Abstract
We previously reported that high levels (≥50%) of black soldier fly larvae meal (BSFLM) reduced growth and altered organs morphology in broiler chickens. Herein we further examined gastrointestinal, breast, bone, plasma, and litter attributes in broiler chickens fed partial to complete replacement of soybean meal (SBM) with BSFLM. A total of 1152 day-old Ross × Ross 708 male chicks ( n = 8) were allocated to 48 pens and assigned one of six diets: a basal corn-SBM diet (0BSFLM), four diets in which SBM in 0BSFLM was replaced with BSFLM at 12.5%, 25%, 50%, and 100% (12.5BSFLM, 25BSFLM, 50BSFLM, and 100BSFLM) and a final diet (0 + AGP) in which 0BSFLM was fed with coccidiostat and antibiotic. Birds were bled for plasma and necropsied for samples. Litter samples were collected on days 45 to 47. Breast weight, woody breast, and hardness scores and tibia morphometry reduced linearly in response to BSFLM inclusion ( P < 0.001). BSFLM linearly increased plasma Lys, Met, Thr, uric acid, creatine kinase and decreased Arg and potassium ( P < 0.05). Litter ammonium nitrogen and potassium decreased linearly in response to BSFLM ( P < 0.001). In conclusion, the data suggested physiological and metabolic inefficiencies in broiler chickens fed isocaloric and isonitrogenous diets with ≥50% BSFLM replacement of SBM.

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
