ПЛЕМЕННАЯ ОЦЕНКА БЫКОВ-ПРОИЗВОДИТЕЛЕЙ ЗАРУБЕЖНОЙ СЕЛЕКЦИИ
Bibliographic record
Abstract
В статье представлен анализ завезенной в 2019 году спермопродукции племенных быков-производителей молочного и мясного направления. Ввоз семени чистопородных племенных быков молочного направления составил 3,16 млн. доз, мясного - 52,6 тыс. доз. Лидерами среди поставщиков семени являются США и Канада (31,4…57,7%). Наибольшее количество семени отмечено у быков голштинской породы (3,0 млн. доз). Отмечено увеличение поставок семени быков породы бланк-блю бельж (9,8 тыс. доз). Общий объем сексированного семени составил 412,0 тыс. доз, что на 43,9 % выше, чем в 2018 году. Для анализа использовали опубликованные данные генетической оценки быков 4 пород (голштинская, айрширская, джерсейская, бурая швицкая) за август 2020 года и объемы завозимого семени. В качестве критерия племенной ценности выбран индекс LNM$. Значения индекса LNM$ в голштинской породе варьировали от -854 до +790, в айрширской породе - от -180 до +422, в бурой швицкой породе - от -150 до +393,4 и в джерсейской породе - от +12,3 до +494,4. Проведен анализ генеалогических групп быков от которых был ввезен племенной материал. The article presents an analysis of imported sperm products in 2019 of breeding sires of dairy and meat products. Import of seed of purebred breeding bulls of the dairy direction made 3,16 million doses, meat-52,6 thousand doses. The leaders among seed suppliers are the USA and Canada (31.4...57.7%). The largest number of seeds was observed in Holstein bulls (3.0 million doses). There was an increase in the supply of Blank-Blue Belge seed (9.8 thousand doses). The total volume of sexed semen was 412.0 thousand doses, which was 43.9% higher than in 2018.To analyze breeding evaluations, we used published data from the genetic evaluation of 4 breeds of bulls (Holstein, Ayrshire, Jersey, Brown Swiss) for August 2020 and their volumes of imported seed. The LNM$ index is selected as the breeding value criterion. The values of the LNM$ index in the Holstein breed ranged from -854 to +790, in the Ayrshire breed - from -180 to +422, in the Brown Swiss breed - from -150 to +393.4 and in the Jersey breed-from +12.3 to +494.4. The analysis of genealogical groups of bulls imported breeding material was carried out.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
