Effect of Tween 80 and salinomycin on ruminal fermentation and nutrient digestion in steers fed a diet containing 70% barley
Bibliographic record
Abstract
Ten Jersey steers (484 ± 55 kg) were fed a basal diet of 70% rolled barley grain and 30% alfalfa silage [dry matter (DM) basis] with or without additives, in a replicated 5 × 5 Latin square experiment. Treatments (additives per kilogram dietary DM) were: C, no additives (control); T, Tween 80 (2 g kg −1 ); SH, salinomycin (13 mg kg −1 ); TSM, Tween 80 (2 g kg −1 ) plus salinomycin (6.5 mg kg −1 ); and TSL, Tween 80 (2 g kg −1 ) plus salinomycin (3.25 mg kg −1 ). Ruminal pH, concentrations of ammonia, total free amino acids, reducing sugars and total volatile fatty acids (VFA), and fluid phase viscosity were unaffected (P > 0.05) by treatment. Ruminal carboxymethylcellulase, xylanase and amylase activities, numbers of protozoa, and outflow rates of the liquid and solid phases of ruminal contents did not differ (P > 0.05) among treatments. Ruminal lactic acid bacteria populations tended (P < 0.1) to be smaller with SH compared with C, but counts were unaffected (P > 0.05) by T, TSL and TSM. Partitioning of ruminal digesta and microbial protein flow were similar (P > 0.05) among treatments. Compared with C, the ruminal rate of degradation (in situ) of alfalfa DM tended to be higher (P < 0.10) with SH, and the rate of barley grain DM degradation was higher (P < 0.05) with T. Intake and apparent digestibilities of DM, neutral detergent fibre (NDF), acid detergent fibre (ADF) and crude protein were unaffected (P > 0.05) by treatment, as were blood glucose and urea levels. Tween 80 and salinomycin did not affect ruminal fermentation or nutrient digestibility in steers fed a barley grain/alfalfa silage diet. Key words: Tween 80, salinomycin, ruminal fermentation, digestibility, steer

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
