Especificaciones de ingredientes para piensos, explicadas parámetro a parámetro
Cada parámetro de un certificado de análisis existe por una razón. Esta biblioteca explica qué mide cada especificación, cómo se analiza, qué valores son habituales y qué debe verificar el comprador antes de aceptar una carga, sin recomendar ni clasificar proveedores.

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.
Leer la referenciaMoisture
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.
Leer la referenciaAsh
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.
Leer la referenciaFat, 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.
Leer la referenciaCrude 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.
Leer la referenciaNutritional 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.
Leer la referenciaAmino 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.
Leer la referenciaDigestibility
Digestibility expresses the proportion of a nutrient the animal can actually absorb; it converts an analytical composition into a nutritional value.
Leer la referenciaPhysical 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.
Leer la referenciaPurity, 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.
Leer la referenciaContaminants & 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.
Leer la referenciaHeavy 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.
Leer la referenciaOxidation & 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.
Leer la referenciaMicrobiological Quality
Microbiological specifications control Salmonella, Enterobacteriaceae, moulds and yeasts, protecting animal health, plant hygiene and — for several species — the human food chain.
Leer la referenciaContract & 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.
Leer la referenciaShelf 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.
