↑/↓ = significantly higher/lower (p < 0.05). The colour of the sign (red or green) indicates whether the effect is considered positive from an animal welfare perspective (green) or negative (red). Arrows in black reflect an unclear interpretation of the effect from a welfare perspective.
Statistical analysis: MA = multivariable analysis (in the case of univariable preselection of factors, only effects of the final models were considered).
OLA = outdoor loafing area (5, 8, 12, 15 m2/cow).
Percentage of successful head butts increased with an increase in space allowance up to 12 m2/cow in the OLA, but decreased with 15 m2.
Stocking density expressed in cows/cubicle (e.g. 150% means 1.5 cow/cubicle).
