В последние годы на рынке появилось большое количество новых растительных препаратов, в числе которых гамма-окталактон. Это соединение естественного природного происхождения, выделенное из экстракта листьев эвкалипта (Eucalyptus viminalis). Данное соединение обладает широким спектром терапевтических свойств, что связано с его противовоспалительным, антисептическим действием; способствует стимулированию аппетита, повышению секреции пищеварительных ферментов и росту производственных показателей у животных.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В работе изучены особенности накопления химических элементов в тканях тела цыплят-бройлеров при включении в состав рациона соединения гамма-окталактон. Исследования были проведены на цыплятах-бройлерах кросса «Арбор-Айкрес» в возрасте 7–42 дней. Согласно схеме эксперимента, в рацион цыплят 1-й, 2-й и 3-й опытных групп дополнительно вводили гамма-окталактон в дозах 0,05; 0,1 и 0,2 мл/кг ж.м./сут. Элементный состав биосубстратов был изучен с использованием атомно-эмиссионной и масс-спектрометрии.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что добавление гамма-окталактона способствовало перераспределению химических элементов в тканях тела подопытной птицы. В частности, бройлеры опытной группы, получавшие гамма-окталактон в дозе 0,05 мл/кг ж.м./сут. имели более высокие значения концентраций B, Co, Ni, Se, V, Zn в грудных мышцах. Анализ концентраций основных эссенциальных элементов в бедренных мышцах цыплят-бройлеров показал, что скармливание гамма-окталактона в дозировке 0,05 мл/кг ж.м./сут. сопровождалось достоверным увеличением содержания Са, Na, Fe, Si и Zn и снижением уровней Cr, Cu и Ni относительно особей контрольной группы. Также было отмечено достоверное увеличение концентраций Cu, Fe, Se, Zn, Mg, P в печени цыплят опытной группы, получавших в составе рациона гамма-окталактон в дозировке 0,1 мл/кг ж.м./сут., на фоне снижения концентраций Si и Na. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. In recent years, a large number of new herbal preparations have appeared on the market, including gamma-octalactone. It is a naturally occurring compound isolated from Eucalyptus viminalis leaf extract. This compound has a wide range of therapeutic properties, which is associated with its antiinflammatory, antiseptic effect, stimulates appetite, increases the secretion of digestive enzymes and increases performance in animals.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The paper studied the features of the accumulation of chemical elements in the body tissues of broiler chickens when the compound gamma-octalactone was included in the diet. The studies were carried out on broiler chickens of the Arbor Acres cross at the age of 7–42 days. According to the scheme of the experiment, inthe diet of chickens of the 1st, 2nd and 3rd experimental groups was added gamma-octalactone at a dosages of 0.05, 0.1 and 0.2 ml/kg of b.w./day. The elemental composition of biosubstrates was studied using atomic emission and mass spectrometry.</p></sec><sec><title>Results</title><p>Results. It was found that the addition of gamma-octalactone contributed to the redistribution of chemical elements in the body tissues of the experimental poultry. In particular, the broilers of the experimental group that received gamma-octalactone at a dosage of 0.05 ml/kg of b.w./day had higher concentrations of B, Co, Ni, Se, V, Zn in the pectoral muscles. An analysis of the concentrations of the main essential elements in the thigh muscles of broiler chickens showed that feeding gamma-octalactone at a dosage of 0.05 ml/kg of b.w./day was accompanied by a significant increase in the content of Ca, Na, Fe, Si and Zn and a decrease in the levels of Cr, Cu and Ni relative to poultry of the control group. There was also a significant increase in the concentrations of Cu, Fe, Se, Zn, Mg, P in the liver of chickens of the experimental group, who received gamma-octalactone in the diet at a dosage of 0.1 ml/kg of l.w./day, against the background of a decrease in the concentrations of Si and Na. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>цыплята-бройлеры</kwd><kwd>кормление</kwd><kwd>экстракт листьев Eucalyptus viminalis</kwd><kwd>гамма-окталактон</kwd><kwd>химические элементы</kwd><kwd>печень</kwd><kwd>грудные мышцы</kwd><kwd>бедренные мышцы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>broiler chickens</kwd><kwd>feeding</kwd><kwd>extract Eucalyptus viminalis</kwd><kwd>gamma-octalactone</kwd><kwd>chemical elements</kwd><kwd>liver</kwd><kwd>pectoral muscles</kwd><kwd>femoral muscles</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование выполнено в рамках проекта № 0761-2019-0005 и гранта Российского научного фонда (проект №16-16-10048 П).</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The study was carried out within the framework of project No. 0761- 2019-0005 and grant from the Russian Science Foundation (project No. 16-16-10048 P).</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">Kvan O., Duskaev G., Rakhmatullin S., Kosyan D.
