The prime fatty acids contained in chicken fat include oleic (40.9 wt%), palmitic (20.9 wt%), and linoleic (20.5 wt%) acids (Wyatt et al., 2005). 0000005843 00000 n Thus, the heat capacity is (6-4) A similar relation is used to determine the heat of combustion. It is measured in units of energy per unit of the substance, usually mass, such as: kcal/kg, kJ/kg, J/mol, Btu/m³. Most of the energy our bodies need comes from carbohydrates and fats.

True metabolizable energy of feather meal. MAF (Moisture and Ash Free) or DAF (Dry and Ash Free) indicates that the fuel heating value has been measured in the absence of inherent moisture and ash forming minerals.
