Abstract
Abstract This study was conducted to determine the effects of dietary probiotic supplementation on the ileal digestibilities of nutrients and growth performance in broilers. Two thousand, eight hundred and eighty male broiler chickens at 1 day of age were randomly allotted to eight treatment groups and fed for 6 weeks the maize–soybean meal‐based diets containing 0, 0.2, 0.4 or 0.6% AgiPro A100® (a probiotic) and 0 or 6 ppm flavomycin (an antibiotic). This well‐established antibiotic was used as a positive control for the efficacy of AgiPro A100®. Dietary supplementation with either the probiotic or the antibiotic alone did not affect ( P > 0.05) feed intake or average daily gain (ADG) of broilers between days 1 and 42 of life. However, there was a significant antibiotic × probiotic interaction effect ( P < 0.05) in increasing ADG during the entire experimental period. Notably, dietary supplementation with the probiotic or the antibiotic consistently improved ( P < 0.05) the ileal digestibilities of crude protein and most amino acids in 21‐ and 42‐day‐old chickens. Supplementing the probiotic to broiler diets also improved ( P < 0.05) the ileal digestibilities of dry matter, energy, calcium and phosphate in the birds. Collectively, these results indicated that AgiPro A100® is an effective alternative to flavomycin in chicken production. Copyright © 2007 Society of Chemical Industry

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
