Abstract
Ruminal zearalenone (ZEA) degradation in “in vitro” digestion was examined in different variants using the Hohenheimer Gas Test. First, the mycotoxin degradation was measured using squeezed rumen fluid from solid digesta of the dorsal sack and free rumen fluid from the ventral sack, respectively. Then free rumen, fluid of the ventral sac was used with addition of concentrate and mixtures of concentrate with sun-flower oil and starch, respectively. Within 24 hours ZEA was degraded down to 63% and 49% of the initial concentration when incubated with solid and fluid rumen digesta, respectively. Using additives and rumen fluid concentrate for incubation, concentrate, concentrate with oil and concentrate with starch, respectively, a reduction of ZEA to 46, 56 and 37% of the initial toxin concentration was observed.
