Возможно это за счет применения новых кормовых добавок, включающих биологически активные вещества. В результате исследований установлено, что все цыплята-бройлеры показали высокие результаты при их выращивании. Наибольшей живой массы достигли цыплята из II опытной группы, которые получали препарат «Арес» в количестве 0,6 г/кг комбикорма. Более низкие показатели оказались у цыплят из I и III опытных групп, однако они по живой массе в возрасте 36 дней превосходили нормативные показатели по кроссу и результаты, полученные в контрольной группе. Прослеживается повышение среднесуточных приростов в первой и третьей группах в течение всего периода выращивания и видно некоторое их снижение во второй группе в период с 24-го до 31-го дня с резким повышением в последний период с 31-го до 36-го дня.</p></abstract><trans-abstract xml:lang="en"><p>   The main costs of livestock production, including poultry farming, are related with the feed. Therefore it is very relevant to increase digestibility of feed, apply compound feeds from cheap raw materials produced domestically without reducing of nutritional value, and fully provide the poultry with substances necessary for their normal life. It is possible to achieve with the application of new feed additives, including biologically active substances. As a result of the research it was found that all broiler chickens showed high parameters of body condition during the boilers growing. The chickens from the II experimental group, which received the additive “Ares” in amount of 0.6 g/kg of feed, showed the highest live weight gain. Lower values were observed among the chickens of I and III experimental groups. However, in terms of live weight gain at the age of 36 days, these chickens exceeded the normal value parameters of the cross and the results obtained in the control group. The increase in the average daily weight gains in the first and third groups was observed throughout the entire period of fattening, and a slight decrease was observed in the second group in the period from 24th to 31th day with a sharp surge of weight gain in the last period from 31th to 36th day.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>птицеводство</kwd><kwd>цыплята</kwd><kwd>комбикорм</kwd><kwd>живая масса</kwd><kwd>пищевая ценность</kwd><kwd>«Арес»</kwd></kwd-group><kwd-group xml:lang="en"><kwd>poultry farming</kwd><kwd>chickens</kwd><kwd>feed</kwd><kwd>live weight</kwd><kwd>nutritional value</kwd><kwd>“Ares”</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">Vdovina N.
