The ME of SBM can be estimated from this equation: ME (kcal/kg) = 2778 - 66 (% crude fiber), assuming a dry matter content of 88%. In solvent-extracted meals, the level of lipid is generally low and its variation does not greatly affect metabolizable energy.
How do you calculate metabolizable energy?
Universal values for metabolizable energies1For proteins: MEp = HCp (Ap) − Up = 5.65 (0.92) − 1.25 = 4.0 kcal per gram of protein.2For fats: MEf = HCf (Af) = 9.4 (0.95) = 8.9 kcal per gram of fat.3For carbohydrates: MEc = HCc (Ac) = 4.1 (0.97) = 4.0 kcal per gram of carbohydrate.Calculating the metabolizable energy of macronutrients: a critical review ...

How do you calculate digestible energy?
For example, Digestible Energy (DE), the value utilized in equine nutrition, is calculated by subtracting the gross energy in the feces from the gross energy consumed by the animal. In other words, the Digestible Energy is the amount of energy an animal consumes minus what is lost in the manure.
