Его изучение необходимо для детального понимания процессов, происходящих между микроорганизмами, населяющими определенный орган, и их взаимосвязи с клетками макроорганизма. Оценка состояния микробного сообщества животных и его функции может оказать неоценимую помощь в поиске новых стратегий повышения эффективности кормления и сохранения здоровья крупного рогатого скота. Целью исследования было сравнение таксономической структуры микробиома кишечника крупного рогатого скота абердин-ангусской породы, импортированного в Казахстан, и коров местных пород с помощью технологии секвенирования нового поколения. Был определен полный микробный состав содержимого кишечника животных при исследовании образцов экскрементов без предварительной стадии микробиологического культивирования на питательных средах. Результаты 16S метагеномного анализа показали, что доминирующими бактериальными таксонами в микробиоме кишечника животных обеих групп на уровне типа были Firmicutes и Proteobacteria примерно в одинаковом количестве. На уровне бактериальных семейств численность представителей Clostridiaceae была немного больше у коров абердин-ангусской породы (19,7%), чем у скота местной породы (15,4%). Представители семейств Bacteroidaceae, Peptococcaceae, Ruminococcaceae и Coriobacteriaceae преобладали в микробном сообществе кишечника местного скота. Данные микроорганизмы участвуют в синтезе витаминов, стимулируют иммунную функцию организма, нормализуют пищеварение, увеличивают усвояемость питательных веществ и, как следствие, повышают привесы у животных. Бактерии семейства Prevotellaceae были выявлены в небольшом количестве (0,5%) только у коров местной породы, которые имели высокие привесы. На уровне рода значительное разнообразие наблюдали в микробиоме местного скота: всего 65 таксонов против 40 у абердин-ангусов. Установлено, что в кишечном микробиоме крупного рогатого скота местных пород содержится меньшее количество метаногенов и большее количество ацетогенов. </p></abstract><trans-abstract xml:lang="en"><p>Animal microbiome plays a significant role in all the vital body processes. Studying the microbiome is essential for gaining a detailed insight into the interactions among microorganisms inhabiting a certain organ and their relationship with macroorganism cells. Evaluating the state of animal microbial community and its function can provide an invaluable assistance in seeking new strategies to improve feed efficiency and maintain cattle health. The aim of the study was to compare the taxonomic structure of the intestinal microbiome of Aberdeen Angus cattle imported to Kazakhstan with that of local breed cows using next generation sequencing technology. The tests of fecal samples allowed for determination of the complete microbial composition of animal intestinal contents, while leaving out the preliminary stage of microbiological cultivation using nutrient media. The results of 16S metagenomic analysis showed that Firmicutes and Proteobacteria were predominant bacterial taxons at the phylum level in the intestinal microbiome in both groups of animals, with their numbers being roughly the same. At the bacterial familylevel, the number of Clostridiaceae was a little higher in Aberdeen Angus cows (19.7%) than in the local breed cattle (15.4%). The representatives of the families Bacteroidaceae, Peptococcaceae, Ruminococcaceae and Coriobacteriaceae prevailed in the gut microbial community of local cattle. These microorganisms are involved in the synthesis of vitamins, they stimulate the immune function of the body, normalize digestion, improve nutrient utilization and thus contribute to body weight gain in animals. Small numbers (0.5%) of bacteria of the family Prevotellaceae were detected only in the local breed cows demonstrating high body weight gain. The microbiome of the local cattle was characterized by a considerable diversity at the genus level: the total number of taxons amounted to 65, whereas in Aberdeen Angus cattle it was 40. It was found that the intestinal microbiome of local breed cattle includes less methanogens and more acetogens. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>микробиом</kwd><kwd>крупный рогатый скот</kwd><kwd>абердин-ангусская порода</kwd><kwd>секвенирование нового поколения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>microbiome</kwd><kwd>cattle</kwd><kwd>Aberdeen Angus</kwd><kwd>next generation sequencing</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа профинансирована и выполнена в рамках грантового проекта Комитета науки Министерства образования и науки Республики Казахстан ИРН AP09259133 «Исследование микробиома желудочно-кишечного тракта крупного рогатого скота с целью уменьшения выбросов парниковых газов».</funding-statement><funding-statement xml:lang="en">The study was funded and carried out within the framework of the grant project of the Science Committee of the Ministry of Education and Science of the Republic of Kazakhstan IRN AR09259133 “Cattle gastrointestinal microbiome studies aimed to reduce greenhouse gas emissions”.</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">Carberry C.
