Cows do show consistency over time in behaviours during milking and in total performance of abnormal behaviours in home pen. Behaviour reactions when exposed to novel object were moderately stable over time. However, consistency in behaviours differed between the breeds, where Holstein cows were consistent in more behaviours than SRB. Even if cows showed consistency also in milk production traits, the results of my study showed limited relationship between personality and production. More theoritcal and empirical work is therefore needed to fully understand this predicted relationship.
