A dose-response study was carried out to examine the carryover of zearalenone (ZEN), deoxynivalenol (DON) and their metabolites into bovine milk. Therefore, a feeding trial with 30 dairy cows fed with three different levels of Fusarium (FUS) toxin-contaminated maize was performed. A control group (0.02 mg ZEN kg(-1) dry matter (DM) and 0.07 DON kg(-1) DM)(More)
The systemic effects of the Fusarium toxin deoxynivalenol (DON) and of bacterial lipopolysaccharides (LPS) were studied in male castrated pigs (40.4 ± 3.7 kg) infused intravenously with either DON or LPS alone (100 μg DON/kg/h, 7.5 μg/LPS/kg/h), or together (100 μg DON plus 7.5 μg/LPS/kg/h). The Control group received a saline infusion (n=6/treatment, 24h(More)
The control of mycotoxins is a global challenge not only in human consumption but also in nutrition of farm animals including aquatic species. Fusarium toxins, such as deoxynivalenol (DON) and zearalenone (ZEN), are common contaminants of animal feed but no study reported the occurrence of both mycotoxins in fish feed so far. Here, we report for the first(More)
Infrared imaging proves to be a quick and simple method for measuring temperature distribution on the pig's head. The study showed that infrared imaging and analysis with a difference ROI (region of interest) method may be used for early detection of elevated body temperature in pigs (> 39.5°C). A high specificity of approx. 85% and a high sensitivity of(More)
The in vivo effects of the Fusarium toxin deoxynivalenol (DON) on albumin and fibrinogen synthesis in pigs and metabolic activity of porcine peripheral blood mononuclear cells (PBMCs) were studied alone or in combination with lipopolysaccharides (LPSs) in order to examine proposed synergistic effects of both substances. A total of 36 male castrated pigs(More)
Physiological consequences of adaptation to and continued feeding of a high-energetic diet were studied in eight non-pregnant, non-lactating dairy Holstein cows over a period of 16 weeks. The first six weeks served as an adaptation period from the low energetic straw-based diet (3.8 MJ NEL/kg DM) to the high-energetic ration (7.5 MJ NEL/kg DM). Intake of(More)
We studied the interaction between deoxynivalenol (DON)-feeding and a subsequent pre- and post-hepatic immune stimulus with the hypothesis that the liver differently mediates the acute phase reaction (APR) in pigs. Barrows (n = 44) were divided into a DON-(4.59 mg DON/kg feed) and a control-diet group, surgically equipped with permanent catheters pre- (V.(More)
Previous studies have shown that chronic oral deoxynivalenol (DON) exposure modulated Escherichia coli lipopolysaccharide (LPS)-induced systemic inflammation, whereby the liver was suspected to play an important role. Thus, a total of 41 barrows was fed one of two maize-based diets, either a DON-diet (4.59 mg DON/kg feed, n = 19) or a control diet (CON, n =(More)
We investigated a proposed synergistic effect of deoxynivalenol (DON) and lipopolysaccharides (LPS) on small intestinal architecture and epithelial barrier integrity in pigs. Crypt depth and intestinal cell proliferation were analyzed, as well as expression of zonula occludens protein-1 (ZO-1) and β-catenin of the apical junction complex along the small(More)
Concentrations of zearalenone (ZEN), deoxynivalenol (DON) and their metabolites α-zearalenol (α-ZEL), β-zearalenol (β-ZEL), zearalanone (ZAN), α-zearalanol (α-ZAL), β-zearalanol (β-ZAL) and de-epoxy-deoxynivalenol (de-DON) in serum, liquor and urine of female piglets fed diets containing 0.01, 0.05, 0.08, 0.17 and 0.29 mg ZEN/kg and 0.03, 0.59, 1.27, 2.01(More)
