Abstract Female pigs respond sensitive both to DON and ZEN with anorexia endocrine disruption, respectively, when critical diet concentrations are exceeded. Therefore, the frequent co-contamination of feed by requires their parallel inactivation. The additive ZenA hydrolyzes while SBS inactivates through sulfonation. Both supplements were simultaneously added ( + , 2.5 g 100 U ZenA/kg) a control (CON−, 0.04 mg < 0.004 ZEN/kg; CON+, 0.03 ZEN/kg) Fusarium toxin contaminated (FUS−, 2.57 0.24...

Glyphosate (GLY) is worldwide one of the most used active substances in non-selective herbicides. Although livestock might be orally exposed via GLY-contaminated feedstuffs, not much known about possible hepatotoxic effects GLY. As hepatic xenobiotic and nutrient metabolism are interlinked, toxic GLY residues influenced by supply. Therefore, a feeding trial with lactating dairy cows was conducted to investigate feedstuffs different concentrate feed proportions (CFP) diets as tool for varying...

Glyphosate (GLY), the active substance in non-selective herbicides, is often found ruminant feed. The present feeding study aimed to investigate effects of GLY-contaminated rations and different concentrate feed proportions (CFP) on health fattening German Holstein bulls. Bulls were grouped by low (LC) or high (HC) CFP with (GLYLC, GLYHC) without GLY-contaminations (CONLC, CONHC) their rations. Intakes (dry matter, water) body weight documented continuously lasting over an average range from...

Maternal exposure to various stimuli can influence pre- and postnatal development of the offspring. This potential has been discussed for glyphosate (GLY), active substance in some non-selective herbicides. Accordingly, present study investigated putative effects GLY residues rations on cows their Dams received either GLY-contaminated (GLY groups) or control (CON combined with low (LC high (HC concentrate feed proportions (CFP) 16 weeks during mid- late lactation early gestation (59±4 days...

The sensitivity of pigs to deoxynivalenol (DON) might be increased by systemic inflammation (SI), which also has consequences for hepatic integrity. Liver lesions and a dys-regulated gene network hamper handling elimination DON whereby the way initiation play an additional role. First second-pass exposure liver with LPS triggering SI was achieved infusion via pre- or post-hepatic venous route, respectively. Each group pre-conditioned either control diet (0.12 mg DON/kg diet) DON-contaminated...
