Diet, total plasma homocysteine concentrations and mortality rates in broiler chickens
Bibliographic record
Abstract
The aim of this study was to determine if total plasma homocysteine (HCY) concentrations and mortality rates due to ascites syndrome and (AS) sudden death syndrome (SDS) in broiler chickens could be lowered by diet. Elevated plasma HCY is an independent risk factor for cardiovascular disease in humans. A total of 828 day-old male broiler chickens (Arbor Acre) were fed, for 6 wk, either a basal practical diet or one supplemented with excess vitamins B6 and B12, folic acid and betaine to stimulate the degradation of HCY. The supplemented diet decreased plasma HCY by 17% (P < 0.05; n = 16 per diet). Total mortality due to AS and SDS was 18% lower in the supplemented diet but this difference was not statistically significant. Key words: Homocysteine, folate, chickens, cardiovascular disease, ascites, sudden death syndrome

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.
