SRB cows were consistent over time in duration of interactions with novel object but in no other behaviours recorded when socially separated and exposed to novel object (Table 4). Holstein cows were consistent in latency to approach novel object (Table 4), time spent less than 2 meters from novel object (Table 4) but not in duration of interactions with novel object (Table 4). Holstein cows were also consistent in time spent in upright position with head turned in direction to heard but not in frequency of vocalisations when socially separated and exposed to novel object (Table 4).
