An integrated approach for the enhancement of reproductive performance of white rhinoceroses (Cerathotherium simum) in the EEP

Abstract
The goal of this IRF-SOS Rhino funded multi-disciplinary,
multi-institutional research is to work on possible solutions to overcome the reproductive problems occurring in the captive white rhinoceros population. problems include 1) acyclicity; 2) variable estrous cycle lengths of 35 or 70 days; 3) mating failure due to acyclicity, or silent estrus due to sibling relationship/mate choice problems; 4) ovarian and uterine pathologies; 5) male sub- and infertility. Our combined approach to overcome these problems includes: 1) endocrine monitoring; 2) transfer of animals to enhance natural breeding; 3) clinical examinations of reproductive soundness in male and female white rhinos; 4) development of artificial insemination (AI); 5) development of treatment protocols for uterine and ovarian cystic conditions; 6) attempts of manual semen collection in unsedated male white rhinoceroses. Further focus is being placed on the ultrasonographic examination of the captive Northern white rhinoceroses, which belong to the most endangered species of large mammals worldwide.
