Abstract
The use of various animal feed additives for training and for inhibiting age-related decline in brain activity increases every year. The most interesting are biologically active substances that improve the normal functions of the body. Many of these tools also help to reduce the negative effects of ecotoxicants, the level of which in the environment is constantly increasing. In a fourmonth experiment on white rats, the effect of the feed additive Phytodoc neuro was studied at using at a therapeutic dose (4 g/kg of feed) and exceeding it by 3 and 5 times (12 and 20 g/kg of feed). Upon receipt of the drug in the therapeutic dose, negative changes were not detected. On the contrary, in the fourth month of the experiment, there was a significant increase in the content of immunoglobulins in the blood serum. An increase in the amount of hemoglobin and leukocytes was noted, which can be explained by the effect of amino acids on the metabolism of animals.
