Influence of hour of weaning on endocrine changes and rebreeding performance of sows
Bibliographic record
Abstract
Two trials were conducted to determine the effect of hour of weaning on endocrine changes, weaning-to-estrus interval (WEI), and rebreeding performance of sows. A total of 84 Cotswold sows of mixed parity were used in a completely randomized design. Sows were maintained in a cycle of 9h light: 15h dark from day 105 of gestation. After an 18-day lactation sows were weaned at either 0800h (AM; immediately after lights-on) or 1645h (PM; immediately before lights-off). Eighteen sows were fitted with indwelling ear-vein catheters on the day before weaning. Sera, from blood samples taken at 30-minute intervals from the day of weaning to the second day of standing estrus, were analyzed for luteinizing hormone (LH), estradiol, and progesterone. All sows were monitored for WEI, synchronization of post-weaning estrus, pregnancy, and subsequent farrowing performance. Sows were naturally inseminated on the first day of estrus followed by AI at approximately 10 and 24h. (Abstract shortened by UMI.)

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.
