Abstract
Two studies were conducted to evaluate the effect of preslaughter electrolyte supplementation on weight loss, hydration, and beef quality of cull dairy cows. Cows were withheld from feed before slaughter for 36 or 24 h, and ambient temperature ranged from 22 to 32°C or from 12 to 17°C for Exp. 1 and 2, respectively. In Exp. 1, cull dairy cows (n = 60) were given the control treatment (CON; n = 30) or the on-farm electrolyte supplementation treatment (PRE; n = 30). Cows on the PRE treatment tended to have a greater (P = 0.06) decrease in packed cell volume than did CON cows throughout the preslaughter period. Longissimus samples from PRE cows exhibited greater drip loss (P = 0.04) and tended (P = 0.06) to have a lower 24-h pH than did samples from CON cows. In Exp. 2, cull dairy cows (n = 46) were given the CON (n = 16), PRE (n = 16), or posttransportation electrolyte supplementation treatment (n = 14). Cows on the PRE treatment tended to have a lower (P = 0.06) percentage of weight loss during transport than did untreated cows. Results from both experiments demonstrated the potential for preslaughter electrolyte supplementation to attenuate the negative effects of stressors on cull dairy cows, but supplementation appears to be more effective during periods of hot weather and extended feed withdrawal.

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
