Use of Prevotella bryantii 25A as a Probiotic to Reduce the Risk of Ruminal Acidosis in Dairy Cows
Bibliographic record
Abstract
This study was conducted to determine if adding relatively large quantities of a rapid growing, starch fermenting rumen bacterium, Prevotella bryanti, strain 25A, to the rumen of dairy cows would modulate rumen fermentation to reduce the risk of sub-acute ruminal acidosis (SARA). Twelve rumen fistulated dairy cows were fed an energy dense barley diet during a 3 week pre-partum period and then for 7 weeks post partum. Cells of P. bryantii that had been grown in a 100 liter fermenter were stored as frozen cells and then added daily to the rumen of six of the cows. Cows receiving the inoculum had lower post-feeding ruminal lactic acid, higher ruminal acetate and butyrate, and higher production of milk fat. However, since neither experimental nor control cows developed signs of SARA under the feeding conditions of this experiment, conclusions about protection against SARA by P. bryantii can not be reached.

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.
