Especificações de ingredientes para rações, explicadas parâmetro a parâmetro
Cada parâmetro de um certificado de análise existe por um motivo. Esta biblioteca explica o que cada especificação mede, como é analisada, quais valores são típicos e o que o comprador deve verificar antes de aceitar uma carga — sem recomendar ou classificar fornecedores.

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.
Ler a referênciaMoisture
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.
Ler a referênciaAsh
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.
Ler a referênciaFat, 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.
Ler a referênciaCrude 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.
Ler a referênciaNutritional 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.
Ler a referênciaAmino 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.
Ler a referênciaDigestibility
Digestibility expresses the proportion of a nutrient the animal can actually absorb; it converts an analytical composition into a nutritional value.
Ler a referênciaPhysical 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.
Ler a referênciaPurity, 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.
Ler a referênciaContaminants & 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.
Ler a referênciaHeavy 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.
Ler a referênciaOxidation & 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.
Ler a referênciaMicrobiological Quality
Microbiological specifications control Salmonella, Enterobacteriaceae, moulds and yeasts, protecting animal health, plant hygiene and — for several species — the human food chain.
Ler a referênciaContract & 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.
Ler a referênciaShelf 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.
