Влияние кормов и пищевых добавок на его микробиом кишечника имеет как прикладную, так и фундаментальную значимость и демонстрирует стимулирование роста различных групп бактерий. Целью нашей работы является изучение влияния отечественного полнорационного корма Дилли на микробное сообщество кишечника собак питомника г. Иркутска. Состав микробиома определяли у 12 животных разного возраста с помощью секвенирования ампликонов V3-V4 региона 16S рРНК на Illumina MiSeq. Коэффициенты разнообразия применяли для оценки богатства и представленности бактериальных ОТЕ, а непараметрический критерий Манна-Уитни (парный тест, p≤0,05) использовали для оценки достоверности разницы процентного содержания ОТЕ у различных физиологических групп. Всего получено 147150 последовательностей фрагмента гена 16S рРНК. Доминирующими являлись бактерии филумов Firmicutes, Actinobacteriota, Bacteroidota, Proteobacteria. У исследуемых животных почти отсутствовали бактерии Fusobacteriota – маркеры диеты с преобладанием сырого мяса (хищничества). Филум Firmicutes включал бактерий пяти семейств. Самым многочисленным семейством среди фирмикут были бактерии Lactobacillaceae. Среди бактерий Actinobacteriota наблюдали представителей семи семейств, из которых доминировали Bifidobacteriaceae. Протеобактерии порядка Enterobacterales и Burkholderiales составляли малую долю от всего сообщества, и зависели от возраста животного. Результаты исследований в перспективе могут быть использованы для расширения знаний о процессе пищеварения у всеядного животного рода волков. У этих животных достаточно пластичный микробиом, который имеет несколько вариантов нормального состава. В микробных сообществах кишечника собак, потребляющих в пищу корма, содержащие грубые пищевые волокна, преобладали молочнокислые бактерии. В свою очередь, молочнокислые бактерии редуцировали численность Fusobacteriota. </p></abstract><trans-abstract xml:lang="en"><p>Metabarcoding research of the domestic animal intestines is relevant for veterinary medicine. The effect of feeding and food additives on its gut microbiome is of both applied and fundamental significance and demonstrates the stimulation of the various groups of bacteria development. The objective of our work is to study the effect of the domestic complete pet feed Dilly on the microbial community of the dogs’ intestines in breeding kennel of Irkutsk. The microbiome composition was determined in 12 animals of different ages having used Illumina MiSeq amplicon sequencing of the V3-V4 region of 16S rRNA. Rates diversity had been adapted to evaluate the affluence and prominence of Bacterial operational and taxonomic units and nonparametric Mann-Whitney criteria (correlative test, p≤0,05) used to evaluate the certainty value of the difference of operational and taxonomic unit percentage in different physiological groups. All in all, 147150 the 16S rRNA gene fragment sequences were obtained. The dominant bacteria turned out to be the phyla Firmicutes, Actinobacteriota, Bacteroidota, and Proteobacteria. The animals that had been under research had almost no Fusobacteriota bacteria - markers of a diet with a predominance of raw meat (predation). The Firmicutes phylum included bacteria from five families. The most numerous families among the Firmicutes were the Lactobacillaceae bacteria. Representatives of seven families were observed among Actinobacteriota bacteria, of which Bifidobacteriaceae predominated. Proteobacteria of the Enterobacterales order and Burkholderiales made up a small proportion of the entire community and depended on the animal age. The research result could be used in perspective to enlarge knowledge about the digestive process in an omnivorous animal of the wolf pack. These animals have a more or less flexible microbiome, which has several variants of normal composition. There predominated lactic acid bacteria in the microbial communities of the dogs’ intestines, which consumed feed that contained coarse dietary fibers. In its turn, lactic acid bacteria reduced the number of Fusobacteriota.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>собака</kwd><kwd>углеводная диета</kwd><kwd>микробиом кишечника</kwd><kwd>бактерии</kwd><kwd>метабаркодинг 16S рРНК</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dog</kwd><kwd>hydrocarbon diet</kwd><kwd>intestine microbiome</kwd><kwd>bacteria</kwd><kwd>16S rRNA metabarcoding</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">Pereira A.M. et al.
