Abstract
The paper focuses on possible effects of the botanical composition and weather conditions on the extend of zearalenone and ochratoxin A concentrations in various grass swards in winter pasture systems. Zearalenone is only detectable in pure stands ofLolium perenne or inLolio-Cynosuretum plant communities, respectively. The occurrence of ochratoxin A is more frequent and less specific concerning the botanical composition. This mycotoxin was found in both,Lolium perenne andFestuca arundinacea in varying years. The incidence of ochratoxin A depends on year and is apparently related to the weather conditions in autumn and winter. There was no evidence that particular locatio8/22/2008 12:57PMns have a higher or a lower risk for high ochratoxin A or zearalenone concentrations than others. Peak values in individual swards are not intermittent over the years.
