Ergot alkaloid and ricinoleic acid contents of 63 ergot sclerotia samples from rye throughout Germany of the harvest years 2006-2009 were determined. Alkaloid contents were analyzed by means of high-performance liquid chromatography with fluorescence detection (HPLC-FLD) and ricinoleic acid contents

Ergot alkaloids are mycotoxins that are undesirable contaminants of cereal products, particularly rye. A method was developed employing clean-up by cation-exchange solid-phase extraction, separation by high-performance liquid chromatography under alkaline conditions and fluorescence detection. It is

Hydrothermal treatments are primarily used to increase the digestibility of nutrients and therefore to improve the feeding value of feedstuffs mainly for non-ruminants. Other positive side effects may occur, e.g. a decrease in toxicity of feed contaminated with mycotoxins. To study such effects, 4

An experiment with five litter-mate barrows showed that severe reduction in feed intake and growth rate accompanied the inclusion of either 1.0 or 2.0% ergot in the ration. Levels of 0.10 and 0.05% ergot allowed moderate feed intake and weight gain but not equal to the pig fed the ergot-free ration.
