Effects of Feeding Locally Grown Whole Barley With or Without Enzyme Addition and Whole Wheat on Broiler Performance and Carcass Traits
Bibliographic record
Abstract
Two experiments were conducted to investigate the impact of increasing dietary levels of whole barley (WB) with or without exogenous enzymes and of whole wheat (WW) without E fed from 7 d of age, on performance and carcass characteristics of broilers. Experiment 1 was conducted with corn-soybean meal grower diets containing WB at 0, 10, 10 + enzymes, 15, or 15% + enzymes. The finisher diets contained, as fed, WB at 0, 15, 20 + enzymes, 15, or 20% + enzymes. In Experiment 2, grower diets contained 0, 10, 10, 20, or 20% WW with 0, 20, 35, 20, or 35% WW in the finisher diets. No enzymes were used for WW diets. In each Experiment, 1,500 1-d-old Ross x Ross male broilers were randomly distributed in 30 floor pens of 50 birds each. Six replicates were allotted to each treatment. Body weight, average daily gain (ADG), feed intake (FI), and feed efficiency ratio (FER) were measured at 7, 21, and at 38 d of age. In Experiment 1, ADG was lower (P < 0.05) in the control vs. Diet 5. However, FER with enzyme addition was lower, and FI with enzymes was higher (P < 0.05). Final BW, gizzard, and pancreas weights were higher (P < 0.05) with WB inclusion. In Experiment 2, ADG and BW significantly increased with addition of WW, although the response was best for Diets 2 and 3. Abdominal fat and carcass weights increased (P < 0.05) with the WW levels in the diets.

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.
