Аbstraсt: Freezing of boar sperm diluted with the developed medium allows to obtain a concentration of hydrogen ions of 6,7-6,9 and osmotic pressure of 310-315 mOsm, minimize the decrease in motor activity of ejaculates after defrosting to 4.5 points, keep intact up to 51.1% of acrosome membranes and reduce the number of pathological forms of sperm to 17-20%. The inclusion of recombinant human lactoferrin in the diluent contributes to higher results of sperm sanitation: a minimum value of the coli-titer (0.001) and a negative value of the total microbial number of microorganisms were established. Insemination of pigs with ejaculates diluted with the developed cryopreservation medium ensures the fertilization of sows at the level of 53.3% and the level of multiple fertility of 10.1 heads/farrowing.
