Influence of selenium-containing preparations on cow's milk with increased technogenic load on agrosystems

Feeding experimental animals with supplements containing selenium in various forms and doses did not have a significant effect on milk productivity and the qualitative composition of milk. However, when using «Sel-Plex», there is a tendency to increase the average daily milk yield in terms of basic fat content by 0.9-4.4 % and an increase in the protein content in milk by 1.2-2.3 % compared to control.
