Effect of grain type and dried distillers grains plus solubles oil concentration on site of digestion in cattle fed finishing diets
Bibliographic record
Abstract
The objective of this experiment was to determine the effects of grain type (rolled corn vs. rolled barley) and oil concentration of dried corn distillers grains plus solubles (DDGS; moderate = 7.9% vs. low = 4.5% ether extract) on site of digestion. Seven ruminally and duodenally cannulated Holstein steers (716 ± 8.9 kg) were used in a 4 × 7 Youden square with experimental periods of 24 d. True ruminal organic matter (OM) and crude protein (CP) digestibility (% of intake) as well as intestinal (% of entering duodenum) and total tract starch digestibility was greater (P ≤ 0.03) in steers fed diets containing barley than in steers fed diets containing corn. Ruminal disappearance and ruminal, intestinal, and total tract OM, CP, and starch digestibility were not influenced (P ≥ 0.11) by feeding diets containing DDGS with differing oil concentration. Total tract lipid digestibility (%) was greater (P < 0.001) in steers fed diets containing moderate-oil DDGS than low-oil DDGS. These data indicate that including a low-oil DDGS, as compared with a moderate-oil DDGS, in finishing diets containing rolled corn or rolled barley does not influence intake or site of digestion of nonlipid components.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
