Abstract
The study was conducted on honey bees of the Carpathian breed on the basis of the apiary of S. Z. Gzhytskyi Lviv National University of Veterinary Medicine and Biotechnologies. The bees were kept in 8-frame beehives with size of the frame of 435 × 300 mm. The study was undertaken in the summer-autumn period. A total of 5 groups of bee families were formed according to the analogue principle, with three families of bees in each group. Control (I) group received sugar syrup in 1 : 1 concentration (1000 mL/group/week). In the experimental (II) group, Ag was added to the syrup in amount of 0.5 mL/g of the sugar syrup; in III experimental group – in similar conditions Ag was added in 1 mg/L amount; IV group received sugar syrup with Cu in 0.5 mg/L amount; V experimental group – Cu in amount of 1 mg/L of sugar syrup. Microelements were added to sugar syrup in the form of citrates obtained using method of nanotechnology, developed by the company Nanomaterials and Nanotechnologies in Kyiv. The period of monitoring lasted 28 days with 7 days interval of preparation. Inter-group and anatomic differences were found in content of certain mineral elements in the tissues of the head, thorax and abdominal sections of the honey bees in conditions of feeding with citrates of argentum and cuprum in sugar syrups. Under the influence of citrate of argentum in amount of 0.5 and 1.0 mg/L of sugar syrup, content of ferrum increased in the tissues of the head and abdominal sections, though it decreased in the thorax, content of cuprum decreased in the tissues of head, thorax and abdomen, content of zinc increased in the tissues of head and thorax, though it decreased in the abdomen, content of lead and cadmium reduced in the tissues of all anatomic sections of the organism of honey bees. Under the influence of cuprum in amount of 0.5 and 1.0 mg/L of sugar syrup, content of ferrum reduced in the tissues of the head, though it increased in the tissues of thorax and abdomen, content of cuprum increased, and the content of zinc, lead and cadmium reduced in the tissues of all anatomic sections of honey bees. According to the results of the study, the determining effect of feeding of honey bees on the optimization of the parameters of mineral metabolism in different anatomic sections of the organism of bees is discussed.
Highlights
Using modern methods of maintaining and care of bee families, the issue of their rational provision with nutrition arises
It should be noted that feeding sugar syrup with both 0.5 and 1.0 mg/L of argentum in the form of citrate was characterized by increase in the content of ferrum in homogenate of the tissues of the head of honey bees from In the experimental (II) and III groups compared to the control group (Fig. 1)
The high content of cuprum in the tissues of the abdominal section of the organism of honey bees which received 1 mg of cuprum had an obvious dependence on the dose of consumed additives and was highest compared to other anatomic sections
Summary
Using modern methods of maintaining and care of bee families, the issue of their rational provision with nutrition arises. For normal vitality and reproduction, a bee family, regardless of period of season, should receive food with proteins, fats, carbohydrates, mineral salts, vitamins and water (Tyshhenko, 1986; Lebedev & Bilash, 1991; Kovalchuk & Fedoruk, 2008). For intensive concentration of strength in spring, consuming protein-containing fodders is one of the most important factors for bee families. For the development and functioning of mandible and pharyngological glands which produce components of royal jelly for feeding larvae, bees should consume complete protein fodder A number of studies (Bogdanov et al, 2007) indicate that clinical condition, resistance, productivity and quality of products, reproductive function of humans and animals completely depend on provision of their organism with biologically active substances, including microelements. One of the leading methods of increasing resistance of bee families to negative external factors (Conti & Botre, 2001) and, as a result, ecological safety of the products of beekeeping is using mineral complexes
