The behaviour of early-weaned piglets following transport: Effect of season and weaning weight
Bibliographic record
Abstract
Two groups of 48 Cotswold piglets were weaned at 17 ± 1 d of age and assigned to road or simulated transport during summer or winter. Following transport (0, 6, 12 or 24 h), piglets were grouped by weaning weight (light, medium and heavy) in pens of four. Piglet behaviour was recorded on days 1–4, 7 and 14 after weaning and transport. As transport duration increased, drinking behaviour increased (P < 0.05). Control (0 h) piglets fed less (1.5%) than transported piglets (3.1%) during the first 3 d in housing. Significant differences were observed on days 2 and 3 only (P < 0.02). Across season and transport treatment, heavy piglets spent more time fighting (P < 0.005) during the first day in housing, and less time feeding (P < 0.05) during the first 3 d in housing compared with light and medium piglets. During the first 3 d in weanling pens, piglets spent less time feeding following road transport (2.4%) than following simulated transport (2.9%, P < 0.05). Piglets transported by road also spent more time engaged in oral/nasal behaviour during the first 3 d in housing compared with simulated transport groups, although this reached significance on day 3 only (P < 0.05). These results suggest that transport of early-weaned piglets may exacerbate the stress of weaning through additional stress related to factors associated with truck movement, such as noise and vibration, and by imposing an increased risk of dehydration following long journeys (> 12 h).

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.
