Abstract

The purpose. To position the link between fat-acid content of tissues and productive attributes of honeybees at different amount of sunflower seed oil in feed additive. To determine replicated ability of queen bees and honey productivity of workers. Methods. Probe of breeding capacity of queens was spent according to F.A. Lavrekhin and S.V. Pankova procedure. Amount of the gained commodity honey they determined by method of weighting honey taken from honeycomb jacks before and after pump down. In feed additive and tissues of honeybees they determined presence and content of fatty acid of common lipids using method of gas-liquid chromatography (I.F. Rivis with co-authors). The content of fatty acids of common lipids in feed additive and probed tissues of bees they determined by method of extraction of lipids by chloroform-methanol mixture. Results. Feeding of feed additive, enriched with sunflower seed oil in amount of 10 and 20 g essentially increased concentration of saturated, monononsaturated and polynonsaturated fatty acids of common lipids in tissues of abdomen, chest and head of honeybees of the Ist and especially the IInd probed groups. It testified to substantial growth of security of tissues of honeybees with power and structural materials. Thus in probed tissues of bees the ratio of content of polynonsaturated fatty acids of family u-3 (linolenic row) to polynonsaturated fatty acids of family --6 (linolic row) was diminished. Conclusions. Changes in fat-acid content of tissues of abdomen, chest and head of honeybees of the Ist and especially the IInd probed groups were accompanied by changes of breeding capacity of queens and honey productivity of workers. In particular at queens of these groups grew ovi-production, and at workers — honey productivity.
