PROTEINS

Proteins from both plant and animal sources are used in compound feed formulation.This practice ensures that a balance amino acid profile is achieved to meet specific animal requirements.In addition diversity of protein sources are important for economic and availability point of view. Exception to this general practice is the use of all vegetable source proteins in compound feed, which are aimed to meet the specific requirements of some consumer groups.

Proteins are made up of a specific amino acid combination, which is specific for each protein.
Digestion of proteins in the intestines requires specific enzymes and the process breaks down the amino acids into molecular level for absorption into blood circulation. The absorption of digested protein component from the digestive tract is by active process. 

In the body, protein components are assimilated to form parts of structural components in tissues such as muscles, connective tissues, skin, hair, feather etc. 

Protein can be used, as a source of energy in compound feed but it is relatively expensive. 

Proteins are part of many enzymes and also a part of blood clotting factors.
