Abstract

Flow cytometric sexing of spermatozoa followed by application in artificial insemination or in vitro fertilization provides a unique opportunity to predetermine the sex of offspring and might enhance the conservation management of endangered species in captivity such as the elephant and rhinoceros. To obtain an indication of the sortability of spermatozoa from these species, the relative DNA differences between X and Y chromosome bearing spermatozoa (fresh, frozen thawed, epididymal) from three rhinoceros species [white (Ceratotherium simum), black (Diceros bicornis), Indian (Rhinoceros unicornis)] and both elephant species, the Asian and the African elephant (Elephas maximus, Loxodonta Afri..
