Dietary Supplements to Support Dairy Calf Health and Welfare
Bibliographic record
Abstract
The objective of this dissertation was to investigate if dietary supplements could improve dairy calf health and welfare. The first study was focused on investigating the effects of Echinacea purpurea (EP) supplementation on markers of immunity, health, feed intake, and growth of dairy calves. Overall, EP supplementation was associated with blood markers indicative of reduced inflammation and stimulated immunity, with minor benefits to health and growth. The second study was focused on how weaning, as well as supplementing calves with tyndallized Lactobacillus helveticus (TLH), affects behavioral and physiological indicators of dairy calf affective state. Overall, there were changes in the behavior of calves at weaning that were indicative of a more negative affective state. Supplementation of TLH was associated with indicators of a more negative affective state, especially during weaning. In summary, this research provides novel information on the effects of dietary supplements on dairy calf health and welfare.

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.
