Известно, что импортный препарат Плюссет (соотношение ФСГ:ЛГ - 1:1) надежно индуцирует овуляцию, тогда как отечественный ФСГ-Супер (1000:1) демонстрирует более низкую результативность, что, по-видимому, связано с дефицитом ЛГ-компонента. Цель настоящего исследования — количественно и качественно оценить, компенсирует ли дополнительное введение гонадорелина (как источника ЛГ/ФСГ-пика) недостаток ЛГ в стандартном протоколе суперовуляции с ФСГ-Супер у коров голштинской породы.В опыт включено 38 коров 2–3-й лактаций (TPI ≥ 2590), распределённых на контроль (n = 17) и опыт (n = 21). Обе группы прошли 18-дневную схему с CIDR, четырьмя инъекциями ФСГ-Супер (∑ 1000 МЕ) и простагландином; в опытной группе дополнительно вводили 100 мг гонадорелина на 9-й день. Овариальный ответ оценивали по числу жёлтых тел, эмбриопродуктивность — по общему количеству, среднему выходу на корову и пригодности эмбрионов.У подопытных животных количество желтых тел колебалось от 5 до 12 (8,3±3,1), у контрольных — 3–8 (5,8±1,8). Получено 134 эмбриона против 81 (рост 65,4 %), средний выход — 6,4 ± 0,5 и 4,8 ± 0,4 соответственно (p = 0,012). Доля пригодных к трансплантации эмбрионов не различалась статистически.Таким образом, включение гонадорелина в схему ФСГ достоверно повышает количественные показатели суперовуляции без ухудшения качества эмбрионов, что подтверждает целесообразность внедрения модифицированного протокола.</p></abstract><trans-abstract xml:lang="en"><p>In highly productive Holstein herds, variability in ovarian response remains a key limiting factor in the effectiveness of embryo transfer programs. It is known that the imported preparation Pluset (FSH:LH ratio of 1:1) reliably induces ovulation, whereas the domestic FSH-Super (FSH:LH ratio of 1000:1) demonstrates lower efficacy, presumably due to LH deficiency. The aim of this study was to quantitatively and qualitatively assess whether the additional administration of gonadorelin (as a source of the LH/FSH surge) can compensate for the low LH content in a standard superovulation protocol using FSH-Super in Holstein cows.The study included 38 Holstein cows in their 2nd–3rd lactation (TPI ≥ 2590), divided into a control group (n = 17) and an experimental group (n = 21). Both groups received an 18-day protocol involving a CIDR device, four injections of FSH-Super (total dose: 1000 IU), and prostaglandin. In the experimental group, 100 µg of gonadorelin was additionally administered on day 9. Ovarian response was evaluated by the number of corpora lutea; embryo productivity was assessed based on total embryo yield, mean embryos per cow, and embryo quality.In the experimental group, the number of corpora lutea ranged from 5 to 12 (most commonly 8–10), while in the control group the range was 3 to 8 (commonly 4–6). A total of 134 embryos were obtained in the experimental  group versus 81 in the control (a 65.4% increase); the average yield per cow was 6.4 ± 0.5 and 4.8 ± 0.4, respectively (p = 0.012). The proportion of embryos suitable for transfer did not differ significantly between groups.Thus, the inclusion of gonadorelin in the FSH-Super protocol significantly increases quantitative indicators of superovulation without compromising embryo quality, supporting the feasibility of implementing the modified protocol in reproductive biotechnology for high-yielding dairy herds.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>голштинская порода</kwd><kwd>крупный рогатый скот</kwd><kwd>суперовуляция</kwd><kwd>ФСГ -Супер</kwd><kwd>эмбриопродуктивность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Holstein breed</kwd><kwd>cattle</kwd><kwd>superovulation</kwd><kwd>FSH-Super</kwd><kwd>embryo productivity</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">Ачилов В.В.
