Energy factors
(1) In this clause -
energy factor means the metabolisable energy (ME) of the food component calculated according to the following formula, expressed in kilojoules per gram of food component, rounded to the nearest whole number -
ME = GE − FE − UE − GaE − SE
Where -
ME means metabolisable energy
GE means gross energy (as measured by bomb calorimetry)
FE means energy lost in faeces
UE means energy lost in urine
GaE means the energy lost in gases produced by fermentation in the large intestine
SE means the energy content of waste products lost from surface areas
(2) Energy factors in relation to the food components listed in column 1 of Table 1 and column 1 of Table 2 to this subclause are specified in the corresponding entry in column 2 of Table 1 and Table 2.
