Standardized ileal digestible amino acids and apparent metabolizable energy content in defatted black soldier fly larvae meal fed to broiler chickens
Bibliographic record
Abstract
Standardized ileal digestibility (SID) of amino acids (AA) and apparent metabolizable energy corrected for nitrogen (AMEn) in defatted black soldier fly larvae meal (BSFLM) were determined in broiler chicks. A total of 180-d-old male broiler chicks (Ross 708) were fed a commercial broiler starter diet to day 13 of age. On day 14, birds were weighed and placed in cages (10 birds per cage; n = 6) and allocated one of two semi-purified cornstarch-based diets. The diets were nitrogen-free diet (NFD) for estimating endogenous AA losses and 20% crude protein test diet with BSFLM as the sole source of AA. All diets had 0.5% titanium dioxide (TiO 2 ) as an indigestible marker and the ratio of cornstarch to sucrose and soy oil in the test diet was identical to NFD to calculate AMEn by difference method. Birds were given feed and water ad libitum. Excreta samples were collected on days 17–20 and ileal digesta on day 21. The SID of lysine, methionine, cysteine, threonine, isoleucine, and valine was 86.3%, 88.7%, 72.8%, 85.5%, 89.6%, and 88.6%, respectively. Apparent retention of gross energy in BSFLM was 64.5% ± 2.27% and AMEn was 2902 ± 101 kcal kg −1 dry matter. The data will aid in accurate incorporation of BSFLM in poultry feeding programs.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
