Effects of Treatment of Sorghum Stover Residue With Ammonium Hydroxide on Cell Wall Composition and in vitro Digestibility
Bibliographic record
Abstract
The study was undertaken to determine the effects of ammonium hydroxide (NH4OH) treatment of sorghum stover residue on composition and in vitro dry matter disappearance (IVDMD) of two sorghum varieties, Dale (tall, sweet sorghum variety) and Brown mid rib (BMR) (Short, grain sorghum variety). The residue was treated with; water only (T00), 50 g NH4OH kg-1 residue dry matter (DM) (T50), 100 g NH4OH kg-1 DM (T100), and untreated control (neither water nor NH4OH) (TUN) and allowed to react for one week before chemical analysis was performed. The fiber content (ADF and NDF) were not affected by the levels of alkali treatment but the crude protein (CP) and Soluble protein contents were both increased by alkali treatment. There was an increase (P < 0.05) in dry matter digestibility in vitro (IVDMD) by NH4OH treatment from 529 g kg-1 to 651 g kg-1 in T50 and T100. The improvement in IVDMD may indicate that NH4OH helps disrupt the lignin–carbohydrate complexes. The development of more economical and safe procedures which improve digestibility of the structural cell wall components would be very beneficial for improving the use of crop residue as feedstock for livestock and bioethanol production.

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.
