Iodine belongs to the vital trace elements, without which the normal functioning of the animal body is impossible. Currently, potassium iodide is mainly used in animal feeding, which is an unstable compound that decomposes during the preparation and storage of premixes and compound feed. Organic iodine, which is in a chemical bond with any organic substance has already been adapted for the animal’s body and is absorbed much better than inorganic. Also, organic iodine has a high chemical stability. SATURAN J is a feed additive for farm animals the main active ingredient of which is iodine in the organically bound form. In our case, iodine is imposed on sunflower oil. Auxiliary substances are corn porridge, corn groats and sunflower oil. Cows of the 1st experimental group were additionally fed the additive in the amount of 16,5 g/head/day, the 2nd experimental group with 27,5 g/head/day. The SATURAN J additive was fed once a day during morning feeding. There was the increase in milk productivity in the 1st experimental group by 16,3 %, and in the 2nd group by 20,1 %, compared with the control group when the input of the feed additive SATURAN J. There was also the increase in the mass fraction of milk fat. When converted to 4 % milk the difference has been increased even more and amounted to 25,6 and 35,3 %, respectively, in the experimental groups. The inclusion of SATURAN J feed additive in the ration of cows in the amount of 16,5 and 27,5 g/head/day allowed to stabilize the hormonal background of animals, increase quantitative and qualitative indicators of productivity, as well as to receive additional revenue in the amount of 16 597,8 and 21 714,9 rubles per 1 cow, respectively, in experimental groups.
