Abstract
The content of total lipids and redistribution of their individual classes in the residual yolk of embryos has been established according to the additional introduction of a separate and complex of vitamins A, D3 and E in the diet of geese during the breeding season. It is shown that the addition of a complex of vitamins A, D3 and E, from an overdose of tocopherol in the diet of geese is optimal to stabilize the individual processes of lipid metabolism. It is shown that the residual yolk embryos observed increase in the content of phospholipids and related cholesterol to reduce background levels of free cholesterol and free fatty acids that corresponds to a reduction ratio of the level of cholesterol/phospholipid indicates the viscosity change with the viscosity membranes in a liquid phase and an increase in antioxidant activity. Also, there are changes in the fatty acid composition of residual yolk embryos. Observed decrease in the content of palmitic (С16:0), palmitoleic (С16:1) and oleic (С18:1) acids, with a parallel increase in levels of linoleic (С18:2), arachidonic (С20:4), eicosapentaenoic acid (С20:5), docosapentaenoic (С22:5) and docosahexaenoic (С22:6) acids. This, in turn, corresponds to an increase in the index are not saturated fatty acids, raise the level of activity confirms the antioxidant system and shows a stabilizing effect of the introduction of complex vitamins A, D3 and E on Δ6- and Δ5-desaturase activity. Attention should be paid also to reduce the content of diene conjugates and TBA-active products in the residual yolk embryos under the influence of the additional introduction of a complex of vitamins A, D3 and E, with high-dose tocopherol, compared with a control group.
