Abstract
In experiment 1, five diets formulated from wheat and four hulless barley (Silky, Falcon, Gainer and Dawn) cultivars were fed to two strains of hens (Hyline W36 and Dekalb Sigma) to measure production performance. Results showed that the hulless barley cultivars Silky, Gainer and Dawn can effectively replace wheat without any loss of egg mass, while all four hulless barley cultivars can replace wheat without any effect on feed efficiency or feed intake. In experiment 2, each of the diets in trial one, were formulated either with or without an exogenous enzyme cocktail and fed to Shaver White laying hens. Results showed that enzyme supplementation resulted in significant improvements (P < 0.05) in egg mass and feed efficiency, and small insignificant increases in egg production and egg weight over hens fed the unsupplemented diets. For experiment 3, the dietary levels of some major nutrients (P, lysine and methionine) were lowered by up to 10% in the presence of appropriate exogenous enzymes and fed to laying hens. The results showed that, compared to a regular diet (without exogenous enzymes) feeding reduced levels of P, lysine and methionine in the presence of exogenous enzymes, did not result in any significant reduction (P > 0.05) in egg production, egg mass and feed efficiency.

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
