Injuries, lameness, and cleanliness of sows in four group-housing gestation facilities in Ontario
Bibliographic record
Abstract
This study compared proportion of animals with shoulder and vulvar lesions and scores for cleanliness, body condition, and lameness in sows housed in four different group-housing facilities. Inspectors visited each herd once per month and scored sows for each parameter. All farms housed gestating sows in groups, but pen designs and management differed on each farm. Differences among herds were identified for severity of lameness, vulvar lesions 2 and 3 (small and severe bite wounds), mild shoulder lacerations, and cleanliness scores of 1 (clean) and 3 (hooves and 50% of legs and body soiled). No differences in body condition scores were observed among herds. Newly mixed sows often fight to establish a social hierarchy. In this case study, different herds demonstrated differences in parameters that represent aggressive encounters, ie, degrees of lameness, injury, and cleanliness. Pen design and management factors may be associated with aggressive encounters among newly mixed sows. Different group-housing systems are capable of maintaining acceptable body condition scores in sows.

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.
