Assessment of ABMs for restriction of movement (social behaviour) in terms of feasibility, sensitivity and specificity

ABM	Description of the ABM
Agonistic interactions	Definition: Number of agonistic interactions (head butts without displacement, displacement, chasing, fighting, chasing up from the lying area) per cow and hour (Welfare Quality®, 2009). A high number of agonistic interactions is indicative of a high level of group stress. Feasibility: Low ‐ assessment is time‐consuming and requiring training. Sensitivity and Specificity: Low sensitivity and low specificity (human‐animal relationship can also influence it).
