Исследования проводились в рамках двух государственных программ научных исследований: «Биотехнология» (подпрограмма «Развитие биологической науки, биологического образования и биологической промышленности на 2007-2011 год и на период до 2020 года»), «Наукоемкие технологии и техника на 2016-2020 годы» (подпрограммы 1 «Инновационные биотехнологии-2020»). Исследования проводили на базе отраслевой биотехнологической лаборатории по репродукции сельскохозяйственных животных УО «Гродненский государственный аграрный университет». В настоящей работе представлены результаты исследований по изучению влияния морфофункционального состояния яичников на выход эмбрионов предимплантационных стадий в культуре in vitro. По результатам исследований установлено, морфологические показатели яичников среднем составляли: длина -33,1±4,62 (lim – 21,3-43,1 мм), ширина – 19,2±1,32 (lim – 10,9-27,1 мм) при коэффициенте вариации 26,6%. Объем яичника в среднем составлял 6,8±0,62 (lim – 3,5-12,1 см3 ). Отмечается тенденция увеличения количества фолликулов и ооцитов у яичников объемом свыше 6,0 см3, при этом разница по количеству фолликулов диаметром 2-4 мм достоверна (P˂ 0,05). Более эффективным оказалось использование яичников с количеством фолликулов более 20 и их диаметром от 3 до 8 мм. Выход жизнеспособных эмбрионов при этом составлял 20,7-23,2% от числа оплодотворенных ооцитов и достоверно превышал аналогичный показатель по другим группам яичников при P˂ 0.01.</p><p>Полученные данные имеют практическую значимость для разработки технологии получения эмбрионов in vitro, использование которой будет способствовать ускорению селекционного процесса и повышению эффективности селекционно-племенной работы в скотоводстве в целом.</p></abstract><trans-abstract xml:lang="en"><p>It is impossible to solve the problem of modernization and dynamic development of dairy cattle breeding without qualitative improvement and renewal of the existing livestock. The research was carried out within the framework of two state research programs: "Biotechnology" (sub-program "Development of biological science, biological education and biological industry for 2007-2011 and for the period up to 2020"), "High-tech technologies and equipment for 2016-2020" (sub-program 1 "Innovative Biotechnologies-2020"). The research was conducted on the basis of the branch biotechnological laboratory for reproduction of farm animals of the State Educational Institution "Grodno State Agrarian University". This paper presents the results of studies on the influence of the morphofunctional state of the ovaries on the yield of preimplantation stage embryos in in vitro culture. According to the results of the studies, the morphological parameters of the ovaries were on average: length -33.1±4.62 (lim – 21.3-43.1 mm), width-19.2±1.32 (lim – 10.9-27.1 mm) with a coefficient of variation of 26.6%. The ovarian volume averaged 6.8±0.62 (lim – 3.5 -12.1 cm3). There is a tendency to increase the number of follicles and oocytes in ovaries with a volume of more than 6.0 cm3, while the difference in the number of follicles with a diameter of 2-4 mm is significant (P&lt;0.05). More effective was the use of ovaries with more than 20 follicles and a diameter of 3 to 8 mm. The yield of viable embryos in this case was 20.7-23.2% of the number of fertilized oocytes and significantly exceeded the same indicator for other ovarian groups at P&gt;&lt;0.01. The obtained data are of practical significance for the development of technology for obtaining embryos in vitro, the use of which will help to accelerate the selection process and increase the efficiency of breeding work in cattle breeding in general.&gt;˂ 0.05). More effective was the use of ovaries with more than 20 follicles and a diameter of 3 to 8 mm. The yield of viable embryos in this case was 20.7-23.2% of the number of fertilized oocytes and significantly exceeded the same indicator for other ovarian groups at P˂ 0.01.</p><p>The obtained data are of practical significance for the development of technology for obtaining embryos in vitro, the use of which will help to accelerate the selection process and increase the efficiency of breeding work in cattle breeding in general.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>крупный рогатый скот</kwd><kwd>донор</kwd><kwd>ооцит</kwd><kwd>in vitro</kwd><kwd>яичники</kwd><kwd>фолликул</kwd><kwd>экстракорпоральное оплодотворение (ЭКО)</kwd><kwd>воспроизводство животных</kwd><kwd>трансплантация эмбрионов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cattle</kwd><kwd>donor</kwd><kwd>oocyte</kwd><kwd>in vitro</kwd><kwd>follicle</kwd><kwd>in vitro fertilization (IVF)</kwd><kwd>animal reproduction</kwd><kwd>embryo transplantation</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">Голубец, Л.В.
