Abstract
Abstract Beef cattle are major contributors of enteric methane ( CH 4 ) emissions in Canada. Feeding forages containing condensed tannins ( CT ) has been suggested as a means of reducing enteric CH 4 emissions and improving production efficiency. Sainfoin ( O nobrychis viciifolia ) is one of the CT ‐containing legumes, which has also been recognized to have several additional beneficial properties. This study compared sainfoin silage ( SS ) and lucerne ( M edicago sativa ) silage ( LS ) with respect to animal performance, enteric CH 4 production, abundance of selected rumen microbes and selected serum parameters in yearling steers during a Canadian winter. Sainfoin silage in our study contained approximately 12 g CT kg −1 dry matter ( DM ), a level which did not adversely affect silage palatability as steers fed SS experienced higher DM intake. However, animals fed LS and SS had similar body weight gain over the course of the trial. Feeding SS resulted in lower blood urea nitrogen concentrations and relative abundance of methanogenic archaea in rumen fluid. Yet, microbial population shifts fell short of exerting significant influence on enteric CH 4 emissions. This study suggests that under western C anadian growing and animal‐rearing conditions, sainfoin is not yet competitive with lucerne forage with respect to enteric CH 4 emissions or animal productivity warranting further research and development.

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
