Согласно полученным данным, использование в составе комбикормов для высокопродуктивных коров добавки кормовой «Лактумин» в количестве 0,3, 0,6 и 0,9 % или 25, 50 и 75 г на голову в сутки способствует получению дополнительно в расчёте на одну корову 1,0, 1,2 и 0,9 кг молока 3,6%-ной жирности. Наиболее оптимальной дозировкой добавки кормовой «Лактумин» в составе концентратной части рациона высокопродуктивных коров является 0,6%, которая позволяет получить дополнительную прибыль от полученного молока за 96 дней в количестве 79,49 руб. при окупаемости 1 рубля затрат на добавку в размере 8,7 руб.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents the results of study of efficiency of the feed additive “Lactumin” used in the diets of lactating cows. According to the data obtained, feed additive “Lactumin” used in compound feeds for highly productive cows in the amount of 0.3, 0.6 and 0.9% or 25, 50 and 75 g per animal per day contributes to extra production of 1.0, 1.2 and 0.9 kg of 3.6% fat milk per cow. The perfect dosage of feed additive “Lactumin” in concentrate portion of diet for highly productive cows is 0.6%, which allows to get additional profit from milk obtained in 96 days in the amount of 79.49 rubles with recoupment of 1 ruble of expense for additive in the amount of 8.7 rubles.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>высокопродуктивные коровы</kwd><kwd>кормовая добавка «Лактумин»</kwd><kwd>молочная продуктивность</kwd><kwd>экономическая эффективность</kwd><kwd>highly productive cows</kwd><kwd>Lactumin feed additive</kwd><kwd>dairy performance</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">Киселёв, А.
