Savaging behaviour in domestic gilts: A study of seven commercial farms
Bibliographic record
Abstract
Piglet-directed aggression at farrowing was investigated on seven large, new pig units. Gilts were subject to a light (continuous or diurnal light) and/or sound (newborn piglet vocalisations or no vocalisations) treatment around the time of farrowing. Behaviour records were collected for the first farrowing of 6625 crossbred gilts. The incidence of savaging, number of piglets affected by it and factors associated with piglet-directed aggressive behaviour were recorded. Piglet-directed aggression was scored as 0 (none), 1 (moderate) or 2 (severe). Effects of the light and sound treatments, situation of the farrowing crate within the farrowing room and time (from first to fourth fill of the farrowing rooms) were examined. Three hundred and thirty-one gilts (5.3%) displayed some degree of aggression towards their piglets (scoring either 1 or 2), while 201 (2.9%) killed piglets.

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.
