With a history of verified results from collaborative research, CREW scientists understand the importance of developing
scientific capacity within individuals and organizations throughout North America to overcome the serious loss of
genetic diversity facing captive African and Asian rhino populations.
In the first year of a three-year National Leadership Grant from the Institute of Museum and Library Services (IMLS), CREW
has begun building a Rhino Assisted Reproduction Enterprise (RARE) in collaboration with SeaWorld Busch Gardens Reproductive Research Center and several other zoos accredited by the Association of Zoos & Aquariums. These zoos contribute the veterinary and rhino keeper staff time needed to learn and implement rhino assisted reproductive techniques,
with the necessary training, tools and laboratory support provided by CREW.
One objective of the grant is to contribute to the genetic management and propagation of captive Indian rhinos through artificial insemination (AI). Although AI in Indian rhinos is still a work in progress, the achievements made during CREW’s initial 8-year effort are impressive with six conceptions and four term calves produced. Because there is a steep learning curve to these procedures, we are hopeful that success will become even more common over time. Participating zoos agree to collect and ship rhino urine samples on a frequent basis to CREW for hormone analysis needed to time AI. Rhino keeper staff at each facility condition females to enter a chute for the purpose of performing AI and the standing sedation protocol already established for successful intrauterine AI in this species is implemented prior to expected ovulation date. Each facility observes one AI before performing the next AI under CREW supervision.
We are happy to report that the Denver Zoo team is now fully trained in Indian rhino AI and is performing procedures in house using sperm from CREW’s CryoBioBank. Our long-term commitment to rhino conservation has positioned us to respond to the growing need of zoos to build their capacity for assisted reproductive technology for rhinos. We are gladly meeting this challenge and enjoying establishing a network of RARE researchers united for a common cause – to save rhinos. A RARE endeavor indeed.
