WebDec 13, 2024 · It's a notion rooted in the concepts of classical physics as elucidated by Sir Isaac Newton. The formula for the energy of motion is: KE=0.5\times m\times v^2 K E = 0.5×m ×v2. where KE is kinetic energy in joules, m is mass in kilograms and v is velocity in meters per second. 00:03 12:50. WebCaloric values (protein 5.6 Mcal kg-1, carbohydrate 4.2 Mcal kg-1, and fat 9.4 Mcal kg-1) are applied to the digested nutrients to obtain digestible energy values. Equations to calculate ME and net energy from digestible energy vary, depending upon whether the feed ingredient is a forage, concentrate, animal protein, or fat supplement.
