Однако требуется интенсифицировать работы по установлению норм для основных биохимических (БХ) параметров крови товарных гибридов свиней, что явилось главной целью работы. Исследования проводились на хряках следующих групп: 1) породы дюрок на 60-65 день откорма (n=12), 2) гибридах дюрок˟ландрас˟крупная белая (F2) на 60-65 день откорма (n=19), 3) породы дюрок на 100-110 день откорма (n=18) и 4) гибридах дюрок˟ландрас˟крупная белая (F2) на 100-110 день откорма (n=27). Образцы крови брали из ушной вены в вакуумные пробирки с активатором свертывания крови для БХ-анализа и центрифугировали (15 мин. при 3000 об/мин.). БХ-анализ выполнен на анализаторе «ChemWell» (Awareness Technology, США). Концентрации аминокислот в сыворотке крови определяли методом ионообменной хроматографии на «ВЭЖХ LC-20 Prominence» (Shimadzu, Япония) с фирменной колонкой и модулем для пост-колоночной дериватизации нингидрином «АРМ-1000» (Sevko&amp;Co, Россия). Подготовка проб для анализа проводили по ГОСТ 32195-2013. Положительно, что основные белковые показатели крови у свиней породы дюрок и их гибридах F2 в разных возрастных группах являются достаточно стабильными, о чём свидетельствуют низкие и умеренные коэффициенты вариации (CV&lt;20%). Показано, что с увеличение сроков откорма усиливаются тенденции к интенсификации всех видов обмена веществ, о чем свидетельствуют многочисленные корреляций между биохимическими и аминокислотными параметрами крови хряков групп 3 и 4 на момент окончания откорма (100-110 дней) по сравнению с группами 1 и 2 (период в 60-65 дней). Авторы считают, что установление связей между биохимическими параметрами крови свиней, с одной стороны, и их породными особенностями, и длительностью откорма, с другой стороны, имеет большое фундаментальное и практическое значение.</p></abstract><trans-abstract xml:lang="en"><p>In the last decade, significant progress has been achieved in pork production and Russian pig farming in general. However, it is necessary to intensify work on establishing standards for the main biochemical (BC) parameters of the blood of commercial pig hybrids, which was the main goal of the work. The studies were conducted on boars of the following groups: 1) Duroc breed on the 60-65th day of fattening (n=12), 2) F2 Duroc˟Landrace˟Large White hybrids on the 60-65th day of fattening (n=19), 3) Duroc breed on the 100-110th day of fattening (n=18) and 4) F2 Duroc˟Landrace˟Large White hybrids on the 100-110th day of fattening (n=27). Blood samples were taken from the ear vein into vacuum tubes with a blood coagulation activator for biochemical coagulation analysis and centrifuged (15 min at 3000 rpm). Biochemical coagulation analysis was performed on a ChemWell analyzer (Awareness Technology, USA). Amino acid concentrations in blood serum were determined by ion-exchange chromatography on a HPLC LC-20 Prominence (Shimadzu, Japan) with a proprietary column and a module for post-column derivatization with ninhydrin ARM-1000 (Sevko&amp;Co, Russia). Samples for analysis were prepared according to GOST 32195-2013. It is positive that the main protein indices of blood in Duroc pigs and their F2 hybrids in different age groups are quite stable, as evidenced by low and moderate variation coefficients (CV&lt;20%). It is shown that with an increase in the fattening period, the tendencies to intensify all types of metabolism increase, as evidenced by numerous correlations between the biochemical and amino acid parameters of blood of boars of groups 3 and 4 at the end of fattening (100-110 days) compared to groups 1 and 2 (a period of 60-65 days). The authors believe that establishing relationships between the biochemical parameters of pig blood, on the one hand, and their breed characteristics and fattening duration, on the other hand, is of great fundamental and practical importance.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>свиноводство</kwd><kwd>чистопородные свиньи</kwd><kwd>гибриды F2</kwd><kwd>биохимия крови</kwd><kwd>аминокислотный анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pig breeding</kwd><kwd>purebred pigs</kwd><kwd>F2 hybrids</kwd><kwd>blood biochemistry</kwd><kwd>amino acid analysis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа по разделам «Введение», 1 и 2 «Результаты и обсуждения» выполнена при финансовой поддержке Российского научного фонда, грант №20-16-00032-П (соглашение №20-16-00032-П от 15.05.2023 г.) https://rscf.ru/project/20-16-00032/.
