Над повышением уровня результативности данной технологии работают уже одно не десятилетие, однако до сих пор ряд проблем технологического и биологического характера остаётся нерешённым. Целью наших исследований явилось изучение влияния различных паратипических факторов на приживляемость эмбрионов. Работа проводилась в течение 2019-2020 годах в ОАО «Гастелловское» Минского района. В качестве доноров использовались лактирующие полновозрастные коровы и тёлки голштинской породы в возрасте 11-12 месяцев. По результатам исследований установлено 249 стельных реципиентов из 476 эмбриопересадок, что составило 52,3 %. Пересадка эмбрионов в зимний период снижала уровень стельности на 11,0 п.п., 4,9 и 9,2 п.п. по сравнению с весной, летом и осенью соответственно. Наиболее эффективным оказался сентябрь месяц, уровень стельности в котором составил 73,9 %. </p></abstract><trans-abstract xml:lang="en"><p>In modern dairy and beef cattle breeding, embryo transfer allows for the accelerated breeding of animals with high productivity rates, which provides vast opportunities in breeding and reproduction of cattle to improve the efficiency of breeding work. This technology has been worked on for more than a decade, but still a number of technological and biological problems remain unsolved. The aim of our research was to study the effect of various paratypical factors on embryo survival rate. The work was carried out during 2019-2020 in JSC “Gastellovskoe”, Minsk district. Holstein lactating mature cows and heifers aged 11-12 months were used as donors. According to the results of the research, 249 pregnant recipients were identified out of 476 embryo transfers, which amounted to 52.3%. Embryo transfer in winter decreased the pregnancy rate by 11.0 p.p., 4.9 p.p. and 9.2 p.p. compared to spring, summer and fall, respectively. September was the most effective month, with a pregnancy rate of 73.9%. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>донор</kwd><kwd>реципиент</kwd><kwd>морула</kwd><kwd>бластоциста</kwd><kwd>качество</kwd><kwd>приживляемость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>donor</kwd><kwd>recipient</kwd><kwd>morula</kwd><kwd>blastocyst</kwd><kwd>quality</kwd><kwd>survival rate</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">Development of bovine embryos derived from reproductive techniques / M.
