Abstract

fetched live from OpenAlex

The objective of the current research was to examine the association of\nherd level disease incidence with the return over feed (ROF) (milk income\nminus feed cost) herd profit index offered through Canwest Dairy\nHerd Improvement. The lactational incidence risks (LIR) for displaced\nabomasum, retained placenta, clinical mastitis, milk fever, clinical ketosis, and\nlameness submitted by producers (n = 48) were similar to previous reports. However, there was no\nnegative association of clinical disease LIR’s with ROF. Subclinical\nketosis and subclinical mastitis cumulative incidence were determined\nduring the early postpartum period by using a cow-side test for\nbetahydroxybutyrate in milk and the California Mastitis Test, respectively. Subclinical\nmastitis was not associated with ROF. However, a unit\nincrease in the cumulative incidence of subclinical ketosis was associated\nwith a decrease of $0.015/cow/day in the ROF. The results\nhighlight the economic significance that subclinical ketosis may have\nin Ontario dairy herds.

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.

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.
