Effect of urea supplementation on urea kinetics andsplanchnic flux of amino acids in dairy cows
Bibliographic record
Abstract
Five lactating dairy cows were used in a cross-over design to determine if increased hepatic ureagenesis affected hepatic removal of amino acids (AA).Hepatic ureagenesis accounted for all urea entry rate (measured with a 3-d infusion of 15 N 15 N-urea) and both increased with urea supplementation.Neither liver removal of essential AA or milk protein yield was affected by urea supplementation.Gut entry rate and its partition between anabolic and catabolic fates were also unaltered by treatment.Saliva contributed to 0.31 to 0.50 of urea gut entry rate.In cows producing 32 kg/d of milk and fed a diet supplying 157 g CP / kg DM, increased hepatic ureagenesis did not result in decreased post-liver supply of essential AA and subsequent milk protein yield.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
