The in vitro effects of deoxynivalenol (DON), de-epoxy-DON, DON-sulfonate (DONS) and sodium metabisulfite (Na(2)S(2)O(5), SBS) on porcine peripheral blood mononuclear cells (PBMC), and on the Intestinal Porcine Epithelial Cell lines IPEC-1 and IPEC-J2 were examined by using the MTT assay. In addition, an uncontaminated and a DON contaminated triticale were(More)
Eleven castrated male pigs weighing 88.1 +/- 3.9 kg on average were adapted to a diet containing DON (4.2 mg DON/kg) over a period of 7 days. Feed was given restrictively with 1.1 kg per meal (two meals per day). On the day of measurement, all pigs were slaughtered at different time intervals following the morning meal containing DON (1, 2, 3, 4, 5, 6, 8,(More)
The Fusarium toxin deoxynivalenol (DON) often co-occurs along with the acetylated derivatives 3-acetyl-DON and 15-acetyl-DON in diets for ruminants. De-epoxy-DON is formed by rumen micro-organisms, while the acetylated DON derivatives might also undergo ruminal metabolism with de-epoxy-DON as an end product. However, despite the fact that de-epoxy-DON is(More)
A dose response study was carried out with piglets to examine the effects of increasing amounts of Fusarium toxins in the diet on performance, clinical serum characteristics, organ weights and residues of zearalenone (ZON) and deoxynivalenol (DON) and their metabolites in body fluids and tissues. For this purpose, Fusarium toxin contaminated maize (1.2 mg(More)
A simple in vitro system was developed to study the efficacy of commercially available mycotoxin detoxifying agents and adsorbing substances as feed additives to detoxify deoxynivalenol (DON) and zearalenone (ZON) in situ. The in vitro model simulates the conditions (pH, temperature and transit time) of the porcine gastrointestinal tract, as pigs react most(More)
A method for the determination of deoxynivalenol (DON) and its metabolite de-epoxy-deoxynivalenol (de-epoxy-DON) in blood serum, urine, faeces/digesta and bile fluid is described. Liquid samples (urine and bile after incubation with ß-glucuronidase) were extracted with ethyl acetate on a ChemElut column. Freeze dried faeces and digesta were extracted with a(More)
The aim of this study was to examine the effects of a control diet (CON) or a Fusarium toxin contaminated diet (FUS) with and without HS (CON-HS and FUS-HS, respectively) on pigs during a 10-week growth trial starting at 35.1±3.2 kg live weight (n=12/group). Moreover, 2 additional choice feeding groups were included to test the ability of the pigs to(More)
1. A growth experiment was carried out with male broilers from d 1 to d 35 of age in order to evaluate the effects of the addition of a detoxifying agent (Mycofix Plus, Biomin GmbH, Herzogenburg, Austria) at different dietary proportions of wheat (0, 16.5, 33, 49.5 and 66%) contaminated with Fusarium mycotoxins (21.2 mg of deoxynivalenol and 406 microg of(More)
Fusarium toxins are of great practical relevance in animal feeding since they may occur in toxicologically relevant concentrations. Therefore, many attempts have been made to find ways to detoxify contaminated feedstuffs or diets in order to cope with the problem. The supplementation of contaminated diets with detoxifying agents seems to be easily feasible,(More)
A dose response study was carried out with pigs in order to examine the effects of increasing dietary deoxynivalenol (DON)-concentrations on performance, clinical serum characteristics, nutrient digestibility and DON-metabolism. For this purpose, wheat contaminated naturally with Fusarium toxins was incorporated into pig diets at increasing proportions to(More)
