HORMONAL STATUS AND REPRODUCTIVE FUNCTION OF HEREFORD CATTLE CANADIAN AND SIBERIAN BREEDING
Bibliographic record
Abstract
The process of adaptation of imported cattle to new technological and climatic conditions leads to morphological and functional restructuring of the body, which may cause a violation of reproductive function. In the article deals the dynamics of adrenal hormones (cortisol), thyroid (thyroxine, triiodothyronine) and evaluated reproductive function in beef Hereford cattle Canadian selection in the conditions of the Altai Territory. Our study was carried out under production conditions farm «Farm» in the Tselinskiy district of the Altai Territory in the period from 2012 to 2013. The object of the study were heifers Hereford breed of Canadian selection at the age of 11 to 16 months (n = 97). It was found that because of the high levels of cortisol in the initial phase of adaptation fertilizing the capacity of Canadian heifers was lower than those analogs Siberian breeding on 12.4% . The majority of imported non-pregnant animals had a persistent corpus luteum and ovarian hypofunction. Further adaptation of imported animals and the development of their pregnancy was accompanied by increased functional activity of the adrenal cortex and the high metabolism of thyroid hormones. Indicators of reproductive function in cows, heifers Canadian and Siberian breeding after giving birth were not significantly different.

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; a candidate call from one teacher head, not a consensus.
