Abstract
1. A 4 x 2 factorial arrangement of treatments was used to investigate the effect of graded levels of sunflower meal (SFM; 0, 70, 140 and 210 g/kg) and enzyme supplementation on gut morphology, nutrient utilisation and growth performance of young turkeys from 0 to 8 weeks of age. The enzyme supplement used in the study contained non-starch polysaccharide (NSP)-degrading activities and supplied 500 U pectinase, 40 U cellulase, 1600 U xylanase, 800 U glucanase, 200 U mannanase, 20 U galactanase per kg diet. 2. The use of SFM resulted in an increase in the height and width of intestinal villi, and a linear decrease in crypt depth. Dry matter digestibility and energy metabolisability decreased in groups fed diets with a moderate (140 g/kg) and high (210 g/kg) SFM content. 3. A decrease in dry matter digestibility and energy metabolisability was most likely the reason for a reduction in body weights of 8-week-old turkeys fed on diets containing 140 g/kg (from 4 x 17 to 4 x 01 kg) and 210 g/kg (from 4 x 17 to 3 x 93?kg) of SFM. 4. The addition of enzyme resulted in a slight increase in villus height, a significant increase in the number of goblet cells and an increase in digestibility coefficients for crude fat. 5. The results of this study demonstrate that turkey diets can be effectively supplemented with high-quality sunflower meal at a concentration of approximately 70 g/kg. It should be noted, however, that at 8 weeks of age the body weight of turkeys fed on diets containing 140 and 210 g/kg of SFM could be lower by 4 and 6%, respectively, than in those receiving the soyabean meal-based diets.

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
