Wirkung von Deoxynivalenol beim wachsenden Schwein in Abhängigkeit von der Darreichungsform

To evaluate the minimum effective dose of pure DON leading to measurable losses in weight gain and feed consumption a special feeding experiment was created to compare the effect of DON in natural contaminated wheat and - for the first time - a non-cereal diet (potato) spiked with pure DON. Examined parameters were weight gain, feed consumption and blood parameters.Three trials were conducted. In the first trial a concentration of 4000 µg DON/kg feed was used. In the second and third trial we used concentrations of 4000 and 6000 µg DON/kg feed. Severe effects on feed consumption and weight gain were found only in the second trial (naturally contaminated wheat ad lib.). By contrast, no differences in any parameter were found in the first (restricted feeding) and third trial (non-cereal diet spiked with pure DON ad lib.).
