aref2 A complex preparation of Gumiton, enriched in iodine, was developed. Studies were conducted to examine its influence on the health and milk productivity of lactating cows. A scientific and economic experiment was set up under conditions of CJSC "Dubrovskoe" of Kozhevnikovo area of the Tomsk region. For the experiment two groups of ten lactating cows were formed on a pair-analogues principle. Animals from control group were fed by potassium iodide in the quantity necessary for elimination of iodine deficiency - 11 mg per a head in a day. Experimental animals were fed by Gumiton, enriched in iodine, with the concentration of microelement 200 mg/g, 55% of it was in organic form, at the dose 0.1 mg/kg of live weight. The concentration of iodine in the preparation was designed to eliminate its deficiency (which is 79-80% in the current type of feeding at the farm) when it was fed in the suggested dosage. Usage of the studied preparation increased the milk productivity of cows compared to control by 9.72%, fat content of milk - by 0.14%, the profitability of production - by 3.04%.
