Energy is species-specific
An ingredient has no single energy value. Poultry metabolisable energy, swine net energy and ruminant digestible energy are different systems with different assumptions. Quoting one number across species is a formulation error, not a specification shortcut.
Matrix values are estimates with variance
Published energy tables represent population averages. Real cargo varies with origin, harvest year, processing intensity and residual oil. Buyers who formulate close to the constraint should either build in a safety margin or verify energy-relevant parameters shipment by shipment.

- —Which energy system and species the quoted value refers to
- —Residual oil, starch and fibre values that drive the calculation
- —Whether the value came from a published table, a supplier claim or a measured assay
Risques typiques
- —Diet energy drifting below target across a production cycle
- —Cost per unit of energy being misjudged between origins

Questions fréquentes
Can energy be tested on arrival?
Not directly in routine trade. Energy is predicted from measured composition — oil, starch, fibre, protein and ash — using species-specific equations, or determined in animal trials, which is outside normal cargo verification.

Fat content sets the energy density of an ingredient and, together with fatty-acid profile and oxidation status, determines both nutritional value and storage stability.
Digestibility expresses the proportion of a nutrient the animal can actually absorb; it converts an analytical composition into a nutritional value.
Crude fibre is a legacy proximate measure of indigestible plant structure; NDF, ADF and total dietary fibre describe the same material more precisely and are what modern formulation uses.
