Sperm motilities were high in these rhinoceroses. These samples had very little accessory gland fluids in them and therefore were probably not representative of a normal ejaculate. Sperm abnormalities were high in these species. White and Indian rhinoceroses exhibited primarily sperm tail abno... |

Chutes used for restraint in sperm collection. Equipment manipulations and personnel protection is facilitated by restraining rhinoceroses in chutes. During procedures at zoos, observations were made on the effectiveness of current chute systems in restraining rhinoceroses.
Chutes should be... |

Ejaculate volumes are high in rhinoceroses. The low volumes in white rhinoceroses have resulted from incomplete ejaculation in these animals. The highest sperm counts were from an Indian rhinoceros, but these values resulted from sperm-rich samples resulting from the ejaculation of a highly con... |

These are usually latex coverings filled with warm water. They provide warmth and pressure stimulation to the penis. AVs have been minimally successful in collection of semen from rhinoceroses. Lack of sustained erections in the rhinoceros has made placement of AVs difficult. Furthermore, use... |

Semen has been cryopreserved from Rhinoceros unicornis, Ceratotherium simum, Diceros bicornis. Both pellet and straw cryopreservation methods have been used in the rhinoceros.
Poor recovery of rhinoceros sperm from freezing is indicated by low postthaw motilities (20-70%). Some improvement in ... |

Rhinoceroses have been anesthetized for electroejaculation but only limited attempts can be made without risk to the animal. Multiple samples can be obtained with minimum or no risk to the animal by semen collection from unanesthetized rhinoceroses. |

It has been successfully applied to the rhinoceros. Direct massage of the penis begins with slow stroking that proceeds to vigorous massaging by the operator until the rhinoceros ejaculates. Rhinoceroses are the most receptive to this procedure and therefore it has been the method most frequent... |

Rectal massage in the rhinoceros involves massaging the accessory glands just inside the anus. Rectal massage alone was also ineffective in producing seminal fluids from the rhinoceroses of this report. However, when rectal massage was followed with penile massage, seminal fluids were acquired... |

Rhinoceroses have been anesthesized for electroejaculation, but unanesthetized rhinoceroses have been successfully electroejaculated with both rectal probe and hand-held ring electrodes. As with rectal massage, this stimulation produced seminal emission into the posterior urethra. Semen was the... |
