Association Between Standing and Lying Behavior and Udder Health in Free-stall Housed, Lactating Dairy Cows
Bibliographic record
Abstract
This thesis investigates the relationship between cow lying behavior and udder health in free-stall housed dairy cows milked 3x/d. Two longitudinal studies were undertaken; in the first, associations with risk of elevated somatic cell count (eSCC) were determined and, in the second, associations between management practices, post-milking standing duration (PMSD), and risk of intramammary infection (IMI) were determined. A PMSD of >90 min was associated with reduced odds of eSCC. A PMSD of 90 to 120 min was associated with reduced odds of CNS IMI, as was provision of feed around time of milking. Providing ample feed bunk space, having lower free-stall stocking densities, and providing feed around the time of milking promoted PMSD. Overall, these results suggest that management practices which promote PMSD may help to improve udder health in free-stall cows milked 3x/d.

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.
