                                The energy an animal derives from its food is a critical metric in nutrition, and approximately 19% of a ruminant's digestible energy may be lost before it can be fully metabolized. Digestible energy (DE) quantifies the portion of an animal's dietary energy that is actually absorbed, excluding the energy lost through feces.
