, Patrick French, Alex Hristov, Ron Sheffield
Collaborators – Alan Rotz – presentation of IFSM (Integrated Farm System Model), William Chalupa (CPM – Dairy Cattle Ration Formulation Model)
Phosphorus Workshop – 37+ attended
WADE Workshop – 9 attended
Pacific Northwest Animal Nutrition Post Conference Workshop – 28 attended
Ag and Water Quality in the Pacific Northwest Workshop – 8 attended
Oregon Conservation District Employee Workshop – ~45 attended
Field day participants
Bueler Field Day – 77 attended
-Increase the understanding of the positive environmental and economic role that feed management can play in livestock operations in the region
The workshops were planned to contain material that would address positive environmental and economic role that feed management can play. The evaluations are evidence of the knowledge that was gained from participants in these areas. In each evaluation, there were questions that asked for a ‘before workshop knowledge rating’ and ‘after workshop knowledge rating.’ For all the questions asked in this part of the evaluation there was an overall increase in knowledge gained about feed management effects on the environment and economic impacts. Please refer to the attached evaluation summaries.
-Increase the knowledge of whole farm nutrient management by professionals

Please refer to the attached evaluation summaries.
-Create an awareness and competency with computer tools that are available to assist with evaluation of feeding management and whole-farm nutrient management
Three computer models were demonstrated at various workshops
Whole-farm Balance Spreadsheet tool – This tool was developed by Joe Harrison toevaluate how different management changes affect whole-farm balance of nitrogen and phosphorus. The spreadsheet was designed to fit on one computer screen so the user can instantly see how changes in a management practice can impact whole-farm balance.
IFSM – Integrated Farm System model was developed by Alan Rotz, and is designed to evaluate whole-farm nutrient balance. This model was presented at the post conference workshop of the Pacific Northwest Animal Nutrition Conference to introduce animal nutritionist to whole-farm nutrient balance.
CPM – Cornell-Penn-Minor Ration Evaluator was presented by Bill Chalupa at the post conference workshop of the Pacific Northwest Animal Nutrition Conference to demonstrate how to reduce nitrogen content of a dairy cattle diet while still meeting the nutrient requirements of the cattle and maintaining milk production.
-Increase the adoption of Feed Management and other related practices on livestock facilities beyond the dairy sector
The evaluations that were completed at each educational event have a question that states ‘Please list one or more things that you intend to do in your work as a result of attending this session.’ The results listed below are responses that were received at the various educational events, and demonstrate that there was an interest in using the educational information presented.
