Protective Action of Environments for Dilution Sperms of the Bulls Made With Application Alternative Components (Published)

Reproduction of animals in dairy cattle breeding is based on the wide application of artificial insemination of cattle and son cows the deep-frozen sperm. At deep freezing of sperm, an obligatory component of the cryoprotective environment is the native yolk of egg because of abundance in it of phospholipids and lipopoprotens which, interacting with plasma membranes sperm, strengthen their durability and stability. Being adsorbed by lipophilic and hydrophilic sites of plasma membranes, lipoid complexes almost thicken a cellular membrane that increases stability three times sperm to damaging temperature, osmotic, physical and chemical and to mechanical factors.
