A first time for everything: The influence of parity on the behavior of transition dairy cows
Bibliographic record
Abstract
Over the last 20 years an increasing amount of research has described how dairy cow behavior changes during the few weeks before and after parturition, also known as the transition period. Dairy cows experience several challenges during this period, including pain associated with pregnancy and labor, social stressors associated with pen moves, changes in diet, and navigating new routines that include daily milking in a parlor or automatic milking system. For cows calving for the first time ("primiparous"), these experiences may be particularly challenging compared with those animals who have calved previously ("multiparous"). The objectives of this review are to (1) summarize the research to date on behavioral differences between primiparous and multiparous animals during the transition period, (2) describe the effect of management practices, such as regrouping and milking, on primiparous animals, and (3) suggest management recommendations and future directions for research focused on the behavior of primiparous cows.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
