The inter‐relationship between processing‐induced molecular structure features and metabolic and digestive characteristics in hulled and hulless barley (<i>Hordeum vulgare</i>) grains with altered carbohydrate traits
Bibliographic record
Abstract
BACKGROUND: The present study aimed to determine the microwave irradiation (MIR)-induced changes in protein molecular structures in barley (Hordeum vulgare) grains in relation to the truly absorbable protein nutrient supply to ruminant livestock systems. Samples from hulled and hulless cultivars of barley, harvested in consecutive years from four replicate plots, were evaluated. The samples were either kept raw or were irradiated with microwaves for 3 min (MIR3) or 5 min (MIR5). The truly absorbable protein nutrient supply to ruminant livestock systems was evaluated using the DVE/OEB system (DVE, truly absorbed protein in the small intestine; OEB, degraded protein balance). Molecular structure changes as a result of processing were revealed by vibrational molecular spectroscopy in the mid-infrared electromagnetic radiation region. RESULTS: Compared to the raw samples, MIR processing decreased (P < 0.05) the truly absorbable microbial crude protein and increased (P < 0.05) the truly absorbable rumen undegraded protein and endogenous protein supply without affecting the total truly absorbed protein supply to the small intestine (DVE) and degraded protein balance (OEB) in ruminant livestock systems. Changes in protein molecular structure (spectral intensities) were highly correlated with the changes in the truly absorbed protein nutrient supply to ruminant livestock systems. CONCLUSION: The results of the present study show that the changes in protein molecular structure as a result of MIR feed processing were associated with the truly absorbed protein supply to ruminant livestock systems. © 2016 Society of Chemical Industry.

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.
