Short-term ingestion of deoxynivalenol in naturally contaminated feed alters piglet performance and gut hormone secretion

The mycotoxin deoxynivalenol (DON) generally exists in cereals and affects human and animal health. The aim of this study is to analyze the impacts of DON in naturally contaminated feed on piglet growth performance and intestinal hormone secretion in the short term. We randomly divided 5-week-old piglets into four groups: Control, DON 1,000, DON 2,000 and DON 3,000 groups. Piglets received a feed naturally contaminated with DON (approximately 400, 1,000, 2,000 or 3,000 μg/kg) for 21 days. Body weight showed no significant difference following exposure to DON. The balance of anti-oxidation and oxidation was disrupted by DON after 21 days. The concentration of tumor necrosis factor-alpha (TNF-α) and cyclooxgenase-2 (COX-2) significantly increased (p
