Injection of neonatal piglets with dexamethasone stimulates leptin mRNA expression and reduces the stress response in market weight pigs
Bibliographic record
Abstract
Abstract Neonatal piglets were given three daily injections of dexamethasone at 1 mg/kg body weight to examine if their stress response and carcass fat distribution at a 120-kg market weight could be altered. The daily acute injections tended to increase the amount of muscle and adrenal leptin mRNA expression (P < 0·1) for 1 and 3 days after the end of the treatment but had no effect on the amount of glucocorticoid receptor mRNA. The treated animals had a 19% lower adult stress response to transport than the controls as measured by salivary cortisol levels. There was no significant change in the treated animals’ carcass and meat quality traits at market weight. However, a trend towards more marbling fat and carcass backfat were seen in the dexamethasone treated pigs at market weight.

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.
