Abstract
Naturally OA[ochratoxin A]-contaminated feed was fed to 4 sows throughout 2 consecutive periods of gestation and lactation. Two sows were given 700 and 2 1400 .mu.g OA/kg feed, while 2 sows were on toxin-free diet. The creep feed contained 500 or 1000 .mu.g OA/kg. All sows and piglets appeared clinically normal. OA residues were not detected in the newborn pigs or the sow milk. The piglets showed normal performance up to weaning at 8 wk. OA was found in serum, kidney, liver and muscle. After 141 days on toxin free diet no residues of OA were found in serum or kidneys. The kidneys were macroscopically normal.
