Abstract
Cobalamin analogues in samples of rumen fluid, duodenal and ileal digesta and faeces of lactating dairy cows collected during the course of two nutritional studies were identified using a recently developed liquid chromatography-mass spectrometry method in order to determine if changes in diet composition could alter their proportions. Only cobalamin and cobinamine were detected in feedstuffs; six supplementary analogues were detected in the gastrointestinal tract content. The proportion of analogues produced by the gastrointestinal microflora was higher than the vitamin itself. The mode of conservation of forage had no effect on the proportion of analogues in rumen fluid, duodenal digesta and faeces, whereas increasing metabolisable protein supply raised the proportion of analogues reaching the duodenum (p = 0.008). The proportion of analogues was higher in ileal than duodenal digesta, this observation probably indicates a preferential absorption of cobalamin in the small intestine. The present results showed that changes in diet composition could alter cobalamin synthesis in rumen.

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 it
