The effect of fasting on gastrointestinal motility in healthy dogs as assessed by sonography
Bibliographic record
Abstract
OBJECTIVE: To evaluate the effect of fasting on gastrointestinal (GI) motility in healthy dogs, as detected by 2D ultrasound. DESIGN: Prospective observational study. SETTING: University Distributed Veterinary Learning Community. ANIMALS: Ten healthy client-owned dogs. INTERVENTIONS: Dogs were fasted 24 hours following regular feeding. After this first feeding and during the 24 hour fasting period, 2D ultrasound was performed to detect sonographically visible GI contractions of the stomach, duodenum, and jejunum/ileum at T = 30 minutes, 6 hours, 12 hours, and 24 hours. Dogs were then fed a second meal after the 24-hour fast and ultrasound was repeated 30 minutes later (T = 24.5 h). Each site was scanned twice at each time point. Each scan lasted 3 minutes. The results were averaged and then divided by 3 to determine contractions per minute. One-way repeated measures ANOVA with post hoc Tukey's comparison test was used to detect statistical differences over time for each site examined. MEASUREMENTS AND MAIN RESULTS: The mean GI contraction rates in the stomach, duodenum, and jejunum/ileum at T12 and T24 were significantly lower than the GI contraction rates at T30, T3, T6, and T24.5 (P < 0.05). The mean GI contraction rates in the stomach, duodenum, and jejunum/ileum at T30, T3, T6, and T24.5 were not statistically different from each other. CONCLUSIONS: Results of this study show that 2D sonography can be used to evaluate GI motility in dogs and that GI contraction rate decreases significantly in the stomach, duodenum, and jejunum/ileum after 12-24 hours of fasting.

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.
