Free-Stall Use and Preferences in Dairy Cows: A Case Study on Neck Rails Covered by Foam
Bibliographic record
Abstract
This study tested the effect of neck rails equipped with and without foam on stall usage and preference by dairy cows. The hypothesis of the experiment, that cows prefer lying stalls with foam in comparison to stalls without foam, was rejected. There was no significant difference (p > 0.05) in lying time and time spent standing with two and four hooves in the lying stalls between the two treatment groups. Considering the time of individual stall occupation and the distribution of stalls in the pen, cows showed a preference for one of two lying stall rows. Analysis of variance showed a significant difference (p < 0.001) between the time of stall occupation for the two different rows in the pen, including the time spent lying and the time spent standing with two and four hooves in the stall. Lying time per stall in the preferred row (near the feeding alley) in comparison with the alternative row was 580 ± 101 min·d−1·stall−1 versus 50 ± 28 min·d−1·stall−1, respectively. These results can support a design process for new barns with a free-stall housing system for dairy cattle.

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.
