EVALUATION OF THE TOXINOGENOUS POTENTIAL OF THE FUSARIUM GRAMINEARUM STRAINS ISOLATED FROM THE COMPOUND FEEDS FOR PIGS

Abstract

Fusarium graminearum is a species of fungi with a wide geographical dispersal area which produces type B trychothecenes (deoxynivalenol mainly) and zearalenone. This species contaminates the cereals, corn mainly, the main ingredient for compound feeds.The mycotoxins produced by Fusarium graminearum (deoxynivalenol and zearalenone) produce intoxications, severe sometimes, in animals of economic interest, the pigs being the most sensitive to their action.The paper aims to evaluate the capacity of Fusarium graminearum strains isolated from compound feeds for pigs to produce deoxynivalenol and zearalenone.The study shows that 80% of the surveyed strains can produce deoxynivalenol in concentrations of 1.80-198.4 μg/g, and 66.66% produce zearalenone in concentrations ranging between 0.25-564.2 μg/g.
