Metabolic Energy
Metabolic energy (short ME ; metabolizable energy, also convertible energy ) is the total amount of usable energy that is available to livestock from a feed.
Metabolic energy is important for evaluating ruminant feed. The total energy content (GE) of feed minus the energy that is excreted with the faeces (KE) results in the amount of energy that is used to evaluate horse feed. In order to get to the value of the metabolic energy, one must subtract the amount of energy that is excreted with urine and digestive gases. With horses these losses can be neglected.
The net energy lactation (NEL) is less than the metabolic energy. This only describes the amount of energy that is available for milk production ( lactation ) after the energy-intensive digestion process .
The term is also used generally in connection with metabolic processes in the life sciences .
