Summary. Industry-wide increase of hatching of chicks even by 1–2 % makes it possible to additionally get tens of millions of birds. Therefore, new highly biologically active preparations are searched for on a constant basis. In this regard, the study of influence of preparations which contain iodine is of particular scientific interest. It is known that this particular element is actively included in thyroid hormones, which are largely responsible for the processes of hatching and synchronization of mass hatching of chicks. We chose Klamin as a source of iodine. It contains this element in organic, easily accessible form. The study of thyroid status showed that in the experimental group the level of thyroxin in the blood serum of day-old young was larger than the control number by a factor of 1.3 (р<0.05), and that of triiodothyronine – by 20 %. Day-old chicks of an experimental batch evaluated higher scores systems "Pasgar" and "Optistart" compared with the control. Besides, in making an assessment of mass hatching of chicks it has been established that the process of hatching of species in the test group began 6 hours earlier and occurred more synchronously than in the control group. By the end of the 21st day of incubation (504 hours) almost all chicks (100 %) of the test group have hatched, and only 89.2 % of chicks of the control group have hatched by this time of incubation.

Keywords: chickens, Klamin, temperature, organic iodine, thyroid hormones, "Pasgar", "Optistart".
