Abstract

Purpose of this study was to investigate the age-dependent, short-term effects of T-2 toxin (5.77 mg T-2 and 1.40 mg HT-2 toxin/kg feed) or deoxynivalenol (DON) (4.86 mg DON and 1.39 mg 15-acetyl-DON/kg feed) in one and three weeks old broiler chicken to observe the changes in parameters of lipid peroxidation, glutathione redox system, and expression of genes related to glutathione redox system in the first 24 h of mycotoxin exposure. Glutathione-redox system responsed to T-2 toxin exposure in both age groups for T-2 toxin in the first 8 h of exposure, while a reactivation was observed in the 3-week-old group after 20 h, although lipid peroxidation did not change significantly. DON did not alter these parameters, only at gene expression level. Gene expression of phospholipid hydroperoxide glutathione peroxidase (GPX4) showed minor, but significant, changes in both age- and mycotoxin exposure groups. Glutathione reductase (GSR) showed a dual response for the mycotoxin exposure, which was not consequent in either age groups, or treatments. Glutathione synthetase (GSS) showed a decreasing tendency in the younger animals while in the older group elevating tendency was observed as effect of both mycotoxins. Time, treatment and their combined effect also showed relation with the changes in the parameters.
