Metabolizable Protein
Formulating for Better AA Efficiency
How to optimize milk protein yield, improve cost efficiency, and reduce nitrogen excretion? The answer: Balance dairy rations for essential amino acids (EAA) rather than their aggregate, metabolizable protein (MP). Canada’s Dr. Hélène Lapierre and U.S. researchers updated the NASEM 2021 guide to MP and EAA, which now recognizes requirements and “efficiency of utilization” of individual EAA.
