Evaluation of plasma biotin, folate, and vitamin B<sub>12</sub> concentrations of Holstein dairy cows fed adequate or high concentrations of dietary vitamin D<sub>3</sub>, vitamin E, calcium, and selenium under heat stress
Bibliographic record
Abstract
The aim of this study was to determine plasma biotin (B8), folate (B9), and vitamin B12 (B12) concentrations of multiparous dairy cows under heat stress (HS) fed with adequate or high concentrations of vitamin D3 (VITD) and E (VITE), Ca, and Se. Twelve multiparous Holstein cows were used in a split-plot design. The main plot was: (1) Adequate VITE and Se; (2) High VITE and Se. Within each main plot, cows were assigned to treatments: (1) HS with adequate concentrations of VITD and Ca; (2) HS with high concentrations of VITD and Ca; (3) pair-feeding (PF) with HS in thermoneutrality with adequate concentrations of VITD and Ca in a duplicated 3 × 3 Latin square. There were no treatment effects on plasma B8 and B12. Plasma B9 was lower by 21% for HS with adequate VITD and Ca than PF cows. Results suggested that HS might modify folate status in dairy cows, regardless of treatments.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
