Stomach | provides food storage, produces hydrochloric acid, and has a lining of mucus to protect it from it's acidic environment. Moves food to small intestines |
Small Intestines | Mixes food with bile, digests sugars and strings of amino acids. Absorbs nutrients. |
Large Intestines | Absorbs water and electrolytes, moves waste to rectum and anus. |

Bioavailability | amount of nutrient absorbed from the GI tract in a form the body can use. |
As- fed basis | concentration of nutrients in food in the form consumed by the animal; includes moisture content of the food. |
Dry matter basis | method of expressing a food's nutrient content on a moisture- free basis |
Energy Basis | concentration of a nutrient in food expressed per unit of energy, usually per 100 kilocalories |
