Comparative investigations on digestion in grazing (Ceratotherium simum) and browsing (Diceros bicornis) rhinoceroses
Rhinoceroses represent the largest extant herbivores with extensive dietary specialization for plant groups like browse (black rhino Diceros bicornis) or grass (white rhino Ceratotherium simum). However, it is not clear to what extent such diet selection patterns are reflected in adaptations of digestive physiology of the respective feeding types. In this study, feeding trials with […]
Faecal corticosterone responses of black rhinos (Diceros bicornis) to a transfer between housing facilities within a zoo
Faecal corticosterone metabolites (FCM) of four black rhinos (Diceros bicornis) at Magdeburg Zoo in Germany were investigated to assess the stress level associated with an internal transfer of rhinos between housing facilities. Moving rhinos within the zoo led to a punctual increase of FCM concentrations in three animals. We observed no signs of a period […]
