Most often, the producers of mycotoxins are fungi of the genera Aspergillus , Fusarium , Penicillium and some others. The clinical symptoms of mycotoxicoses vary significantly, and lethal outcomes are possible. For this reason, the mycotoxicological study of various types of feed under production conditions is an indispensable component of veterinary support of industrial animal husbandry. As part of this study, a retrospective analysis of the results of a mycotoxicological study of feed for different animal species was carried out in the Omsk region in 2017-2021. All feeds received by the Omsk Regional Veterinary Laboratory for 5 years for the determination of mycotoxins were examined for the presence of ochratoxin A, zearalenone, T-2 toxin, aflatoxin B 1, deoxynivalenol. It was established that almost 70 % of the studied samples contained mycotoxins, including their maximum allowable level was exceeded in 74 samples. Exceeding the permissible levels was noted for the content of T-2 toxin (34 samples), zearalenone (27 samples), ochratoxin A (6 samples), aflatoxin B 1 (4 samples) and deoxynivalenol (3 samples). The largest number of cases of contamination was recorded in the study of feed and feed mixtures. The greatest danger is the multiple contamination of feed with mycotoxins. This increases the risk of developing comorbid conditions and the spread of opportunistic infections.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Микотоксины могут накапливаться в сырье растительного происхождения на разных технологических этапах его получения. Чаще всего продуцентами микотоксинов являются грибы родов Aspergillus , Fusarium , Penicillium и некоторых других. Клинические симптомы микотоксикозов существенно варьируют, при этом возможны летальные исходы. По данной причине микотоксикологическое исследование разных видов кормов в условиях производства - обязательный компонент ветеринарного сопровождения промышленного животноводства. Проведен ретроспективный анализ результатов микотоксикологического исследования кормов для разных видов животных в Омской области в период с 2017 по 2021 г. Все корма, поступившие за 5 лет в Омскую областную ветеринарную лабораторию для определения микотоксинов, исследованы на наличие охратоксина А, зеараленона, Т-2 токсина, афлатоксина B 1, дезоксиниваленола. Установлено, что почти 70 % исследуемых образцов содержат микотоксины, в 74 пробах был превышен их максимально допустимый уровень. Превышение допустимых уровней отмечено по содержанию Т-2 токсина (34 пробы), зеараленона (27 проб) охратоксина A (6 проб), афлатоксина В1 (4 пробы) и дезоксиниваленола (3 пробы). Наибольшее количество случаев контаминации регистрировали при исследовании комбикормов и кормосмесей. Наибольшую опасность представляет множественная контаминация кормов микотоксинами. При этом возрастает риск развития коморбидных состояний и распространения оппортунистических инфекций.</p></trans-abstract><kwd-group xml:lang="en"><kwd>mycotoxins</kwd><kwd>animal feed</kwd><kwd>ochratoxin</kwd><kwd>zearalenone</kwd><kwd>T-2 toxin</kwd><kwd>aflatoxin</kwd><kwd>deoxynivalenol</kwd><kwd>mycotoxicosis</kwd><kwd>comorbid conditions</kwd><kwd>opportunistic infections</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>микотоксины</kwd><kwd>корма для животных</kwd><kwd>охратоксин</kwd><kwd>зеараленон</kwd><kwd>Т-2 токсин</kwd><kwd>афлатоксин</kwd><kwd>дезоксиниваленол</kwd><kwd>микотоксикозы</kwd><kwd>коморбидные состояния</kwd><kwd>оппортунистические инфекции</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Работа выполнена в рамках гранта Президента Российской Федерации для государственной поддержки молодых российских ученых (МД-2435.2022.5).</institution></institution-wrap><institution-wrap><institution xml:lang="en">The work was performed under the Grant of the President of the Russian Federation for state support of young Russian scientists (MD-2435.2022.5.).</institution></institution-wrap></funding-source></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Gerunova LK, Gerunov VI, Kornejchuk DV.
