Think all Requirement and Supply Models Function the Same?

Significant differences exist between CPM, CNCPS 6.1 and NRC 2001 predictive mechanisms.

Do you know what they are and how they affect the diets you formulate?

The Power Point Presentation "Balancing for AA With NRC 2001" examines differences in the predictive mechanisms of CPM, CNCPS 6.1 and NRC 2001. If you use any of these models to formulate diets or plan on using them, you will want to see this.

Please Note the Following

Data from the CPM session files that appears in the power point presentation were generated with NO changes to efficiency constants or rates. These are "out-of-the-box" CPM evaluations - they are what you get if you are NOT making adjustments to CPM constants and rates.

The CNCPS 6.1 data are also from "out-of-the-box" evaluations which is the only option with CNCPS 6.1. While rates may be adjusted, efficiency constants are NOT accessible by the user NO ADJUSTMENTS CAN BE MADE.

  • To use the NRC evaluation software copy of the diet download the file and expand the Zip archive at the location where you wish to place it. Then navigate to it with the NRC Evaluation software and open simulation file.
  • To use the Formulate2 Export Data Set Zip Archive copy it to a flash drive and expand the archive to the root folder of the drive. Then use Formulate2's Restore from Back Up function to view the diet. When you are finished viewing the Export Data Set, use the Restore from Cache menu option to restore your original data.
