Spécifications des matières premières pour aliments, expliquées paramètre par paramètre
Chaque paramètre d'un certificat d'analyse existe pour une raison. Cette bibliothèque explique ce que mesure chaque spécification, comment elle est analysée, quelles valeurs sont typiques et ce que l'acheteur doit vérifier avant d'accepter une cargaison — sans recommander ni classer de fournisseur.

Nutrient composition
Crude Protein
Crude protein is nitrogen content multiplied by a conversion factor (usually 6.25); it estimates total protein but says nothing about amino-acid quality or digestibility.
Lire la référenceMoisture
Moisture is water content expressed as a percentage; it dilutes every other nutrient, drives mould and mycotoxin risk in storage, and is the single most disputed parameter in bulk feed trade.
Lire la référenceAsh
Ash is the inorganic residue after complete combustion; it indicates total mineral content and, in protein meals, is a practical marker for bone, shell, sand or mineral adulteration.
Lire la référenceFat, Oil & Residual Oil
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.
Lire la référenceCrude Fibre & Fibre Fractions
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.
Lire la référenceNutritional performance
Energy Values (ME, NE, DE)
Energy values are calculated or measured estimates of the usable energy an ingredient delivers to a specific species; they are matrix values, not analytical certificates.
Lire la référenceAmino Acid Profile
The amino-acid profile — and above all digestible lysine, methionine, threonine and tryptophan — is what protein ingredients are actually bought for in modern formulation.
Lire la référenceDigestibility
Digestibility expresses the proportion of a nutrient the animal can actually absorb; it converts an analytical composition into a nutritional value.
Lire la référencePhysical properties
Particle Size & Granulometry
Particle size distribution governs mixing homogeneity, pellet quality, digestive efficiency and segregation risk, and is specified as a geometric mean diameter with a distribution, not a single sieve figure.
Lire la référencePurity, Foreign Matter & Adulteration
Purity covers everything that should not be in the cargo — foreign matter, other-grain admixture, hulls, soil, packaging debris and deliberate adulterants — and is verified by physical inspection plus targeted analysis.
Lire la référenceContaminants & safety
Mycotoxins
Mycotoxins are toxic fungal metabolites — aflatoxins, DON, zearalenone, fumonisins, ochratoxin A, T-2/HT-2 — that form in the field and in storage and are regulated with species-specific limits.
Lire la référenceHeavy Metals & Trace Contaminants
Heavy metals — lead, cadmium, arsenic, mercury — accumulate in animal tissues and are regulated in feed materials, with mineral sources and marine ingredients carrying the highest inherent risk.
Lire la référenceOxidation & Rancidity Indices
Oxidation degrades fats and fat-soluble vitamins, and is tracked through peroxide value, anisidine value, TOTOX and free fatty acids — a set that must be read together, not individually.
Lire la référenceMicrobiological Quality
Microbiological specifications control Salmonella, Enterobacteriaceae, moulds and yeasts, protecting animal health, plant hygiene and — for several species — the human food chain.
Lire la référenceContract & measurement
Tolerances & Analytical Variation
Every analytical result carries measurement uncertainty; contractual tolerances define how much variation is accepted before a price adjustment, rejection or claim is triggered.
Lire la référenceShelf Life & Stability
Shelf life is the period over which an ingredient retains its declared specification under defined storage conditions; it is a conditional statement, not a fixed property of the material.

Aliments finis pour mes animaux
Aliments volailles, bovins lait et viande, porcs et aquaculture, et contrats d'aliments en vrac.
Ingrédients, prémélanges et additifs
Tourteau de soja, céréales, DDGS, farine de poisson, acides aminés, vitamines, minéraux, prémélanges et additifs.
Les fournisseurs ne sont contactés qu'après une revue humaine autorisée. Projets d'usine et d'équipement généralement à partir de 250 000 USD ; l'approvisionnement en aliments et ingrédients n'a pas ce minimum.
