Effects of Zearalenon and Deoxynivalenol on reproduction and immunology in mares

Abstract

The metabolism of ZON has already been investigated in many species. The swine and the heifer differ in ZON metabolite production (Zöllner et al. 2002). In the heifer an epimeric Zearanal is produced, probably because of the rumen flora. In this project it will be investigated if this and other metabolites are produced in the horse, that also is a herbivore. The proportion of glucuronidised and non glucuronidised ZON-metabolites in the serum and their elimination way via feces or urine is still unknown by now and will be investigated. Furthermore DON is known to be de-epoxidised via adapted gut flora in the pig (Hedman u. Pettersson 1997), and this study will investigate whether DON metabolites are treated the same way in the horse.
