Wild sheep are pronounced flock animals, shy, attentive and have quick flight reactions, while defending their offspring when necessary. Furthermore, they show strong antipredatory behaviour. In this study the differences in antipredatory behaviour among the following breeds, Old Norwegian, Spaelsheep, Norwegian fur sheep, Suffolk, Steigar, and Dala was experimented towards seven stimulus regimes. Tests were performed on 2-5 years old ewes with lambs inside standardized and fenced home pastures. The stimulus regimes were: man in rain poncho, trolley, ball on trolley (blind stimuli), stuffed wolverine on trolley, stuffed lynx on trolley, stuffed bear on trolley, and man in a rain poncho with a dog on leash (carnivore stimuli). Carnivore stimuli caused longer recovery times and longer flight distances than the blind stimuli which indicates that the sheep are able to distinguish between dangerous and less dangerous stimuli. In summary, the results of this study show that lighter sheep breeds display stronger antipredatory reactions than heavier breeds.
