Abstract
Five male and 5 female Duroc pigs 12-14 weeks of age were fed a practical ration containing 450 parts per billion aflatoxin B1. At 8 months of age a reproduction experiment was conducted while the animals continued on the same aflatoxin ration. Weight gains and spermatogenesis were normal in the 5 young males autopsied after 248 days. A questionable lesion of the hepatocytes in 3 boars was the only microscopic abnormality detected. The 5 females were autopsied after 325 days which included normal periods of growth, pregnancy, and lactation. Microscopic lesions were present in the livers of each sow but were minimal in severity. Pigs weaned at 6 weeks of age from the females were normal in size and number per litter and no microscopic lesions were detected.
