- Deoxynivalenol and Zearalenone natural occurrence in swine feedstruffs and histopathological analysisPublication . Meier, Katia Wanusa de Almeida; Duarte, Sofia Alexandra Giestas CancelaDeoxynivalenol (DON) and Zearalenone (ZEA) are the most frequent and toxicologically important Fusarium mycotoxins detected in cereal grains and feedstuffs, causing toxic effects that impair the performance of farm animals, with pigs being the most susceptible species. The objectives of this study were to evaluate the occurrence of DON and ZEA in feed cereal grains and compound feed destined to swine consumption, to perform a histopathological study using liver samples collected from gilts and sows fed with these compound feeds. Twelve ingredients (unprocessed maize, barley, wheat, bran, rapeseed, soybean) and twenty-six samples of swine compound feed were analyzed. The histopathological study was performed using samples from slaughtered pigs that had been fed the analyzed compound feed for at least two weeks. Results showed that 71.1% of the samples were positive for ZEA and 78.9% for DON. Histologically, diffuse degenerative changes compatible with hepatosis were observed.
