Aflatoxin deposition and clearance in the eggs of laying hens

摘要: Hens fed a diet containing 3310 μg of AFB1 and 1680 AFB2 per kg feed for 28 days showed significant decrease in egg production weights by wk 3 4 feeding, respectively. Transfer aflatoxins to the eggs occurred rapidly, reaching maximum levels after 4–5 days, remained relatively constant throughout aflatoxin feeding. The mean values combined residue were less than 0.5 μg/kg. Levels AFB2, AFM1 AFM2 similar yolk albumen while B1 B2a higher yolk. Upon removal aflatoxin-containing diet, residues decreased rapidly. Clearance from faster Thus, no detected 5 7 withdrawal, No could be recovered whole feeding aflatoxin-free days.
