| Popis: | In this study, fungal contamination was determined as well as total aflatoxin B1(AB1), ochratoxin A (OTA) and zearalenon (ZEA) levels in corn-based feed samples obtained from four different farms in Serbia (n=35) during one year. Mycotoxins were detected in feed using the VICAM fluorometric method. It was determined that 97.14% of all samples were contaminated with moulds which belonged to following genera: Absidia, Acremonium, Aspergillus, Cladosporium, Geotrichum, Eurotium, Fusarium, Mucor, Mortierella, Oidiodendron, Penicillium, Rhizopus, Scopulariopsis, Syncephalastrum, Trichoderma, Ulocladium and Wallrothiella. A total of 58 different species were identified. Total mould count per 1 g ranged from 1.00 log cfu/g (dried corn silage - autumn, fresh corn silage - summer and corn grain silage - spring) to 7.32 log cfu/g (dried corn silage - winter). Mycotoxins were isolated from 28.5% of samples: ZEA was found in summer (220-240 ?g/kg) and in spring (240 ?g/kg) in concentrate samples; OTA was detected in winter in dried corn silage (16 ?g/kg) and in spring (12 ?g/kg); all samples were AB1 free. |
