Поэтому уже сегодня многие производители племенной продукции получают свой молодняк исключительно через трансплантацию эмбрионов, полученных через суперовуляцию или посредством технологии in vitro. В связи с этим, изучена эффективность двухлетней работы по трансплантации эмбрионов в ОАО «Гастелловское» Минского района. По результатам двухлетней работы было произведено 1380 эмбрионов, из которых 79,5 % оказались пригодными для трансплантации. Выход жизнеспособных эмбрионов в весенний период был в целом выше, чем зимой, летом и осенью на 4,6 п. п., 3,8 и 9,8 п. п. соответственно. При среднем показателе выхода жизнеспособных зародышей на донора 4,2-4,3 в зависимости от быка данный показатель колебался от 1,0 до 6,8. Оплодотворяемость яйцеклеток находилась примерно на одном уровне и составляла 80,9-81,6 %.</p></abstract><trans-abstract xml:lang="en"><p>Embryo transfer plays a major role in genetic improvement and accelerated creation of breeding herds: it allows increasing the young breeding cattle production by one cow, reducing the generation interval and significantly accelerating the process of qualitative improvement of the cattle population, which is especially important when introducing genomic selection into selection and breeding work. So, even nowadays, many breeders obtain their young stock exclusively through the embryo transfer applying superovulation or in vitro technology. In this regard, the effectiveness of the two-year work on embryo transfer at JSC “Gastellovskoe” of the Minsk region was studied. According to the results of the two-year work, 1,380 embryos were produced, of which 79.5% were suitable for transplantation. The yield of viable embryos in the spring period was generally higher than in winter, summer and autumn by 4.6 p.p., 3.8 and 9.8 p.p., respectively. With an average yield of viable embryos per donor of 4.2-4.3, depending on the bull, this index ranged from 1.0 to 6.8. The oocyte fertilization rate was approximately at the same level and amounted to 80.9-81.6%.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>доноры</kwd><kwd>эмбрионы</kwd><kwd>яйцеклетка</kwd><kwd>морула</kwd><kwd>бластоциста</kwd><kwd>качество</kwd><kwd>стадия развития</kwd></kwd-group><kwd-group xml:lang="en"><kwd>donors</kwd><kwd>embryos</kwd><kwd>oocyte</kwd><kwd>morula</kwd><kwd>blastocyst</kwd><kwd>quality</kwd><kwd>maturity stage</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">Heape, W.
