Одним из путей её решения является разработка и использование в рационе животных биологически активных кормовых добавок. К таким добавкам относят кормовые продукты, содержащие живые (активные) дрожжи, которые используются в кормлении сельскохозяйственных животных в качестве пробиотиков с целью оптимизации процессов пищеварения, повышения продуктивности и сохранности поголовья. В статье представлены результаты изучения влияния кормовой добавки MDK производства ОАО «Дрожжевой комбинат», содержащей живые дрожжи Saccharomyces boulardii, на продуктивность молодняка крупного рогатого скота. За период проведения научно-хозяйственного опыта отмечено положительное влияние кормовой добавки с дрожжами на морфо-биохимические показатели крови животных. Также установлено, что использование в рационах молодняка крупного рогатого скота кормовой добавки в количестве 10 г на голову в сутки способствует увеличению среднесуточных приростов на 17,0 %, что позволило снизить себестоимость получаемой продукции на 10,4 % и получить дополнительную прибыль в размере 39,9 рублей в расчёте на 1 голову.</p></abstract><trans-abstract xml:lang="en"><p>Increasing the production of animal products is an important task facing the food and agricultural industry in Belarus. One of the ways for its solution is the development and use of biologically active feed additives in the animal diet. Such additives include feed products containing living (active) yeast used in the feeding of farm animals as probiotic to optimize digestive processes, improve the livestock productivity and livability. The article presents the results of studying the effect of the MDK feed additive produced by JSC “Yeast Plant”, containing Saccharomyces boulardii living yeast, on the productivity of young cattle. During the period of scientific and economic experiment, a positive effect of the yeast-based feed additive on morpho-biochemical parameters of animal blood was established. It was also found that the use of feed additive in the diets of young cattle in the amount of 10 g per animal per day contributed to an increase in average daily gains by 17.0%, which made it possible to reduce the cost of production by 10.4% and obtain an additional profit of 39.9 rubles per animal.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>молодняк крупного рогатого скота</kwd><kwd>кормовая добавка</kwd><kwd>продуктивность</kwd><kwd>кровь</kwd><kwd>экономические показатели</kwd></kwd-group><kwd-group xml:lang="en"><kwd>young cattle</kwd><kwd>feed additive</kwd><kwd>productivity</kwd><kwd>blood</kwd><kwd>economic indicators</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">Дрожжи как основа биологически активных кормовых добавок про- и пребиотического действия / А.
