Myoelectrical activity of gastric antrum in conscious piglets around weaning
Bibliographic record
Abstract
We investigated gastric myoelectrical activity in piglets around weaning. The study was carried out on the same piglets before and after weaning. Before weaning, the piglets were kept with their littermates and nursed by the sow, then they were weaned on solid dry food (standard concentrate for weaning pigs) and fed three times a day. Gastric myoelectrical activity was recorded in conscious animals using bipolar electrodes implanted on the wall of the terminal antrum. A cyclic activity pattern of the antral region in the stomach was present in both suckling and weaned piglets and consisted of quiescence and an activity phase. Sow's milk under nursing conditions significantly decreased the frequency of response potentials in ERA (electrical response activity). However, milk did not influence the basic electrical rhythm (BER) i.e., frequency of ECA (electrical control activity) and did not affect the periodicity of the cyclical activity. After weaning, ingestion of solid feed increased the BER, the frequency of ERA and the frequency of response potentials of ERA and slightly affected the periodicity of the cyclical activity. Key words: Gastric terminal antrum, piglet, weaning, electromyography

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.
