Abstract
This study was conducted to evaluate bioefficacy of dietary chromium picolinate and chromium yeast on growth performance and blood biochemical in red tilapia, Oreochromis niloticus (Linnaeus). Seven isonitrogenous and isocaloric experimental feeds were prepared (approximately 29% and 3,900 kcal/kg). These diets were supplemented with different sources and levels of dietary chromium: 0.5, 1, 2 and 4 mg/kg of Cr picolinate and 2 and 4 mg/kg of Cr yeast and one control group, all groups were arranged triplicate. After a 60-day feeding experiment, specific growth rate (SGR), feed efficiency ratio (FER) and feed utilization were observed. Blood biochemistry consisted of serum total protein, glucose, insulin, cholesterol, triglycerides, high-density lipoprotein (HDL) and low-density lipoprotein (LDL) were measured. Chromium distribution in several organs and glucose tolerant test were measured. The result shows that CrPic of 1 mg/kg and CrYst of 2 mg/kg produced the best SGR (2.91 ± 0.03% and 2.91 ± 0.04%), improved insulin sensitivity (7.30 ± 2.96 and 1.70 ± 0.78 μIU/ml) and increased glucose utilization. CrYst supplementation of 2 mg/kg feed resulted in the highest FER (0.79 ± 0.01) and the lowest triglycerides (126.24 ± 12.36 mg/dl). In conclusion, dietary chromium picolinate at 1 mg/kg or chromium yeast at 2 mg/kg significantly improved bioefficacy on growth performance and blood biochemicals in red tilapia.

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 it
