  • Oversee the work of and give guidance to the Modeling and Feed Composition Committees.
  • Collaborate with the National Academies' Board on Agriculture and Natural Resources - National Research Council.
  • Identify the current state of coordination and networking within the science(s) of animal nutrition and among its experts using broad methodologic foundations which are quickly becoming a prerequisite for researchers and practitioners working in animal science and related fields.
  • Explore temporal, geospatial, topical, and network analysis and visualization of animal nutrition at the micro (individual), meso (local), and macro (global) levels.
  • Define high priority animal nutrition issues.
  • Address gaps among existing collaborations to facilitate solutions to high priority issues.


  • The Modeling and Feed Composition Committees have been established and work is ongoing.
