Basics of animal nutritionProtein

Energy

Micro nutrients

Feeding the rumen microbes


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

3:1Detoxification of amino acids is an energy consuming

process!!

Amino acids are bricks of all protein

Diet formulation shift

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

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


How do we apply Amino Acid Balancing?
