It is proved that electromagnetic radiation of superhigh frequencies affects the fundamental vital processes of living organisms. However, the question of the effect of prolonged exposure to an ultra-low frequency alternating pulsed electromagnetic field (ZIEMP LF) on lipid metabolism in the poultry is now insufficiently illuminated. The purpose of the work is to study the effect of an alternating pulsed electromagnetic field of ultra-low frequency on lipid metabolism in the blood serum of research hens of the Tetra X cross. For this purpose, four
research and control groups of 120-day-old hens — 15 birds each. The bird was kept in a specially equipped room with an alternating pulsed electromagnetic field
of an ultra-low frequency. The serum lipids in the blood serum were determined by competitive enzyme-linked immunosorbent assay using standard methods. According to the results of studies, it was found that with prolonged exposure to ZIEMP LF, significant changes in lipid metabolism were detected, which was manifested by a change in the level of its main indicators in the blood serum of chickens. According to the results of 112-day exposure of ZIEMP LF for 30 minutes, a significant increase in the level of free triacylglycerols in blood serum
was detected, which predictably activates energy metabolism and, accordingly, improves the productivity of chickens. At the same time, an increase in cholesterol
levels in the blood serum of chickens was noted mainly due to HDL and, accordingly, a decrease in the atherogenicity index, which in particular indicates
the activation of the process of delivery of cholesterol molecules from cells to the liver and other tissues, the active removal of cholesterol from cells by esterification, and the prevention of cholesterol sedimentation on the walls of blood vessels. An increase in the exposure time of ZIEMP NPS to 174 days under the above-mentioned regimes, on the contrary, led to an increase in blood serum cholesterol levels mainly due to the so-called “harmful” lipoprotein fractions of LDL and VLDL and, accordingly, an increase in the atherogenic index, therefore, a negative effect on lipid metabolism research chickens.
