Metabolizable energy and standardized ileal digestible amino acid contents of a high-protein sunflower meal fed to broiler chicks
Bibliographic record
Abstract
This study was conducted to determine the standardized ileal digestible amino acid (AA) and nitrogen-corrected apparent metabolizable energy (AMEn) contents of a high-protein sunflower meal (HiSFM) fed to broiler chicks. A total of 144 broiler chicks were randomly allotted to one of three dietary treatments with eight replicate cages of six birds. Birds were fed the experimental diets from day 14 to day 21 of age. The results showed that gross energy, crude protein, nonphytate phosphorus, lysine (Lys), methionine (Met), threonine (Thr), and total nonstarch polysaccharide contents of HiSFM were 4178 kcal kg−1, 48.7%, 0.86%, 1.59%, 0.75%, 1.45%, and 14.6%, as-fed basis, respectively. The standardized ileal digestible Lys, Met, and Thr of HiSFM were 12.6, 6.8, and 11.6 g kg−1 (dry matter basis), respectively. In addition, the AMEn content of HiSFM fed to broiler chicks was 1785 kcal kg−1. In conclusion, compared with literature values for sunflower meal, HiSFM had lower standardized ileal digestibility of indispensable AA and higher AMEn content. The standardized ileal digestible AA and AMEn values of HiSFM obtained from the current study could be used when formulating poultry diets and to obtain predictable bird performance.

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.
