Protein Bioavailability in Animal Model.

All the nutrients in food are not absorbed by our system. The relative amount of nutrition from an administered dosage through which it enters the system of circulation and the rate at which the level of nutrition appears in the systemic circulation is called 'bioavailability'. Although plant foods have high nutrient contents our digestion system cannot absorb it fully. Hence, it becomes necessary to determine the bioavailability of the administered sample to check the overall effect on the living system. Animal food preparation, protein bioavailability in animal model, food efficiency, apparent digestibility, protein digestibility tests, etc., are mentioned in well explained methodologies.
