How do we make milk?
Amino Acids
from Protein
Milk Protein
≠We need amino acids
to bypass the microbes in the rumen
Protein drives milk volume and content

Optimal milk production
We need:• Certain limiting amino acids (Lys, Met)• In a certain ratio (Lys 3 : 1 Met)• And normal feedstuffs don’t supply this:
• Not enough• Not the right ratio
• So we need to supplement them• We need RUP

Protein and Amino acids
• Protein supplies Nitrogen • And protein are made up of amino acids (AA)• There are over 700 AA that exist in nature• 20 serve as building blocks for protein• Of these, 10 are classified as nutritionally
essential

Diet formulation shift
• Before: diets formulated on Crude Protein (CP)• Current: metabolizable protein requirements
