Effect of enzyme supplementation on theperformance of broilers fed maize, wheat, barley ormicronized dehulled barley diets
Bibliographic record
Abstract
The effects of an enzyme preparation on the performance and carcass characteristics of broilers fed diets based on maize, wheat, hulled barley (Bedford) or micronized dehulled barley (MDB) {Bedford) diets were evaluated. A commercial enzyme containing (3-glucanase and xylanase was used. One thousand and nine hundred-twenty one-day-old broiler were used for this study. The broilers fed the MDB diets had a lower average daily gain (ADG) (PO.05) and lower average daily feed intake (ADFI) (PO.05) than the broilers fed the other diets. There was a significant period x grain interaction (PO.05) for ADG with the broilers on the barley diets performing better in the grower phase. The broilers received enzymes showed an enzyme x period interaction with the feed conversion rate (FCR) of those birds in the starter phase doing better (PO.05) than in the grower phase compared to those fed the unsupplemented diets. The birds fed MDB diets had higher digesta viscosity than birds fed unprocessed barley, maize or wheat diets (PO.01). Feed enzyme addition to the MDB diet caused a decrease (PO.01) in the digesta viscosity by 49% and an improvement (PO.05) feed conversion ratio (FCR) both for the starter and the grower phase.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
