| Schwarzenberger et al. have already shown that black rhinos probably have a post partum oestrus. Mating, however, is not allowed until about 15 months or more later. Manipulation of the post partum period by means of management can perhaps reduce the intercalving period and so increase the repr... |

This is often f... |

They do not tolerate calves close to themselves and calves are continuously in danger of being killed in such cases. Apparently white rhinos need a certain mini... |
