Effect of Chelating Compounds of Microelements for Iodine Enrichment of Cow Milk

Abstract

This article discusses the problem of iodine deficiency and proposes a solution to this problem by enriching milk with iodine due to the use of organic compounds of microelements in diets of cows. The article presents the results of comparative study of inorganic and organic micromineral additives' influence on the content of iodine in milk and activity of thyroid hormones in the blood of cows. It has been established that the replacement of inorganic iodine (KI) with organic compound (OMEK-J, chemically iodized baker's yeast) increases iodine content in milk in 3-5 times. Similar effect has been observed for combination of inorganic and organic sources of iodine in 5:1 ratio with organic compounds of trace elements-metals (OMEK-Met, where Met-Fe, Co, Mn, Zn, Cu) being chelates with L-aspartic acid. Analysis of hormonal screening of the experimental cows' blood showed the positive correlation between the content of thyroid hormones-triiodothyronine and thyroxinein the blood and the content of iodine in the milk.

“…In particular, 14 microelements, such as ferrum, copper, manganese, zinc, cobalt, iodine, fluorine, chrome, molybdenum, nickel, strontium, silicon and selenium are necessary for the organism. They increase the activity of enzymes that catalyze (accelerate) biochemical processes, participate in the synthesis of carbohydrates, proteins and vitamins and also take part in the metabolism [12,13]. As it is known, microelements in the composition of herbal drugs contribute to their activity [14].…”
