Basics of animal nutrition Feeding the rumen microbes 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

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
o True Protein (amino acids)
o Endogenous protein
o Rumen microbial protein
o Dietary protein
