Cattle can tolerate high-molybdenum forage grown on reclaimed mine tailings: a review
Bibliographic record
Abstract
Revegetation and cattle production are major objectives in the reclamation plan for mine tailings at the Highland Valley Copper mine in Canada. Residual molybdenum (Mo) in the tailings is imbibed by vegetation and forages accumulate up to 400 ppm Mo at the Highmont tailings pond. Grazing studies with cattle determined the feasibility of utilising the site for livestock production and published results are reviewed. Clinical evaluations (1999–2001) revealed signs of lameness, diarrhoea and hair coat depigmentation in cows but they recovered without treatment. Supplement trials (2002 – 2004) demonstrated the efficacy of copper (Cu) sulphate for the alleviation of clinical disorders. Dietary Mo was rapidly eliminated from the gastrointestinal tract and from muscle and fat tissues. Forages at the site imbibed molybdate but endogenous chelation reduced the toxic effect of the ion. Cu sulphate supplementation alleviated clinical signs, which permitted forage utilisation and sustainable cattle production at Highmont.

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