Physiological and behavioural responses to short-haul transport by stock trailer in finished steers
Bibliographic record
Abstract
Nineteen British cross-bred steers (623 ± 10.6 kg) were transported in groups of four or five for 3 h and returned to their home pens. Jugular cannulas, heart rate (HR; BPM) monitors and radio transmitters were used to non-invasively collect physiological data. Heart rate (n = 13) was lower during highway travel (83.5 ± 3.15, P > 0.05) compared with pre-loading (118.9 ± 3.19, P < 0.01) and off-loading (97.5 ± 4.47) but was not different from travel in town (88.8 ± 2.90). Plasma cortisol concentration (µg dL -1 , n = 16) increased from pre-loading (1.87 ± 0.28) to off-loading (3.10 ± 0.28, P < 0.02) and decreased to 1.16 ± 0.28 µg dL -1 by 1 h after off-loading (P < 0.001), a value not different from pre-loading levels. Body temperature measured at offloading was 0.19°C higher (P < 0.001) than at pre-loading. No differences in the time spent eating and ruminating were observed when compared between a 1-h period 1 d prior to transport and the same time of day post-transport (P > 0.50). Increases in HR (P < 0.01) and lying time (P < 0.001) post-transport compared with the days prior suggest cattle experienced some fatigue. Mild, short-term stress responses were observed in finished steers exposed to 3 h of transportation. Key words: Cortisol, heart rate, hematocrit, behaviour, steers, transportation

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.
