Установлено, что применение двухступенчатого режима оттаивания (последовательное нагревание пайетт на воздухе при температуре +20 °С в течение 10 секунд, а затем в водяной бане при +37 °С также 10 секунд) в отличие от одноступенчатого (оттаивание замороженных пайетт в водяной бане при температуре +37 °С в течение 10 секунд) позволяет увеличить число зародышей, сохранивших своё первоначальное отличное качество, на 19,3 п. п., 7,0 и 14,7 п. п., долю клеток отличного и хорошего качества - на 6,9 п. п., 6,8 и 11,4 п. п., выход пригодных к трансплантации эмбрионов - на 3,6 п. п., 6,5 и 19,3 п. п. при криоконсервации биоматериала коз в различных криопротекторах на основе глицерина, этиленгликоля и диметилсульфоксида соответственно.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of the study of the viability of depreserved goat embryos depending on different technological modes of thawing used in the technology of transplantation of small ruminants. It has been established that the use of a twostage thawing mode (successive heating of the straws in air at a temperature of +20°C for 10 seconds, and then in a water bath at +37 °C also for 10 seconds), in contrast to a single-stage thawing mode (thawing of frozen straws in a water bath at +37 °С for 10 seconds), allows to increase the number of embryos that have retained their original excellent quality by 19.3 p.p., 7.0 and 14.7 p.p., the proportion of cells ofexcellent and good quality - by 6.9 p.p., 6.8 and 11.4 p.p., the yield of embryos suitable for transplantation - by 3.6 p.p., 6.5 and 19.3 p.p. with cryopreservation of goat biomaterial in various cryoprotectants based on glycerol, ethylene glycol and dimethyl sulfoxide, respectively.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>коза</kwd><kwd>жизнеспособность</kwd><kwd>деконсервация</kwd><kwd>эмбрион</kwd><kwd>криофилактик</kwd></kwd-group><kwd-group xml:lang="en"><kwd>goat</kwd><kwd>viability</kwd><kwd>depreservation</kwd><kwd>embryo</kwd><kwd>cryoprotectant</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Эрнст, Л.
