This study aimed to assess the effects of a diet containing 20.8 mg FB1 + FB2/kg over four and nine days on oxylipin (OL) profiles in liver brain chickens. A total 96 OLs, derived from seven polyunsaturated fatty acids (PUFAs) via cyclooxygenase (COX), lipoxygenase (LOX), cytochrome P450 (P450), non-enzymatic pathways, were measured using HPLC-MS/MS. In liver, significant increase epoxide P450-derived OLs was detected by day 4, with smaller but notable increases COX- LOX-derived 9. These alterations independent whether parent PUFA ω6 or ω3. However, 18-carbon (C18) PUFAs, such as linoleic acid alpha-linolenic acid, showed greater compared those C20 C22 PUFAs. The diol/epoxide ratios decreased at days, suggesting that fumonisins did not induce an inflammatory response. brain, most discriminative ω3-PUFAs, including docosahexaenoic docosapentaenoic LOX pathway. By several arachidonic spanning all enzymatic became discriminative. general, 4 then returned initial levels. Taken together, these results show strong are both specific distinct.

Identifying biomarkers of mycotoxin effects in chickens will provide an opportunity for early intervention to reduce the impact mycotoxicosis. This study aimed identify whether serum enzyme concentrations, gut integrity, and liver miRNAs can be potential fumonisin B1 (FB1), deoxynivalenol (DON), zearalenone (ZEA) toxicity broiler birds as 14 days after exposure. A total 720 male chicks were distributed six treatment groups: T1: control group (basal diet), T2 (2 FB1 + 2.5 DON 0.9 ZEA), T3 (5 0.4 0.1 T4 (9 3.5 0.7 T5 (17 1.0 0.2 T6 (21 3.0 all mg/kg diet. On d14, there no significant differences body weight gain (BWG) groups when compared (p > 0.05), whereas on d21, showed significantly reduced BWG < 0.05). upregulation miRNAs, gga-let-7a-5p (14.17-fold), gga-miR-9-5p (7.05-fold), gga-miR-217-5p (16.87-fold), gga-miR-133a-3p (7.41-fold), gga-miR-215-5p (6.93-fold) 0.05) elevated fluorescein isothiocyanate-dextran (FITC-d) aspartate aminotransferase (AST), creatine kinase (CK) levels exhibited phosphorus, glucose, potassium, while protein, FITC-d, AST, CK increased These findings suggest that CK, could serve detecting exposure chickens.
