Behaviour of piglets weaned at three or six weeks of age
Bibliographic record
Abstract
The objective of this experiment was to compare behaviour of piglets weaned and mixed at 21±1 (W21, n=81) or 43±1 (W43, n=70) days of age. Piglets were observed two days before weaning (D-2), just after weaning and mixing (D0) and 24 hours later (D1). Time spent feeding was lower on D0 compared to D1 in both treatment, but was lower in W21 than in W43 piglets (P<0.05). On D0, W21 piglets were less active than W43 piglets (P<0.001). Accordingly, between D-2 and D0, W43 piglets increased (P<0.001) time spent in aggression, exploration and locomotion. Conversely, W21 piglets were more active than W43 piglets on D1 (P<0.01). Timing of behaviour relative to weaning day differed between treatments; W21 piglets were more apathetic than W43 piglets just after weaning indicating a delay in the reaction of younger piglets to weaning and mixing. W21 piglets also had a greater and longer decrease in post-weaning eating incidence than W43 piglets, which is likely due to both older age and previous creep feed experience.

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.
