Mycotoxins influence on cows homeostasis under intensive animal husbandry conditions

The purpose of the study is to determine the effect of mycotoxins on the biochemical parameters of blood and milk in cows under intensive livestock farming conditions. When conducting studies of feed for mycotoxins, it was revealed that at complex № 1 of the OJSC Lednevo breeding farm in the Vladimirov Region, contamination of feed with fungi was higher than at complex № 2. The difference in DON was (4.615 ± 0.088 versus 2.04 ± 0.072 ng/kg). A retrospective analysis of the climatic conditions of the region during the growing period of feed crops showed that the high degree of contamination of feed was possibly associated with weather conditions that contributed to the growth of mold and the formation of mycotoxins. In cows fed diets more contaminated with zearalenone and aflatoxins, there was a significant increase (P
