Pharmacokinetics of florfenicol in North American elk (<i>Cervus elaphus</i>)
Bibliographic record
Abstract
Florfenicol pharmacokinetics after administration of a single subcutaneous (s.c.) dose of 40 mg/kg of body weight in adult elk (Cervus elaphus) was investigated. Serum florfenicol concentrations were determined by a sensitive high-performance liquid chromatographic method with limit of quantification of 0.03 microg/mL. Florfenicol pharmacokinetic parameters in elk were estimated using a noncompartmental approach. After a single s.c. injection, florfenicol concentrations remained above 1 microg/mL for approximately 36 h and above 0.5 microg/mL for approximately 72 h. Following s.c. injection, florfenicol was absorbed rapidly with a mean maximum concentration (C(max)) of 3.7 microg/mL achieved at 4.2 h (T(max)). The C(max) value in elk is similar to values reported in cattle at the same dose, suggesting that the 40 mg/kg s.c. dose achieves therapeutic concentrations in elk. A mean elimination half-life (t(1/2)) of 44 h is shorter than that reported in cattle. The more rapid elimination half-life in elk suggests that elk may require a multiple dose regimen for therapeutic success with s.c. Nuflor. We recommend s.c. Nuflor be administered subcutaneously to elk every 24 h at a dose level of 40 mg/kg.

How this classification was reachedexpand
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.
