Вопрос изучения процессов обмена веществ является актуальным не только для коров, но и для быков-производителей, поскольку позволяет выявлять различные заболевания на ранних стадиях. Работа посвящена изучению биоэлементного состояния быков-производителей после длительного зимнего периода эксплуатации на раннем этапе весеннего сезона в условиях Пермского края.Методы. Исследования проведены на 25 быках-производителях голштинской породы черно-пестрой масти , возраст которых варьировал от 2 до 10 лет. Был изучен белково-липидный, минеральный обмен и ферментативная активность организма животных.Результаты. Выявлено, что превышение нормы имелосьтолько по содержанию билирубина — на уровне 16%. Установлено, что среди животных были особи, имевшие наивысшие индивидуальные показатели по некоторым позициям. В группе животных с уровнем нормальных и повышенных конценраций билирубина выявлено отличие разницы по щелочной фосфотазе на 23,0%, соотношению А/Г — на 11,0%, по общему белку и глобулину — на 4,5 и 8,3% соответственно. Исследования животных с учетом содержания щелочной фосфатазы в сыворотке крови у быков-производителей в норме и выше нормативных значений показали, что ее концентрация имеет существенную роль (при Р &lt; 0,001). У молодых быков (30 мес.) этот показатель был статистически достоверным и его значения были выше, чем у животных 5 лет и старше. Стоит также отметить, что у взрослых быков уровень общего билирубина был повышен на 25%, разница в соотношении А/Г между группами животных составила 30,0%, общего белка — 12,0%, глобулина — 12,4% и альбумина — 15,4%. С учетом проведенных исследований можно сказать, что необходимо проводить биохимический мониторинг всего поголовья стада.</p></abstract><trans-abstract xml:lang="en"><p>Relevance. The issue of studying metabolic processes is relevant not only for cows, but also for breeding bulls, due to the fact that it allows to identify various diseases in the early stages. The work is devoted to the study of the bioelemental state of breeding bulls after a long winter period of operation at an early stage of the spring season in the conditions of the Perm TerritoryMethods. The studies were carried out on 25 breeding bulls of the Holstein breed of black-and-white color, whose age varied from 2 to 10 years. The protein-lipid, mineral metabolism and enzymatic activity of the animal organism was studied.Results. It was revealed that only the content of bilirubin had an increased level in relation to the norm —at the level of 16%. It was established that among the animals there were individuals who had the highest individual indicators for some positions. In the group of animals with normal and elevated concentrations of bilirubin, a difference was found in the difference in alkaline phosphatase by 23.0%, the A/G ratio —by 11.0%, in total protein and globulin — by 4.5 and 8.3% respectively. Animal studies, taking into account the content of alkaline phosphatase in the blood serum of breeding bulls in the norm and above the standard values, showed that its concentration plays a significant role (at P &lt; 0.001). In young bulls (30 months), this indicator was statistically significant and its values were higher than in animals of5 years and older. It is also worth noting that in adult bulls the level of total bilirubin was increased by 25%, difference in ratio of A/Gbetween groups of animals was 30.0%, total protein — 12.0%, globulin — 12.4% and albumin —15.4%. Based on the studies carried out, it can be said that it is necessary to conduct biochemical monitoring of the entire herd.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биоэлементное состояние</kwd><kwd>длительный зимний период</kwd><kwd>щелочная фосфатаза</kwd><kwd>концентрация билирубина</kwd><kwd>быки-производители</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bioelemental state</kwd><kwd>long winter period</kwd><kwd>alkaline phosphatase</kwd><kwd>bilirubin concentration</kwd><kwd>breeding bulls</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">Владимиров В.Л., Самохин В.Т., Науменко П.А., Рыжков В.А., Бадалов Я.М., Фридберг Р.В., Бодров Д.А.
