Холин может действовать как донор метила для снижения уровня глутатиона в мозге, блокируя развитие ОС и препятствуя развитию воспалительных процессов, что является профилактикой нарушения дисбиотических состояний. Цель исследования — изучить влияние холина битартрата (ХБ) на микробиоту толстого кишечника свиней в период интенсивного роста. ХБ в составе основного рациона влиял на качественный и количественный состав микробиоты: увеличивалась доля нормофлоры, уменьшалась доля и представительство патогенных и условно-патогенных микроорганизмов. ХБ способствовал работе микроорганизмов, выделяющих метаболиты с высокой нейромедиаторной активностью, росту доли филумов продуцентов лактата — активатора кишечных макрофагов.</p></abstract><trans-abstract xml:lang="en"><p>Oxidative stress (OS) associated with inflammatory processes affects the intestinal microbiota. Choline can act as a methyl donor and reduce the level of glutathione in the brain, inhibiting the development of OS and inflammatory processes. In turn, this contributes to prevention of dysbiotic disorders. In this work, we study the effect of choline bitartrate (CB) on the microbiota of the large intestine of pigs during the period of intensive growth. CB introduced as part of the main diet was found to affect the qualitative and quantitative composition of the  microbiota. Thus, the proportion of normoflora increased, while the proportion and representation of pathogenic and  opportunistic microorganisms decreased. CB contributed to the work of microorganisms secreting metabolites with high neurotransmitter activity and led to an increase in the proportion of phylum producers of lactate, an activator of intestinal macrophages.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микробиота</kwd><kwd>окислительный стресс</kwd><kwd>холин битартрат</kwd><kwd>поросята</kwd><kwd>дисбактериоз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>microbiome</kwd><kwd>oxidative stress</kwd><kwd>choline bitartrate</kwd><kwd>piglets</kwd><kwd>dysbiosis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена в рамках государственного задания № 124020200032-4.</funding-statement><funding-statement xml:lang="en">the work was performed within the framework of the state assignment No. 124020200032-4.</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">Каркищенко В.Н., Фокин Ю.В., Люблинский С.Л., Помыткин И.А., Алимкина О.В., Табоякова Л.А., Капцов А.В., Борисова М.М., Каркищенко Н.Н.
