DISPOSITION OF SULFADIMETHOXINE IN MALE LLAMAS (LLAMA GLAMA) AFTER SINGLE INTRAVENOUS AND ORAL ADMINISTRATIONS
Bibliographic record
Abstract
This study determined the disposition of sulfadimethoxine in six, healthy, adult, gelded male llamas (Llama glama) by using a nonrandomized crossover design with i.v. dosing (58.8 +/- 3.0 mg/kg based on metabolic scaling) followed by oral dosing (59.3 mg/kg +/- 8.3). Blood samples were collected intermittently for a 72-hr period, and serum sulfadimethoxine concentrations were quantified using high-performance liquid chromatography. Serum sulfadimethoxine concentrations across time were subjected to standard pharmacokinetic analysis based on linear regression. Mean maximum serum concentration after oral dosing was 23.6 +/- 14.9 microg/ml, and extrapolated peak concentration after i.v. administration was 246.6 +/- 15.8 microg/ml. Total clearance of sulfadimethoxine was 45.4 +/- 13.9 L/kg. Half-lives after i.v. and oral administration were 541 +/- 111 min and 642.4 +/- 204.8 min, respectively. Oral bioavailability was 52.6 +/- 15%. These data suggest that the oral dose administered to llamas in this study, based on metabolic scaling from cattle, may be inadequate when compared with the reported minimum inhibitory concentration (512 microg/ml) breakpoint for sulfadimethoxine.

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.
