There are given the experimental studying data of the influence of mineral additives of metionate selenium, metionate iodine, cobalt sulphate and chromium chloride on blood fat acid composition of cows in the initial period of lactation. It was found that inclusion of mineral supplements in the amount of 0.2 mg Se, J, Co, Cr / kg of dry matter to the diet of cows during the month increases in plasma the level of palmitoleinic and arachidonic acid, and within two months - only linolenic acid. A similar mineral supplement with 10 times higher of iodine metionatu content, will boost the level of palmitoleinic, linolenic and arachidonic acids in the blood of animals. Moreover, in the first months of feeding the concentration of more stearic and oleic acids increases, and in the second - linoleic acid. Inclusion of high mineral supplements to the cows diet, especially with higher iodine metionate content, increases the productivity of dairy cows and milk fat.
