Введение добавки в комбикорма способствует нормализации обмена веществ молодняка, увеличению концентрации в крови низкомолекулярных антиоксидантов и обеспечивает повышение среднесуточных приростов живой массы на 3,3 и 7,8 % и снижение себестоимости 1 кг прироста на 1,2 и 3,7 % в сравнении с контролем.</p></abstract><trans-abstract xml:lang="en"><p>The efficiency of prebiotic feed supplement of complex action containing lactulose in the diets of young cattle under 6 months of age was studied. The introduction of the feed supplement into feeds helps to normalize the metabolism of young animals, increase low molecular weight antioxidants concentration in blood and increases the average daily weight gain by 3.3 and 7.8 % and decrease the cost of 1 kg of weight gain by 1.2 and 3.7 % compared to control.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кормовая добавка</kwd><kwd>пребиотик</kwd><kwd>лактулоза</kwd><kwd>молодняк крупного рогатого скота</kwd><kwd>кровь</kwd><kwd>живая масса</kwd></kwd-group><kwd-group xml:lang="en"><kwd>premix</kwd><kwd>young cattle</kwd><kwd>tripoli</kwd><kwd>filler</kwd><kwd>wheat bran</kwd><kwd>minerals</kwd><kwd>average daily gain</kwd><kwd>economic efficiency</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">Беюп, Е.
