Abstract

The crucial task is to develop more advanced biotechnological methods and techniques that allow to increase the biological full-value of germ cells during their storage, so the purpose of our work was to study the efficiency of biophysical effects on
 the semen of billy goats during cryopreservation. Research has shown that it contributes to the preservation of biological full-value after thawing, and the developed treatment mode allows for the longest possible use of its genetic potential. Thus, the protocol of a single biophysical effect on male goats’ germ cells with a duration of exposure of 60 seconds contributes to long-term preservation of their biological full-value (up to 5 hours after depreservation), activation of spermatozoa vital activity processes, which allows to increase the pregnancy rate in female goats by 5-10 p.p.
