Abstract
Abstract The primary goal was to investigate the effects of l -carnitine on fuel efficiency, as an antioxidant, and for muscle recovery in Labrador retrievers. Dogs were split into two groups, with one group being supplemented with 250 mg/d of Carniking™ l -carnitine powder. Two experiments (Expt 1 and Expt 2) were performed over a 2-year period which included running programmes, activity monitoring, body composition scans and evaluation of recovery using biomarkers. Each experiment differed slightly in dog number and design: fifty-six v . forty dogs; one endurance and two sprint runs per week v . two endurance runs; and differing blood collection time points. All dogs were fed a low-carnitine diet in which a fixed amount was offered based on maintaining the minimum starting weight. Results from Expt 1 found that the carnitine dogs produced approximately 4000 more activity points per km compared with the control group during sprint ( P = 0·052) and endurance runs ( P = 0·0001). Male carnitine dogs produced half the creatine phosphokinase (CPK) following exercise compared with male control dogs ( P = 0·05). Carnitine dogs had lower myoglobin at 6·69 ng/ml following intensive exercise compared with controls at 24·02 ng/ml ( P = 0·0295). Total antioxidant capacity (TAC) and thiobarbituric acid reactive substance (TBARS) results were not considered significant. In Expt 2, body composition scans indicated that the carnitine group gained more total tissue mass while controls lost tissue mass ( P = 0·0006) and also gained lean mass while the control group lost lean mass ( P < 0·0001). Carnitine dogs had lower CPK secretion at 23·06 v . control at 28·37 mU/ml 24 h after post-run ( P = 0·003). Myoglobin levels were lower in carnitine v . control dogs both 1 h post-run ( P = 0·0157; 23·83 v . 37·91 ng/ml) and 24 h post-run ( P = 0·0189; 6·25 v .13·5 ng/ml). TAC indicated more antioxidant activity in carnitine dogs at 0·16 m m v . control at 0·13 m m ( P = 0·0496). TBARS were also significantly lower in carnitine dogs both pre-run ( P = 0·0013; 15·36 v . 23·42 µ m ) and 1 h post-run ( P = 0·056; 16·45 v . 20·65 µ m ). Supplementing l -carnitine in the form of Carniking™ had positive benefits in Labrador retrievers for activity intensity, body composition, muscle recovery and oxidative capacity.

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 it
