Romaniv L. Lipids and trace elements in tissues and products of bees and their performance under feeding by soybean meal and chromium compounds

The thesis deals with the study of physiological and biochemical peculiarities of the impact of natural and transgenic soybeans meals and Cr chloride and citrate under conditions of their use in the spring and summer-autumn feeding on lipid and mineral metabolism in the body of honeybees, the content of lipids and minerals in their products and the reproductive ability of queen bees. The lipid metabolism and the content of certain trace elements in tissues and products of bees under the influence of feeding with meal from native and transgenic soybeans have been studied for the first time. The correlation between lipid classes and trace elements in tissues and bee products under conditions of feeding by native soybeans meal and Сr compounds has been established. The peculiarities of lipid and trace elements metabolism in tissues and different anatomical parts of the bees, the content of these substances in their products have been elucidated. The methods of use of soybean meal and Cr compounds in bee's nutrition have been developed. The proper amounts which correct biological activity of chromium chloride and also citrate obtained by nanobiotechnology methods have been determined and tested in feeding of honeybees. The influence of Cr (III) on the metabolism of lipids and certain trace elements in body tissues and its the content in products has been shown.
