Проведена оценка совместного использования гамма-окталактона и хлортетрациклина в рационе бройлеров на рост, развитие, состояние организма и эффективность использования корма. Гамма-окталактон выделен из экстракта Eucalyptus viminalis. Схема эксперимента включала контрольную группу — основной рацион (ОР); I группа (положительный контроль) — ОР + хлортетрациклин (20%), 0,63 г на 1 кг массы тела в течение 20 дней; II группа — ОР + гамма-окталактон в дозировке 0,1 мл/кг ж.м./сут.; III группа — ОР + гамма-окталактон + хлортетрациклин (20%).</p></sec><sec><title>Результаты</title><p>Результаты. В ходе исследований было установлено преимущество по живой массе опытных бройлеров над контролем. Наибольшей живой массой отличались бройлеры, получавшие с основным рационом гамма-октолактон + хлортетрациклин (на 16,5% больше, чем в контроле). Аналогичная ситуация наблюдалась и по приростам живой массы. Бройлеры опытных групп поедали корма больше на 3,23–8,47% на фоне более низкого расхода корма на 1 кг живой массы (на 6,38–10,6%) по сравнению с контролем. Бройлеры из III группы имели большее содержание эритроцитов (на 12,6–30,7%) и массу селезенки. Микробный профиль бройлеров III группы (сочетание гамма-окталактона и хлортетрациклина) был представлен микроорганизмами, относящимся к 4 филумам. Доминатом являлся филум Firmicutes (81,3%). Сравнение с контролем показало, что сочетание веществ уменьшило численность бактерий данного филума на 4,46% на фоне увеличения количества представителей филума Bacteroidetes на 9,32%. Наблюдалось увеличение представителей родов Alistipes, Lactobacillus и неклассифицированных родов семейства Clostridiales, при этом уменьшалось количество представителей неклассифицированных родов семейства Ruminococcaceae. Таким образом, при совместном использовании гамма-окталактона с хлортетрациклином усиливается ростостимулирующий эффект на фоне высокой поедаемости корма, снижения расхода корма на 1 кг живой массы, увеличения эритропоэза и лейкоцитов в крови. </p></sec></abstract><trans-abstract xml:lang="en"><p>Relevance, materials and methods. The experimental scheme included the control group — the main diet (MD); group I (positive control) — MD + chlortetracycline (20%) 0.63 g per 1 kg of body weight for 20 days; group II — MD + gamma-octalactone at a dosage of 0.1 ml/kg of b.w./day; III group — MD + gammaoctalactone + chlortetracycline (20%).</p><p>Results. In the course of research, the advantage of the live weight of experimental broilers over the control was established. The broilers that received gamma-octolactone + chlortetracycline with the main dietwere distinguished by the greatest live weight (16.5% more than in the control) . A similar situation was observed in terms of live weight gains. Broilers of the experimental groups ate more feed (by 3.23–8.47%), against the background of low feed consumption per 1 kg of live weight (by 6.38–10.6%) compared to the control. Broilers from group III had a higher content of erythrocytes (by 12.6–30.7%) and the weight of the spleen. The microbial profile of group III broilers (a combination of gamma-octalactone and chlortetracycline) was represented by microorganisms belonging to 4 phylum. The dominant phylum was Firmicutes (81.3%). Comparison with the control showed that the combination of substances reduced the number of bacteria of this phylum by 4.46%, against the background of an increase in the number of representatives of the Bacteroidetes phylum by 9.32% relative to the control. There was an increase in representatives of the genera Alistipes, Lactobacillus and unclassified genera of the family Clostridiales, while the number of representatives of unclassified genera of the family Ruminococcaceae decreased. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>лактоны</kwd><kwd>антибиотики</kwd><kwd>кровь</kwd><kwd>живая масса</kwd><kwd>цыплята-бройлеры</kwd><kwd>кормление</kwd><kwd>экстракт листьев Eucalyptus viminalis</kwd><kwd>гамма-окталактон</kwd><kwd>химические элементы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lactones</kwd><kwd>antibiotics</kwd><kwd>blood</kwd><kwd>live weight</kwd><kwd>broiler chickens</kwd><kwd>feeding</kwd><kwd>extract of Eucalyptus viminalis</kwd><kwd>gamma-octalactone</kwd><kwd>chemical elements</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследования выполнены по проекту РНФ №16-16-10048 и теме НИР № 0526-2019-0002.</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The research was carried out according to the RSF project No. 16-16- 10048 and research project No. 0526-2019-0002.</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">Ferri M, Ranucci E, Romagnoli P, Giaccone V.
