Mycotoxins are a consequence of mold growth. Fungi produce mycotoxins under conditions of changing tem-perature, humidity or aeration, as well as in the presence of aggressive agents. The problem of mycotoxicosis is cur-rently relevant. It has been proved that the use of the mycotoxin adsorbent Novazil Plus in cow diets helps to reduce the effect of mycotoxins on the animal body, which is expressed by the most optimal processes of ruminal digestion, the optimal ratio of volatile fatty acids, an increase in the total number of microorganisms by 8.15-9.54%, as well as an increase in the productivity of cows with simultaneous improvement of quality indicators, in particular, a decrease in the concentration of Mycotoxin Aflatoxin M1 in milk. The use of the Best-Sil bioconservative contributed to improving the quality characteristics of the finished silage, reducing the accumulation of mycotoxins in it, and feeding such silage to cows also contributed to obtaining products of higher quality.
