You’ve got a friend in me: Exploration of personality concepts and validation of common personality tests in dairy cattle
Bibliographic record
Abstract
Dairy cows play a crucial role in Canada's agricultural sector, with large herd sizes driving high milk production and requiring efficient management strategies.Intensive housing systems optimize productivity but limit natural behaviours, raising welfare concerns.Social enrichment, particularly relevant for these highly gregarious animals, has been proposed to enhance well-being by promoting affiliative behaviours and reducing stress.However, the effectiveness of enrichment may vary among individuals, as cows display consistent behavioural patterns across time and contexts-referred to as personality-which shape their responses to enrichment.Despite growing interest in animal personality, research on dairy cattle remains limited, leaving the relationship between personality and enrichment largely unexplored.The scoping review synthesized existing literature on dairy cattle personality and its influence on responses to social enrichment, where 34 articles were included following PRISMA guidelines.In personality research, traits refer to consistent individual tendencies inferred from observable behaviour, while dimensions represent broader personality constructs formed by grouping related traits.The initial findings indicated that the reviewed articles failed to establish a clear framework linking behaviours to personality traits and organizing them into personality dimensions, overlooking the interdependence and contextual variability of traits.To address this, frameworks were developed based on the relationships identified in the articles, aiming to explore potential links between personality and behaviour.However, due to the limited number of long-term studies, the absence of short-term consistency assessments, and a narrow focus on isolated traits rather than broader personality dimensions, the findings may not be fully valid or reliable for personality identification.Behavioural patterns were rarely measured repeatedly or across varied contexts-both of which are essential for establishing stable personality traits.To further investigate this gap, an experimental study was conducted involving dairy cows, designed to assess the reliability and validity of behavioural tests commonly used to measure animal personality.Five behavioural tests-the Human Approach Test, Sudden Test, Novel Object Test, Open Field Test, and Novel Surface Test-were selected for validation in this animal trial.Their short-and mid-term consistency was assessed across three time periods, with comparisons made to identify consistent behavioural expressions across different contexts.Cows' behavioural reactions to test stimuli were recorded.Our findings suggest that the Sudden Test may be a reliable tool for measuring personality traits, as it demonstrated consistent individual behaviours

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.
