Feeding and related social behaviour during limited browse in a herd of captive elands (Taurotragus oryx) - expariment with tree like branch holder.
 LIŠKOVÁ, Markéta
The thesis is focused on the analysis of feeding, comfort and social behavior in a herd of farmed eland (Taurotragus oryx) initiated by the presentation of browse to the tree stand. In 2008 and 2010 were obtained 15-hour video behavior gradually with three different adult males of elands at Czech University of Life Sciences farm at Lány. The aim of this work was to evaluate the accessibility of a limited food source (browse), the frequency of feeding behavior in relation to a rank in the herd, age and sex and find out if the stand can be also used as a enrichment to increase proportion of comfort behavior (scratching, grooming). Adult male in the herd has always been high ranking and no one attacked him, followed by females and juveniles. Access to a limited browse was influenced by the level of aggression of adult female towards the younger and lower ranking ones, these females attacked with the same frequency also the youngs. The dominant male attacked especially the dominant females. The length and frequency of all types of behavior were related to a sex of the individual, the rank and the presence of a calf. With higher rank individuals had longer access to a browse, display longer comfort behavior than lower ranking ones. We can conclude that both types of behavior performed more often males than females. Length and frequency of interactions with browse was supported during absence of calf in vicinity of stand.
