Известно, что генотипические особенности животных отражаются на активности функционирования регуляторных систем, что сопровождается изменениями в интенсивности и направленности пищеварительных и обменных процессов. Переваримость и использование питательных веществ, а также потребность в них у животных разного происхождения неодинаковы. Изучение видового состава и ферментативных свойств микроорганизмов у гибридных животных представляет большой интерес. Научные исследования в этой области могут расширить видовое многообразие целлюлозолитических микроорганизмов за счет использования диких форм овец, у которых процесс расщепления и переваривания сырой клетчатки происходит более интенсивно.</p></sec><sec><title>Методы</title><p>Методы. Видовой состав микрофлоры и основные группы микроорганизмов (общее микробное число (ОМЧ), молочнокислые, энтерококки, дрожжеподобные грибы и целлюлозолитические микроорганизмы) определяли в лаборатории микробиологии ФГБНУ ФИЦ ВИЖ им. Л.К. Эрнста в 2021–2023 гг. методом высева десятикратных разведений на накопительные и дифференциально-диагностические среды с последующим подсчетом их количества (КОЕ/мл) по группам микроорганизмов.</p></sec><sec><title>Результаты</title><p>Результаты. По результатам исследования видового состава рубцового содержимого гибридных овец разной кровности наибольшее количество по основным группам микроорганизмов отмечено у гибридов овец — 1/4 архар × 3/4 романовская. Наибольшее количество целлюлозолитических микроорганизмов, обладающих высокой ферментативной активностью, было выделено у четырехпородных гибридов: 1/32 архар × 7/32 романовская × 8/32 муфлон × 16/32 катадин.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. It is known that genotypic features affect the activity of the functioning of regulatory systems, which is accompanied by changes in the intensity and direction of digestive and metabolic processes. The digestibility and use of nutrients, as well as the need for them in animals of different origins are not the same. Therefore, the study of the species composition and enzymatic properties of microorganisms in hybrid animals is of great interest. Scientific research in this area can expand the species diversity of cellulolytic microorganisms through the use of wild forms of sheep, in which the process of splitting and digesting raw fiber occurs more intensively.</p></sec><sec><title>Methods</title><p>Methods. The species composition of the microflora and the main groups of microorganisms (total microbial number (OMH), lactic acid, enterococci, yeast-like fungi and cellulolytic microorganisms) were determined in the microbiology laboratory of the L.K. Ernst FITZ VIZH in 2021–2023 by seeding tenfold dilutions into accumulative and differential diagnostic media, followed by counting their number (CFU/ml) by groups of microorganisms.</p></sec><sec><title>Results</title><p>Results. According to the results of the study of the species composition of the scar content of hybrid sheep of different bloodlines, the largest number of microorganisms in the main groups was observed in hybrids — sheep 1/4 Argali × 3/4 Romanovskaya. The largest number of cellulolytic microorganisms with high enzymatic activity was isolated from four-breed hybrids: 1/32 Argali × 7/32 Romanovskaya × 8/32 Mouflon × 16/32 Katadin.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рубец</kwd><kwd>гибридные овцы</kwd><kwd>микроорганизмы</kwd><kwd>целлюлозолитические микроорганизмы</kwd><kwd>жвачные животные</kwd></kwd-group><kwd-group xml:lang="en"><kwd>scar</kwd><kwd>hybrid sheep</kwd><kwd>microorganisms</kwd><kwd>cellulolytic microorganisms</kwd><kwd>ruminants</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Материалы подготовлены в рамках государственного задания НИР по теме FGGN-2021-0002 «Совершенствование систем кормления животных, включая элементы кормопроизводства, на основе новых знаний, полученных при изучении нормирования потребностей в энергии и питательных веществах и разработке новых приемов и способов питания и регулирования физиолого-биохимических, метаболических и микробиологических процессов в организме животных для повышения эффективности производства и улучшения качества животноводческой продукции».</funding-statement><funding-statement xml:lang="en">The materials were prepared as part of the state research assignment on the topic FGGN-2021-0002 «Improvement of animal feeding systems, including elements of feed production, based on new knowledge gained in the study of rationing energy and nutrient requirements and the development of new methods and methods of nutrition and regulation of physiological, biochemical, metabolic and microbiological processes in the body of animals to increase production efficiency and improve the quality of livestock products.»</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Пивняк И.Г., Тараканов Б.В.
