Effect of biological preparations on antioxidant animal status

The level of selenium in feed is highly dependent on its content in the environment: soil and water. In areas where the soil is poor in selenium, its deficiency is more often observed in humans and animals. Such areas include the territory of the Chuvash Republic. Therefore, the use of selenium-containing biological products, in conditions of selenium deficiency, in correcting the physiological status of animals is very important. We have studied the influence of the domestic selenium-containing biological preparation "Selenopyran" and the immunomodulator "Polistim" on the blood parameters of bulls in the conditions of the Chuvash Republic. The research results indicate that biological preparations have a stimulating effect on the immuno-hematological and biochemical parameters of the blood.
