| Summary: | This investigation was conducted to determine the levels of aflatoxins, ochr'atoxin A and zearalenone in feeds and feedstuffs obtained from various regions of Turkey.<p>
Samples were analysed by thin layer chromatography. In this method, mycotoxinis were extracted with chloroform from materials and then tranfered through the sep-pak cardrige coloumn to elute the mycotoxins residues.<p>
Mycotoxins were found in the nine samples of a hundred materials analysed. Aflatoxin B! in two samples, ochratoxin A in five samples and zearalenone in three samples were determined. The average concentrations of aflatoxin B<sub>1</sub>, ochmtoxin A and zearalenone were 3.75., 12 and 6,6 microgram/kg respectively. The detectalble limits were 1 microgram/kig for aflatoxin, 2 microgram/kg for ochratoxin A and 4 microgram,/kg for zearalenone.<p>
According to results, the levels mycotoxins determined in the samples will not cause an extremely cases, however would make residue problems with consumption of these feeds ;by the animals for a long periods. |
