Mammary mTOR activity during intravenous glucose infusions into lactating dairy cows
Bibliographic record
Abstract
The effects of glucose on milk protein yield and mammary mTOR activity were studied in eight multiparous early lactation Holstein cows fed a TMR with 40% NDF content. Treatments were jugular infusions of either physiological saline (SAL) or approximately 900 g/d glucose (GLC) in a cross over design for two 6 d periods during which blood, milk and mammary tissue were sampled. GLC infusion increased plasma insulin but did not significantly increase plasma glucose and only tended to increase milk protein yields. NEAA and BCAA plasma concentrations significantly increased and decreased, respectively, with GLC treatments. Furthermore, reduction of the phosphorylation state of mTOR signalling protein 4EBP1, as well as reduction of total and phosphorylated S6K1 abundances resulted from the infusion of GLC. The expected increase in milk protein synthesis due to glucose infusion was not observed, presumably because protein synthesis was stimulated in muscle tissue rather than the mammary glands.

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.
