Установлено, что общий фон неспецифической резистентности у животных по проценту лизиса находился на уровне 32,4 ± 0,8, по количеству лизоцима — 0,29 ± 0,01 мкг/мл, по удельным единицам активности белка — 0,81 ± 0,06 мг, по бактерицидной активности сыворотки крови — 25,6 ± 0,86%. Определена взаимосвязь неспецифической резистентности у быков-производителей в зависимости от породы. Состояние быков по обеспеченности общим белком находилось на сравнительно схожем уровне в пределах референсных значений. По уровню процента лизиса сравнительно низкие значения зафиксированы у животных джерсейской породы (24,6%), больше всех — у костромской и бурой швицкой пород (40,3% и 40,5% соответственно). Самый низкий уровень по удельным единицам активности тоже у джерсейской породы. Сравнительно высокий уровень бактерицидной активности сыворотки крови отмечен у айрширской породы (34,2%), у остальных пород бактерицидная активность сыворотки крови находилась на уровне 23,7–26,4%. Отмечены достоверные отличия между голштинской породой черно-пестрой масти и костромской по количеству лизоцима в сыворотке крови, по удельным единицам активности (р ≤ 0,05), с быками джерсейской породы — по удельным единицам активности (р ≤ 0,01), с айрширской — по удельным единицам активности (р ≤ 0,05) и бактерицидной активности сыворотки крови (р ≤ 0,01). Между животными голштинской породы красно-пестрой масти и джерсейской, айрширской породами по ряду показателей достоверность была р ≤ 0,05; между костромской, джерсейской, айрширской и симментальской по общему белку, количеству лизоцима и удельным единицам активности достоверность составила р ≤ 0,01.</p></abstract><trans-abstract xml:lang="en"><p>Research has been conducted to study nonspecific resistance in breeding bulls depending on the breed, age within the breed and the body’s protein supply after a long winter period of operation. It was established that the general background for nonspecific resistance in animals in terms of the percentage of lysis was at the level of 32.4 ± 0.8; by the amount of lysozyme 0.29 ± 0.01 μg/ml; by specific units of protein activity 0.81±0.06 mg; bactericidal activity of blood serum 25.6±0.86%. The relationship between nonspecific resistance in breeding bulls depending on the breed has been determined. The condition of bulls in terms of total protein supply was at a relatively similar level within the reference values. In terms of the percentage of lysis, relatively low values were recorded in animals of the Jersey (24.6%), the highest in the Kostromsky and Brown Swiss — 40.3% and 40.5%, respectively. The Jersey breed also has the lowest level of specific activity units. A relatively high level of bactericidal activity of blood serum was noted in the Ayrshire (34.2%), while in other breeds bactericidal activity of blood serum was at the level of 23.7–26.4%. Significant differences were noted between the Holstein Black and motley color and Kostromsky in the amount of lysozyme in the blood serum, in specific units of activity (р ≤ 0.05), with the Jersey breed in specific units of activity (р ≤ 0.01), and with the Ayrshire breed in specific activity units (р ≤ 0.05) and bactericidal activity of blood serum (р ≤ 0.01). Between the Holstein Red red-and-white color and Jersey and Ayrshire animals, the reliability for a number of indicators was р ≤ 0.05; between the the Kostromsky, Jersey, Ayrshire and Simmental animals for total protein, the amount of lysozyme and for specific units of activity р ≤ 0.01.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>общая резистентность</kwd><kwd>бактерицидная активность сыворотки крови</kwd><kwd>лизоцимная активность сыворотки крови</kwd><kwd>быки-производители</kwd><kwd>общий белок</kwd><kwd>порода</kwd><kwd>возраст</kwd></kwd-group><kwd-group xml:lang="en"><kwd>general resistance</kwd><kwd>bactericidal activity of blood serum</kwd><kwd>lysozyme activity of blood serum</kwd><kwd>breeding bulls</kwd><kwd>total protein</kwd><kwd>breed</kwd><kwd>age</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания при финансовой поддержке фундаментальных научных исследований Минобрнауки РФ по теме FGGN-2024-0014, регистрационный № 124020200127-7.</funding-statement><funding-statement xml:lang="en">The work was carried out within the framework of a state assignment with the financial support of fundamental scientific research from the Ministry of Education and Science of the Russian Federation on the topic FGGN-2024-0014, registration No. 124020200127-7.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Трушкин В.А., Никишина И.В., Ковалев С.П., Воинова А.А., Полевая А.П.
