Summary. Mycotoxins exert a negative effect on large horned cattle through a decrease in feed intake. Extreme drought conditions during the cultivation and harvest of crops included in the diet of cows can lead to a dangerous increase in the concentration of aflatoxin B1, a highly toxic and carcinogenic substance from the group of mycotoxins from microscopic fungi Aspergillus, mainly Aspergillusflavus and Aspergillusparasiticus. As a result, milk will be contaminated with aflatoxin M1 (AFM1). In LLC AF Khutorok Timashevsky District Krasnodar Territory in an experiment on dairy cows with the inclusion of aflatoxin B1 (AFB1) contaminated feed in the diet, established the minimum dose of aflatoxin B1 in feed in the amount of 2 mg / head per day. The minimum amount of aflatoxin B1 in the diet caused the appearance of a secondary metabolite - aflatoxin M1 in cow's milk. Aflatoxin M1, formed in the body of dairy cows by a metabolic route from aflatoxin B1 introduced with food, was excreted in milk for 72 hours. It was found that with the addition of a broad spectrum mycotoxin adsorbent based on glucans of the cell wall of yeast and algae to the diet, the AFM1 content in milk decreased (on average by 60%). In addition, when this adsorbent was added to diets, the average level of AFM1 in milk was 3 times lower compared to the control. The rate of excretion of AFM1 from the body of cows was determined. Its maximum amount of 0.15800 mcg / kg was excreted in milk during the third day from the last summer AFV1. When storing grain fodder, the content of mycotoxins should be determined and a constant analysis should be carried out according to microbiological safety indicators.
