Time and temperature consume specification
Vitamin potency, oxidation indices and microbiological load all move during storage. A certificate from production tells you where the material started; the storage record tells you how far it has travelled since.
Cross-contamination in shared storage
Shared silos, flat stores and warehouses transfer medicated feed residues, allergens, prohibited animal proteins and pest activity. Ask what occupied the space before, and what sits beside it now.
確認すべき事項
- —Production date and elapsed storage time
- —Storage temperature and humidity conditions
- —Previous contents of the storage structure and cleaning records
- —Pest control and fumigation records, including chemicals used
主なリスク
- —Undeclared ageing of long-held stock
- —Fumigant residues
- —Pest infestation arriving with the cargo
よくある誤り
- —Not asking for production date at all
- —Assuming warehouse storage is climate controlled
よくある質問
How do I detect long-stored material?
Compare production date against delivery date, then look for the fingerprints of ageing — rising free fatty acids and anisidine value, falling vitamin assay, caking, and insect fragments on microscopy.

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.
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.
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.
Microbiological specifications control Salmonella, Enterobacteriaceae, moulds and yeasts, protecting animal health, plant hygiene and — for several species — the human food chain.
