Методы исследования: модифицированный метод определения церулоплазмина по Ревину; определение меди на атомноадсорбционном спектрометре ZEEnit 650 P (Analytik Jena AG, Германия), аминокислотный анализ с помощью высокоэффективной системы жидкостной хроматографии LC-20 Prominence (Shimadzu, Токио, Япония), оснащенной реакционным модулем постколоночной дериватизации нингидрином ARM-1000 (Sevko &amp; Co., Москва, Россия). Группы для исследования сформированы в зависимости от сроков лактации: 1-2 месяц – 1 группа; 3-5 месяц – 2 группа; 6-7 месяц – 3 группа; 8-9 месяц – 4 группа. В каждую группу вошло по 8 животных. Для статистической обработки полученных результатов применяли U-критерий Манна-Уитни и корреляции Пирсона. Средние значения уровня церулоплазмина в группах составили 0,44-0,49 мг/мл, меди 71-83 мкг/л, гистидина 0,11-013 г/100г, цистеина 0,03 г/100 г и метионина 0,09-0,11 г/100 г. В изучаемых 4 группах обнаружены небольшие различия в содержании церулоплазмина, меди и трех аминокислот, однако только у 2 и 4 групп по гистидину эти различия являются достоверными. Таким образом, указанные интервалы содержания церулоплазмина и меди могут служить важными ориентирами при определении «референтных интервалов» для молока здоровых коров в целом, при этом не обязательно учитывать разные сроки лактации.</p></abstract><trans-abstract xml:lang="en"><p>The purpose of the research was to study the content of ceruloplasmin, copper and copper-coordinating amino acids (in the molecule of the studied protein) in the milk of white-and- black cows at different periods of lactation. The research methods were: modified method for determining ceruloplasmin by Revin; copper was determined using a ZEEnit 650 P atomic adsorption spectrometer (Analytik Jena AG, Germany), amino acid analysis was performed using a highly efficient LC-20 Prominence liquid chromatography system (Shimadzu, Tokyo, Japan) equipped with a reaction module for post-column derivatization with ninhydrin ARM-1000 (Sevko &amp; Co., Moscow, Russia). The study groups were formed depending on the timing of lactation: 1-2 months – group 1; 3-5 months – group 2; 6-7 months – group 3; 8-9 months – group 4. Each group included 8 animals. The Mann-Whitney U criterion and Pearson correlations were used for statistical processing of the obtained results. The average values of ceruloplasmin levels in the groups were 0.44-0.49 mg/ml, copper 71-83 mcg/l, histidine 0.11-013 g/100g, cysteine 0.03 g/100g and methionine 0.09-0.11 g/100g. In these 4 groups, small differences were found in the content of ceruloplasmin, copper and three amino acids, but only for the second and fourth groups of histidine, these differences were significant. Thus, the indicated intervals of ceruloplasmin and copper content can serve as important guidelines for determining the "reference intervals" for cow milk in general, while it is not necessary to take into account different lactation periods.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лабораторная диагностика</kwd><kwd>белки теплового шока с антиоксидантной активностью</kwd><kwd>гистидин</kwd><kwd>метионин</kwd><kwd>цистеин</kwd></kwd-group><kwd-group xml:lang="en"><kwd>laboratory diagnostics</kwd><kwd>heat shock proteins with antioxidant activity</kwd><kwd>histidine</kwd><kwd>methionine</kwd><kwd>cysteine</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнялась при финансовой поддержке Министерства науки и высшего образования РФ в рамках выполнения государственного задания ФГБНУ «Федеральный исследовательский центр животноводства – ВИЖ имени академика Л.
