Abstract

fetched live from OpenAlex

The effects of delivery time (0900 or 2100) of a diet consisting of 45% of dry matter as chopped hay and 55% of dry matter as concentrates on milk production of dairy cows were determined in a 6-wk experiment consisting of 3 wk of adaptation and 3 wk of sampling. Feed delivery time did not affect feed intake and milk production. Average milk fat percentage decreased from 2.14% during week 4 to 1.73% during week 6. The low milk fat could was assumed to be caused by the short dietary particle lengths, and could have prohibited effects of feeding time on milk production. The decrease in milk fat over time might have been due to increased sorting against long and medium length feed particles. This increase in sorting was greater in 0900-fed cows than in 2100-fed cows. Key words: Time of feeding, dairy cows, milk production, sorting

Not 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.
