Abstract

Infectious diseases are a significant problem in poultry farming, because they significantly slow down the growth rate of the industry and lead to losses. For the productive development of the industry and the avoidance of danger to the health of consumers due to the uncontrolled use of these drugs, it is worth using alternative methods of protecting poultry and improving the quality of the obtained products, in particular drugs obtained by nanotechnological means. Nowadays, nanoparticles of various minerals are used in poultry farming, the mineral antagonism of which is reduced in the intestines, compared to preparations of the usual size, which contributes to the modulation of absorption mechanisms, optimization of the immune response, and increased efficiency of digestion. Oxidative stress is a harmful factor for cellular integrity due to the constant release of reactive forms of oxygen. Se is widely used as a supplement to reduce oxidative stress. The element is found in organic and inorganic compounds, replaces Sulfur in protein molecules and is an important part of selenoproteins. Se is known for its antioxidant activity, plays a major role in optimizing redox potential, reproductive processes, hormone metabolism, muscle development, and anticarcinogenesis. Nano-Se results in higher Se retention activity due to smaller size and greater bioavailability. Biogenic selenium nanoparticles (SeNPs), synthesized with the participation of bacteria, have unique physicochemical and biological properties compared to inorganic and organic compounds, and nanoselenium-enriched probiotic bacteria can be effectively used as an alternative to other forms of selenium as food and feed additives. The work compared the composition of fatty acids of lipids extracted from erythrocytes of quail blood, which were injected with sodium selenite and pro-oxidant nano-Se. With the introduction of nanoselenium, a decrease in the level of NFAs was noted, as well as a significant increase in the level of the main PUFAs. The lack of compensatory accumulation of docosapolyene fatty acids in the cell membranes of erythrocytes of birds of the 2nd group can be considered as a factor of the beneficial effect of the administered drug, as well as as a justification for the need to prescribe complex drugs to birds capable of modulating the fatty acid composition of cell membranes. The effectiveness of using a complex nanopreparation consists in normalizing the level of fatty acids and restoring their metabolism at the stage of eicosanoid formation. Key words: fatty acids, quails, peroxide oxidation, selenium, sodium selenite, nanoselenium, nanoparticles, lipids.
