The article presents the results of study on the iodine aqua citrate impact on metabolism and productive qualities in piglets from ablactation to intensive feeding (29–70 days). Complete feed with gramineous group of concentrated feed of domestic production (Polissia area of Volyn) was used. Iodine content in the form of potassium iodide in premix to prestarter and starter compound feed of control group was 0.80 and 1.50 mg/kg respectively. We included iodine aqua citrate (made using nanotechnologies of Avatar Scientific and Production Company, LLC) into the diet of 1^st and 2^nd experimental group animals at the rate of 50 % and 25 % from the level of bioelement in premixes in KJ form.

It has been established that iodine with its extensive bioavailability as aqua citrate has a stimulating impact on metabolic processes in piglets. In particular, replacement of the recommended dose of inorganic iodine in premix with its citrate nano formulation promotes body weight increase in animals of the experimental group by 5.5 % (P<0.025) and 9.6 % as compared to analogs of the experimental group. Under such conditions hemoglobin, RBC and WBC levels in blood serum were in inverse proportion to levels of iodine consumed in its citrate form, which attests to enhanced levels of body defenses. At the same time, enhanced concentration of protein bound iodine and thyroid hormones have been detected in blood of experimental group piglets, which was stipulated by optimization of thyroid hormonegenesis. Experimental group piglets as compared to control had their levels of total blood protein unchanged yet with characteristic increase of globulin protein fraction levels by 4.1 and 5.9 %, respectively (P<0,05) and urea concentration as well as decrease of excess nitrogen and glucose levels.
