Taken from IPCC Report 2006 Vol 4, Chapter 10: Emissions from Livestock and Manure Management: V4_10_Ch10_Livestock.pdf Emission factor development An emission factor for each animal category was developed following Equation 10.21: EQUATION 10.21 CH4 EMISSION FACTORS FOR ENTERIC FERMENTATION FROM A LIVESTOCK CATEGORY EF = (GE * (Ym / 100) / 55.56 Where: EF = emission factor, kg CH4 head-1 yr-1 GE = gross energy intake, MJ head-1 day-1 Ym = methane conversion factor, per cent of gross energy in feed converted to methane The factor 55.65 (MJ/kg CH4) is the energy content of methane This emission factor equation assumes that the emission factors are being developed for an animal category for an entire year (365 days). While a full year emission factor is typically used, in some circumstances the animal category may be defined for a shorter period (e.g., for the wet season of the year or for a 150-day feedlot feeding period). In this case, the emission factor would be estimated for the specific period (e.g., the wet season) and the 365 days would be replaced by the number of days in the period. The definition of the period to which the emission factor applies is described in Section 10.2.
