Abstract [en]

Research where personality in animals is studied is becoming more and more common. In this area there are different concepts like behavioural syndrome and animal personality and they usually talk about consistency in behaviour over time and situations. This consistent individual behaviour can be used as an indicator of how individuals can handle and adjust to new situations in the environment. Because of this, personality studies in animals are very important in animal welfare. In this study personality in dairy cattle in lose housing were studied. 28 cows of the breeds Swedish black and white cattle (SLB) and Swedish red and white cattle (SRB) was studied during three observation situations (milking, undisturbed behaviour and novel object). With the help of Principal component analysis four components that together explained 72% of the variation in data were found. The two first components could then be interpreted. The first component corresponds to the dimension extraversion in the”Big five” model that is used in personality studies in humans. The second component was the opposite of the first one, which means that it showed low activity and low sociability. This low activity could indicate fear dependent on why the cows were standing so much. T-tests only showed significant differences in the behaviour based on the age of the cows, which indicates that the personality trait becomes more typical with higher age. The conclusion is that there are individual differences in dairy cattle which could be interpreted as personality traits.
