兔饲料原料品质控制：霉菌毒素检测与原料筛选标准

Feed ingredient quality is the first barrier protecting rabbit herd health. Rabbits are extremely sensitive to feed toxins; moldy feed is the primary cause of widespread diarrhea and reproductive failure. Establishing strict ingredient quality control is crucial.

Six key mycotoxin limit standards: aflatoxin B1 no more than 20 mcg/kg (no more than 10 mcg/kg for kits and breeding rabbits), zearalenone no more than 100 mcg/kg, deoxynivalenol no more than 1000 mcg/kg, fumonisins no more than 5000 mcg/kg, ochratoxin A no more than 50 mcg/kg, T-2 toxin no more than 100 mcg/kg.

Sensory evaluation is the first quality control step. Corn kernels should be plump, golden yellow, free of mold spots and insect damage. Soybean meal should be light yellow to yellow-brown, with roasted bean aroma and no mold or caking. Wheat bran should be fresh without rancid smell or clumping. Alfalfa meal should be emerald green with grassy aroma and distinct fibers. Any discolored, off-smelling, or caked ingredients must not enter storage.

Incoming inspection process: after each batch arrives, first test moisture content (corn no more than 14%, soybean meal no more than 13%), then perform rapid aflatoxin B1 testing (test strip or ELISA). After passing, sample for comprehensive mycotoxin screening.

Storage management essentials: keep ingredient warehouses dry and ventilated with relative humidity below 65% and temperature no higher than 25 degrees Celsius. Store old and new ingredients separately; use first-in-first-out. High-moisture ingredients such as corn should be used within one week. Thoroughly clean and disinfect warehouses quarterly to prevent pest and rodent infestation.
