Abstract

fetched live from OpenAlex

ABSTRACT A 2-yr study was conducted to determine the effects of supplementing wheat–corn blend dry distillers grains with solubles (DDGS) on beef cow performance and estimated DMI of barley crop residue. Each year, 25 ha of forage barley (cv. Ranger) was seeded and managed for weed control. In fall, the crop was swathed and combined to collect straw-chaff crop residue in 13-kg piles. The field was further subdivided into six 4-ha paddocks for grazing using portable electric fence. Forty-eight spring-calving Black Angus beef cows (BW = 598.2 ± 4.2 kg) were stratified by BW and days pregnant and randomly allocated to 1 of 3 supplement treatments (2 replicates): (1) 100% DDGS (70:30 wheat:corn blend; WCDDGS); (2) 50% WCDDGS plus 50% rolled barley grain (50:50); or (3) 100% rolled barley grain (control; BAR) while winter grazing barley strawchaff piles [TDN = 45.4, CP = 8.6 (% DM)]. Cows were allocated crop-residue piles on a 3-d basis. Cow BW, BCS, and rib and rump fat were measured at the start and end of the trial, and cow BW was corrected for conceptus gain based on calving data. Supplementation strategy did not influence (P > 0.1) forage intake. Supplementation of 100% WCDDGS or a 50:50 blend of WCDDGS and barley grain resulted in greater (P

Teacher imitation

Not 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.
