Maintenance of captive black rhinoceros (Diceros bicornis) on indigenous browse in Zimbabwe: nutrition and energetics

Poor nutrition has been implicated as a key factor contributing to the high levals of morbidity and mortality seen in captive populations of black rhinoceros, Diceros bicornis (Kock et al, 1992; Miller, 1993). The translocation of four adult black rhinos (2 males, 2 females) to the Intensive Management Center at Sinamatella, Hwange National Park, Zimbabwe, in January 1995 led to the question of how best to maintain these endangered animals whilst held captive in situ. Given that diets of cut browse are desirable, the study aimed to determine whether these animals could be maintained on diets of indigenous cut browse. In doing so, it would also provide a protocol for maintaining captive black rhinos on indigenous browse.
