Currently, the presence of toxins in the composition of all feed for cattle is recorded as a result of a violation of the technology of harvesting and storing feed. The most famous are aflatoxins, ochratoxins, zearalenone, T2 toxin, deoxynivalenol (DON), fumonisin, which, getting into the blood of an animal, quite negatively affect the body of cows, reducing their productivity and fertilizing ability. Of particular importance is the determination of toxins in feed when feeding highly productive livestock under conditions of intensive milk production technology. The purpose of the work is to establish the degree of influence of different dosages of feed sorbents on the productive and reproductive qualities of cows. The studies were carried out in the conditions of the breeding reproducer of the black-and-white breed LLC Barmino in the Nizhny Novgorod region. The objects of research were cows of the first lactation of the Black-and-White breed, but the subject of research was the milk productivity of animals and the efficiency of insemination of cows. It was found that milk productivity and higher rates of reproductive abilities were the best in cows of the third experienced groups that received the largest amount of feed sorbent - 2 kg per ton of concentrated feed.
