Extract

Captive Przewalski horses are generally kept as harem bands consisting of several females with their offspring and one stallion (Tilson et al., 1988). These husbandry procedures together with an approximately equal sex ratio at birth, led to an abundance of surplus males (Boyd and Houpt, 1994). In 1986 the European Breeding Programme recommended the establishment of bachelor groups to manage the surplus males in a cost-effective way (Kolter and Zimmermann, 2001). There have been reports of severe and sometimes fatal aggression between stallions during or immediately after their introduction to established bachelor groups (Kolter and Zimmermann, 2001). The main objectives of this study were to investigate the changes in behaviour during and immediately after introduction of Przewalski horses to bachelor groups, taking into account the effects of other factors such as age. The results are discussed in relation to enclosure type, animal husbandry and the social behaviour of equids.
