Работа выполнена в СХПК «Племзавод им. Ленина» Атнинского района Республики Татарстана и лаборатории отдела физиологии, биохимии, генетики и питания животных ТатНИИСХ ФИЦ КазНЦ РАН. Генотипирование осуществляли методом ПЦРПДРФ по локусу гена OPN-Bse1 I. Анализ генетической структуры показал, что исследуемая популяция полиморфна по гену OPN. Распределение аллелей и генотипов было следующим: С-0,432 и Т-0,568; CC – 14,3% (37 гол.), CT – 57,8% (149 гол.) и TT – 27,9% (72 гол.). Наибольший удой за 305 дней лактации и высокий выход молочного белка отмечен у особей с генотипом CC. В ходе ДНК-тестирования 258 коров-первотелок голштинской породы методом ПЦР-ПДРФ полиморфизма гена остеопонтин (OPN) выявлено, что исследуемая популяция крупного рогатого скота полиморфна и представлена всеми аллелями и генотипами. По содержанию массовой доли жира и выходу молочного жира статистически значимое превосходство наблюдается у животных с гетерозиготным CT-генотипом. Установлено, что аллель С оказывает положительное влияние на признаки молочной продуктивности и качественного состава молока.</p></abstract><trans-abstract xml:lang="en"><p>The study was conducted in order to study the polymorphism of the osteopontin gene (OPN) and to evaluate the indicators of milk productivity of Holstein first-calf cows with different genotypes. The work was carried out in the agricultural complex "Plemzavod im. Lenin" of the Atninsky district of the Republic of Tatarstan and the laboratory of the Department of Physiology, Biochemistry, Genetics and Animal Nutrition of the TatNIISKh FIT KAZNTS RAS. Genotyping was carried out by PCR-PDRF at the locus of the OPN-Bse1 I gene. The analysis of the genetic structure showed that the studied population is polymorphic by the OPN gene. The distribution of alleles and genotypes was as follows: C-0.432 and T0.568; CC – 14.3% (37 goals), CT - 57.8% (149 goals) and TT - 27.9% (72 goals). The highest milk yield for 305 days of lactation and a high yield of milk protein was observed in individuals with the CC genotype. During DNA testing of 258 Holstein firstcalf cows by PCR-PDRF of osteopontin gene polymorphism (OPN), it was revealed that the studied cattle population is polymorphic and is represented by all alleles and genotypes. According to the content of the mass fraction of fat and the yield of milk fat, a statistically significant superiority is observed in animals with a heterozygous CT genotype. It has been established that the C allele has a positive effect on the signs of milk productivity and the qualitative composition of milk.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>крупный рогатый скот</kwd><kwd>ген</kwd><kwd>аллель</kwd><kwd>ПЦР-ПДРФ</kwd><kwd>OPN</kwd><kwd>молочная продуктивность</kwd><kwd>жир</kwd><kwd>белок</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cattle</kwd><kwd>gene</kwd><kwd>allele</kwd><kwd>PCR-RFLP</kwd><kwd>OPN</kwd><kwd>milk production</kwd><kwd>fat</kwd><kwd>protein</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья подготовлена в рамках государственного задания: Эколого-генетические подходы к созданию и сохранению ресурсов растений и животных, расширению их адаптивного потенциала и биоразнообразия, разработка сберегающих агротехнологий с целью повышения устойчивости производства высококачественной продукции, достижения безопасности для здоровья человека и окружающей среды.
