    Hybridization of wildlife species, even in the absence of introgression, is of concern due to wasted reproductive effort and a reduction in productivity. In this study we detail an accidental mating between a female nyala ...
  • Hartman, Marthinus Jacobus; Kirberger, Robert M.; Tordiffe, A.S.W. (Adrian Stephen Wolferstan); Boy, Sonja Catharina; Schoeman, Johan P. (BMJ Publishing Group, 2015-02)
    This case presents a thorn-induced abdominal foreign body granuloma that was removed with single incision laparoscopic surgery and an extraction bag. An 11-yearold female cheetah presented for routine laparoscopic ovariectomy. ...

    Enzyme immunoassays (EIA) that measure faecal testosterone metabolites (fTM) are useful tools to monitor gonadal activity. The aim of this study was to validate an “in-house” epiandrosterone EIA to monitor fTM in spotted ...
