Abstract
Abstract Two experiments were conducted to determine the standardized ileal digestibility (SID) of AA (Exp. 1) and available energy (Exp. 2) in two black soldier fly larvae meal (BSFLM) sources [full fat (FF) and defatted (DF)] for growing pigs. Two corn starch-based diets were formulated with FF and DF BSFLM as the sole sources of AA. A nitrogen-free diet was also used and the corn starch:sucrose:oil ratio was kept constant among diets to calculate digestible energy. In Exp. 1, 8 ileal-cannulated barrows (25.1±0.41 kg initial BW) were used in a replicated 2 x 2 Latin square design (n = 8). In each period, pigs were adjusted to diets for 5d followed by 2d of continuous ileal digesta collection for 8 h. The SID of AA were calculated using basal endogenous losses for pigs fed a nitrogen-free diet. In Exp. 2, 8 barrows (23.4±0.54 kg initial BW) were used in a partially replicated Latin square design (n=8). In each period, pigs were adjusted to diets for 7d, followed by 5d of total urine and fecal grab sample collection, and 24hr in indirect calorimetry chambers to determine heat production. The SID of Arg, Val, Ala, and Pro tended to be less, and the SID of Met tended to be greater for the FF versus the DF BSFLM (P=0.034, 0.090, 0.053, 0.065, 0.074, respectively). Digestible, metabolizable, and net energy (4101 vs 3257±224 kcal/kg) were greater for the FF versus the DF BSFLM (P< 0.05). The ATTD of phosphorus, neutral detergent fiber, and acid detergent fiber were greater for the FF versus the DF BSFLM (P< 0.05). In conclusion, the SID AA in FF and DF BSFLM were high and similar to those of soybean meal. The FF BSFLM is a better source of available energy for growing pigs compared to DF BSFLM.

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
