Abstract
In science vicasol is known to be relative to the energy and antioxidant systems of tissues closely related to the biosynthesis and oxidation of fatty acids. This effect may cause changes in the fatty acid composition of tissues, and numerous works on the positive effect of quinones and their derivatives on the myocardial function, suggest that the proper dose and feeding can increase the stability and productivity of poultry. The given was aims to study the effect of vicasol on the fatty acid composition of goose myocardium.
 Myocardium was chosen as a biological object. Biological material was collected every 7 days throughout the period from the 21st to the 35th day of ontogeny, characterized by the state of physiological tension of geese. Feeding of geese with vicasol at a dose of 0.7 mg / kg body weight began with the 3rd day of ontogeny. Fatty acid analysis in myocardial tissues was performed by gas-liquid chromatography, pre-fabric samples were processed with the method by Palmer (1971) to obtain tissue lipid extracts.
 According to the results of the study, due to various changes in the content of the entire spectrum of fatty acids of the tissue during the experiment - the use of vicasol causes a slight increase in the unsaturation and the total content of unsaturated fatty acids in the myocardium of geese. These fluctuations are realized depending on the physiological state of the body. where vicasol can stimulate both the biosynthesis processes of individual fatty acids and their mitochondrial and microsomal oxidation, as evidenced by multidirectional reliable changes in the content of their entire spectrum. In particular, on the 21st day, the content of docosopentaenoic acid increased by 36.3% whereas the content of docosohexaenoic and linolenic acids decreased by an average of 21–24%, on the 28th day the content of eicosatetraic and docosahexaenoic acids increased whereas the content of the linoleic acids dropped by 22.6% in control groups. On the 35th day, the content of basic unsaturated fatty acids: palmitooleic, linoleic, linolenic and docosohexaenoic acids increased in the tissue under the influence of vicasol with complete depletion of docosopentaenoic acid. These fluctuations in fatty acid composition cause a slight increase in the total content of unsaturated fatty acids and increase the unsaturation of myocardial lipids on the 28th and 35th days of ontogeny of geese. Based on previous results regarding the antioxidant state of myocardium affected by vicasol and the given findings, which prove changes in the content of the entire spectrum of fatty acids during the selected ontogeny, vicasol can be used in poultry farming as a tool to improve the quality and the resilience of poultry.
