Abstract

fetched live from OpenAlex

Исследования проводили с целью изучения племенной ценности быков-производителей различного происхождения, используемых на племенном поголовье коров черно-пестрой породы Вологодской области. Работа проведена на основе данных ИАС «Селэкс» по 274 быкам-производителям черно-пестрой и голштинской пород, полученных в различных странах мира и используемых на поголовье 33650 коров племенных хозяйств Вологодской области. Применялись общенаучные методы исследования: монографический, статистический, визуализации данных. Установлено, что используемые быки-производители получены в 6 странах мира: США, Канада, Германия, Нидерланды, Дания и Россия. По среднему количеству дочерей на одного быка интенсивнее в популяции используются производители из Канады - 161, Германии - 159 и России - 135. Определено, что в подконтрольной популяции фактор «страна происхождения быка» имеет достоверное (P< 0,01) умеренной силы влияние на племенную ценность производителей по надою материнских предков (η2 = 0,26). Максимальные показатели племенной ценности имеют быки из Канады и США - 14925 кг, 14284 кг, соответственно. У отечественных быков племенная ценность по надою материнских предков составила 11358 кг молока, что на 3567 кг меньше, чем у производителей из Канады (P ≤0,001). В числе 20 быков-производителей, имеющих лучшие показатели племенной ценности по надою материнских предков, 8 быков отечественного происхождения, 6 - из США, 4 - из Канады и по одному из Дании и Нидерландов. Племенная ценность по надою материнских предков этих быков варьирует от 15353 кг до 21480 кг. Полученные результаты исследований будут использованы при определении степени реализации потенциала быков и их оценке по потомству в стадах племенных хозяйств Вологодской области. The research was carried out to study the breeding value of bulls of different origin used in breeding stock of Black-and-White breed of the Vologda region. Work is carried out on the basis of data of IAS "Seleks" on 274 bulls of Black-and-White and Holstein breed, domestic and foreign selection used on a livestock of 33650 cows of breeding farms of the Vologda region. General scientific research methods are used: monographic, statistical, data visualization. It is established that the used bulls are obtained in 6 countries: USA, Canada, Germany, Netherlands, Denmark and Russia. The number of daughters per bull is more intensive in the population using sires from Canada - 161 heads, Germany - 159 heads and Russia - 135 heads. It is determined that in the controlled population the factor "country of origin of the bull" has a significant (P<0.01) moderate force influence on the breeding value of producers by milk yield of maternal ancestors (η2 = 0.26). The maximum indicators of breeding value are bulls from Canada and the United States - 14925 kg, 14284 kg, respectively. In domestic bulls, the breeding value of the milk yield of maternal ancestors was 11358 kg of milk, which is 3567 kg less than that of sires from Canada (P ≤ 0.001). Among the 20 bulls with the best indicators of breeding value on the yield of maternal ancestors, 8 bulls were of domestic origin, 6 from the United States, 4 from Canada and 1 from Denmark and the Netherlands. The breeding value of the milk yield of the maternal ancestors of these bulls varies from 15353 kg to 21480 kg. The results of the research will be used to determine the degree of realization of the potential of bulls and their evaluation of the offspring in the herds of breeding farms of the Vologda region.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
