The inadequacy of mineral nutrition leads to inhibition of physiological and metabolic reactions in the body of honeybees. It is known that Cobalt chloride is used to activate oviposition of the queen bee. It was established that Cobalt and Nickel citrate, obtained by the method of nanotechnology, corrects the mineral metabolism and affects the metabolism of bees. It is known that Cobalt plays an important role in the work of enzymes; synthesis of vitamin B12, promotes assimilation of vitamins A, E, C; increases protein metabolism, participates in hematopoiesis. Nickel also has a pronounced effect on hemopoiesis, namely on the morphological composition of blood. But its effect on the cell and subcellular level is not well understood. The results of studies of the effect of soybean flour with the addition of Cobalt and Nickel citrates on the content of mineral elements in the tissues of the body of bees and honeycombs are given. The research was carried out in the farms in the Lviv region, in April-May at the bees of the Carpathian breed. It was established that the content of Ferrum, Cuprum and Germanium in the tissues of bees increases with the addition of soybean flour with Сobalt citrate at a dose of 2 mg per 500 g of soy flour. When Nickel citrate was added to the feed at a dose of 1 mg per 500 g of soy flour, the content of Ferrum and Cuprum increased in honeycombs. The complex combination of Citrits Co and Ni, soy flour with sugar syrup was characterized by a decrease in the level of Zn in the tissues of the bees compared to its contents in the control group samples. In samples of biological material, the content of Сobalt, Nickel and the essential elements Cuprum, Zink, Ferrum, Selenium, Germanium was determined by atomic emission spectrometry with inductively coupled plasma. Citrates of the microelements were produced by the method of M. Kosinov and V. Kaplunenkо.
