PRESERVATION OF BULL SEMEN USING POLYSACCHARIDES OF BASIDIOMYCETES HERICIUM ERINACEUS BP 16

Abstract

For the first time, a study was conducted to determine the effectiveness of the use of Hericium erinaceus BP 16 polysaccharides mixed with AndroMed® to preserve the motility of bull spermatozoa after freezing and storage at -5 °C. H. erinaceus polysaccharides have been shown to increase the osmolarity of AndroMed® solution, which lowers its freezing point. It has been established that the motility of progressive spermatozoa after 7 days of storage at - 5°C is preserved to the greatest extent in the presence of H. erinaceus polysaccharides in the biological medium. At the same time, in the group with polysaccharides, there was a decrease in such indicators of mobility as the speed along the average trajectory, wobble, and beat frequency. The data obtained indicate the promise of using H. erinaceus polysaccharides as part of a cryoprotective solution to preserve the functional usefulness of gametes during their freezing.
