Radiodensity in the central cavity of humeri in high-producing non-commercial laying hens
Bibliographic record
Abstract
1. Line differences in the incidence of the presence of radiodense material in the central cavities of humeri of 6 different lines of laying hens were observed using radiographs. 2. Internal humeral radiodense material was observed in over 60% of hens in two lines and 18% of hens in two other lines measured at 65 weeks of age. There was no difference in the incidence (15, 16%) between the last two lines observed at 47 weeks of age. 3. In the 4 lines studied at 65 weeks of age the presence of radiodense material was associated with increased humerus dry weight and ash weight in two lines, while percentage-ash was reduced in all 4 lines. 4. Results from this and previous studies suggest that humeral medullary bone could be an appreciable source of variability in experimental data collected to assess skeletal health.

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.
