title: Gross and microscopic observations of ovarian abnormalities from five Burchell's zebra, Equus Burchelli antiquorum, Smith 1841.
abstract: Five pair of zebra ovaries were submitted to the Onderstepoort Veterinary Research Institute for examination because of unusual uni- and/or bilateral gross appearances. Microscopic findings revealed an accessory spleen encapsulated by the ovarian peritoneum, a case of tubo-ovarian cysts, one example of ovarian aplasia, an example of germinal inclusion cysts and an abnormal follicular haemorrhage related to pressure necrosis of a nearby corpus luteum. Similarities to the ovary of the domestic mare were also seen and some are briefly described.
