Hazards associated with different variables of allo‐grooming

Hazards	Variable	Analysis (a)	Effect	Reference
Higher feed bunk availability (0.6 m/cow vs. 0.3 m/cow)	Social licking (s/day), at the feeding place	UA	↑	Val‐Laillet et al. (2009)
	Social licking (s/day), in the alley	UA	↑
	Social licking (bouts/day), at the feeding place	UA	ns
	Social licking (bouts/day), in the alley	UA	ns

↑/↓ = significant increase/decrease (p < 0.05); ns = not significant. The colour of the sign (red or green) indicates whether the effect is considered positive from an animal welfare perspective (green) or negative (red).

^(a)UA = univariable, MA = multivariable.
