The studies were conducted on Holstein cows of red-and-white color. The cows were selected on the principle of pairs of analogues and divided into three groups of 20 heads each. The conditions of keeping, feeding and water supply of animals of the experimental and control groups were the same, the only difference was that the experimental groups received the feed additive Bacell-MT, the control group received a basic diet. It was found that the use of Bacell-MT contributes to the safety of livestock, normalization of biochemical parameters of blood, improvement of the quality of milk and offspring. A recommendation is given for the use of probiotic supplements in dry period diets to prevent metabolic disorders and ensure the health of both cows and their offspring.</p></abstract><trans-abstract xml:lang="ru"><p>Изучена эффективность применения кормовой добавки Бацелл-МТ (микробная масса живых бактерий Bacillus subtilis 945 (В-5225) в количестве не менее - 1×108 КОЕ/г, микробная масса живых бактерий Bacillus amylolique faciens КЛС (В-14047) в количестве не менее - 1×108 КОЕ/г) в рационе сухостойных коров при подготовке их к отелу, а также для повышения продуктивности и улучшения состояния приплода. Исследования проведены на коровах голштинской породы красно-пестрой масти. Коровы подобраны по принципу пар-аналогов и разделены на три группы по 20 голов в каждой. Условия содержания, кормления и поения животных опытных и контрольной групп были одинаковы, разница была только в том, что опытные группы получали кормовую добавку Бацелл-МТ, контрольная группа получала обычный рацион. Установлено, что применение Бацелл-МТ способствует сохранности поголовья, нормализации биохимических показателей крови, повышению качества получаемого молока и приплода. Дана рекомендация по использованию в рационах сухостойного периода пробиотических добавок для профилактики метаболических нарушений и обеспечения здоровья как коров, так и их потомства.</p></trans-abstract><kwd-group xml:lang="en"><kwd>cattle</kwd><kwd>milk</kwd><kwd>probiotic supplements</kwd><kwd>cow productivity</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>крупный рогатый скот</kwd><kwd>молоко</kwd><kwd>пробиотические добавки</kwd><kwd>продуктивность коров</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Van Saun RJ.
