Diet
Daily allocation of food or feed
Ration
All plant’s structural carbohydrates such as cellulose
Crude fiber
Difference between original sample weight and sum of water, ether extract, crude protein, crude fiber, and ash= digestible carb portion of diet. ( % NFE = 100 - % moisturizer - % crude protein - %)
Nitrogen-free Extract (NFE)
The capability of doing work
Energy
Heat required to raise the temperature of one gram of water to 1 degree Celsius
Calorie
Complete potential energy in the feed. Quantity of heat resulting from complete oxidation (combustion) of food, feed, or other substance (fuel/food energy)
Gross Energy (GE)
Intake of GE minus lost energy in feces (FE)
Digestible Energy (DE)
Intake of GE minus fecal energy (FE) minus urine energy (UE) minus gases
Metabolizable Energy (ME)
Portion of energy that is available to the animal for the maintenance of various productive purposes. NE = ME - Heat increment (HI) and heat of fermentation (HF)
Net Energy (NE)
H2O is the substrate (water required for metabolism of organic compounds)
Hydrolysis
H2O is the product
Oxidation
