| Outline of Final Research Achievements |
We investigated effects of a commercially available mycotoxin adsorbent (MA) using Zearalenone (ZEN) contaminated herd as a model herd. The results indicate that MA supplementation has beneficial effects in reducing ZEA absorption from the intestine of cattle, reversing hepatic effects. Additionally, our field trials revealed that 1) natural ZEN contamination resulting in urine levels below the threshold value does not affect embryo production in Japanese Black and Holstein cows undergoing superovulation, and 2) the monthly (seasonally) variation of urinary ZEN concentrations existing under the standard dairy farming condition. Moreover, the effects of in vitro exposure of porcine spermatozoa to ZEN were studied by evaluating several parameters of an in vitro fertilization (IVF) system. Overall, the results indicate that prolonged exposure of boar spermatozoa to ZEN up to 1000 μg/l under reduced metabolic conditions does not affect their in vitro function.
