Formula for GE calculations, GE(Old GE formula) = 4,143 + 56 × EE + 15 × CP – 44 × Ash. . GE 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).
How do you calculate metabolic energy of a feed?
At times, meals of exceptionally poor quality will have appreciable amounts of foreign material. The ME of SBM can be estimated from this equation: ME (kcal/kg) = 2778 - 66 (% crude fiber), assuming a dry matter content of 88%.
How do you calculate the energy of a chicken feed?
It is calculated based on the EU Regulation (EC 152/2009 annex VII) from the chemical composition of the feed mixture: ME (MJ/kg) = (15.51 CP + 34.31 CFat + 13.01 sugar + 16.69 starch )/1000, where feed composition is expressed as g/kg.
How is energy measured in animal feed?
Gross energy (GE) is the total amount of chemical energy in the diet consumed. It is also known as the heat of combustion. GE content of feed is measured as heat liberated during complete burning (oxidation) of the feed sample and is determined by an apparatus called a bomb calorimeter.
How do you calculate energy in food plan?
The formula is Energy (in Kcal) = 4x (Proteins and carbohydrates mass in grams) + 9 x mass of fat in grams.
