Feed Conversion Efficiency

To estimate an organisms total growth efficiency you need to know the complete feed ingestion from birth till death, the complete cellular metabolism and the total amount of feces released.

The energy used to stay alive without any growth is called energy used for maintenance.

An approximation can be made using respiration and calculations of metabolism

The growth efficiency is equal to, open brackets, the food intake, minus, the feces, minus, the metabolism, close bracket, divided by, the food intake.

Where GE G E is Growth Efficiency

FI F I is Food Intake

FO F O is Feces

ME M E is Metabolism

Units used for calculating the growth efficiency of an organism are joules, which is the SIinternational system-unit of energy.

Metabolism can be estimated via the respiration of an organism
