Peculiarities of seasonal mycotoxin contamination of raw grain and mixed fodders in Krasnodar region

Koshchaev A. G., Khmara I. V.

Summary. As a result of the conducted monitoring of mycotoxins in raw grain by season at poultry farms of Krasnodar region authors revealed six mycotoxins. Authors also studied the natural contamination level of the main types of grain forages. Frequency of contamination varied considerably from 26% to 69%, while the overall trend by years of research did not changed significantly. In analyzing the data on the detection rate of mycotoxins in feed samples by season authors found that studied mycotoxins are detected during the whole year, at the same time zearalenone and deoxynivalenol were more commonly found in the samples analyzed during winter period, T-2 toxin and ochratoxin A – in spring, fumonisin B1 and aflatoxin B1 – in summer. During the study authors proved that the concentration of mycotoxins does not depend on weather and climatic conditions of the year, but it is characterized by seasonal variability, and its variability is affected by the season.

Key words: mycotoxins, mixed fodder T-2 toxin, zearalenone, fumonisin B1, ochratoxin A, aflatoxin B1, deoxynivalenol.
