EFFECT OF THE COMPLEX IODINE-SELENIUM-CONTAINING PROPHYLACTIC PREPARATION “IODIS-VET” ON THE IMMUNOLOGICAL PROPERTIES OF COLOSTRUMAND MILK PRODUCTIVITY OF COWS

Abstract

The importance of microelements and vitamins in animal nutrition is extremely high, only with their sufficient amount the animal body is able to fully use the nutrientsin the feed, maintain health and give the maximum productivity. We have established the positive effect of the complex iodine-selenium-containing prophylactic preparation “Iodis-vet” on the immunological properties of colostrum and milk productivity of cows in the interlactation period. The studied preparation also contributes to the increase of average daily milk yield. The best results were obtained when using it at a dose of 125 ml per head per day. The mass fraction of protein increased by 3.4%, the amount of immunoglobulins - by 8.04%, the milk yield for the entire period of lactation - by 7.09%.
