One hundred two samples of feeds made in Lithuania, which included maize silage, grass-legume silage, hay and ensiled crimped maize were investigated during 2008-2012 for contamination with some mycotoxins. The highest concentrations of mycotoxins determined were those of deoxynivalenol (DON) – 471.0 μg/kg and aflatoxin B1 (AFB1) – 21.2 μg/kg in ryegrass silage from bales, and zearalenone (ZEA) – 625.0 μg/kg in maize silage from trenches. The present study has been carried out based on these data because animal feeds contaminated with mycotoxins can cause reduced productivity of dairy cows and health disorders in the long term. The aim of this study was to investigate the long-term exposure of toxic effects of a diet naturally contaminated with low concentrations of mycotoxins on milk composition and biochemical, hematological, immunological parameters of dairy cows and to determine the anti-mycotoxin effect of Mycofix Plus 3.E. Twenty eight clinically healthy, medium productive Lithuanian Red cows were selected. ZEA was a major contaminant found in the corn silage at concentration levels of up to 1000.0 μg/kg of dry matter. DON was the second major found in the hay at concentration levels of up to 600.0 μg/kg of dry matter. The highest concentration AFB1- 10.0 μg/kg was determined in ground barley. The Anti-Mycotoxin Additive (AMA) Mycofix Plus 3.E was given individually to 14 cows at a concentration of 40.0 g daily for 9 weeks. The present results indicate that feeds naturally contaminated with low concentration of mycotoxins produced by Fusarium spp. and Aspergillus spp. in a diet of dairy cows can have a negative influence on somatic cell count, blood parameters and immunity. The addition of an Anti-Mycotoxin Additive (Mycofix Plus 3.E) to diet of dairy cows can prevent many of these effects.
