Carcinosarcoma in a White Rhinoceros (Ceratotherium simum simum)
In Rhinocerotidae, there are very few reports of tumors and no reports of a mixed tumor. This paper reports the case of a male 33-year-old southern white rhinoceros. Grossly, there were two masses in the coelomic cavity and solid nodules in the liver. Histologically, all tumors had a biphasic pattern that consisted of malignant epithelial cells (cytokeratin- and E-cadherin-positive) and non-epi...
متن کاملMilk composition of a free-ranging white rhinoceros (Ceratotherium simum) during late lactation
The study of the detailed composition of milk is mainly limited to the few commercially exploited animals such as the cow (Bos taurus), sheep (Ovis aries), goat (Capra hircus), camel (Camelus bactrianus), water buffalo (Buabalus bubalis) and yak (Bos grunniens) (Jennes and Patton 1976; Oftedal 1984; Park and Haenlein 2004). For most other animals, the information is limited to the content of th...
متن کاملProfiling patterns of fecal 20-oxopregnane concentrations during ovarian cycles in free-ranging southern white rhinoceros (Ceratotherium simum simum).
Unlike their wild counterparts, many white rhinoceros females in captivity fail to reproduce successfully such that current captive populations are not self-sustaining. The causes of the problem are poorly understood. Variation in cycle length and long periods of acyclicity are characteristics of the majority of these non-reproducing females in captivity but it is unknown whether these characte...
