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. 23 янв. 2017 г.


How do you calculate metabolizing 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.

What is the digestible energy?

Digestible energy (DE): the amount of energy in the feed minus the amount of energy lost in the feces. Metabolizable energy (ME): the amount of energy in the feed minus the energy lost in the feces and urine.

How do you calculate the energy of a feed?

ME (Kcal/kg) = 3.82 x g.1GE(Old GE formula) = 4,143 + 56 × EE + 15 × CP – 44 × Ash. ... 2GE for animal feed, GE = 5.7× g protein +9.4× g fat +4.1× (g NFE + g fiber), The calculation for nitrogen free extract is: % NFE = 100 % – (% EE + % CP + % Ash + % CF).

What is digestible energy in animal nutrition?

Digestible Energy (DE): Digestible energy provides an indication of the actual amount of energy from a feed that can be available for use by the animal. It is estimated by subtracting energy lost in the feces (fecal energy or FE) from the gross intake energy (GE), (i.e., DE = GE ? FE).
