AA Balancing

The information below provides a fundamental basis for undertanding the NRC 2001 AA sub-model, the post NRC work done to establish MP-Lys and MP-Met formulation targets for stipulated milk and milk protein yields, and the implementation of the post NRC work provided in the AA and MP Calculator.
