3) Gross energy
Gross energy (or heat of combustion) is measured as the energy released as heat when a compound undergoes complete combustion with oxygen in a bomb calorimeter. It can be predicted relatively accurately from the chemical composition.
Metabolizable energy
Metabolizable Energy (ME) is the net energy remaining after fecal and urinary energy loss, and represents the energy available for growth or reproduction and for supporting metabolic processes such as work (locomotion) and respiration (thermoregulation, maintenance metabolism, HIF).
Metabolizable energy (ME): the amount of energy in the feed minus the energy lost in the feces and urine.
Net energy
(NE): the amount of energy in the feed minus the energy lost in the feces, urine, and in heat production through digestive and metabolic processes, i.e. heat increment.
