On-Farm Feed Storage Science: Preventing Mycotoxins, Aflatoxins, and Rancid Fat Degradation
The Lethal Impact of Aflatoxin B1 in Fish
Aflatoxin contamination at levels as low as 20 parts per billion (ppb) induces severe liver degeneration, suppressed immune response, and internal hemorrhaging in catfish. Often, farmers blame diseases when the true killer was moldy feed stored incorrectly.
Strict Warehouse Storage Standards
- Always Use Wooden or Plastic Pallets: Never place feed bags directly on bare concrete. Maintain at least 15 cm of ground clearance.
- Wall Offset (30 cm Minimum): Keep stacks 30 cm away from perimeter walls to facilitate cross-ventilation and prevent condensation absorption.
- First-In, First-Out (FIFO): Strictly rotate stock. Extruded feeds containing omega fats degrade through lipid peroxidation after 90 days in hot tropical warehouses.
