Elephant sperm storeage

Artificial insemination AI plays a key role in genetic management of elephants in captivity. Currently, freshly extended or chilled semen is used in all AI attempts. To maximize AI efficiency, it has become imperative to optimize conditions for liquid storage and semen transport. After 24 h of storage, African elephant spermatozoa exhibited greater longevity and higher values in sperm quality parameters compared to Asian elephants.

Customer Interview: Preserving the Endangered Asian Elephant | BD Biosciences-US

A: The Asian elephant Elephas maximus is listed as an endangered species, with an estimated 30,—50, individuals worldwide. Our goal is to enhance their breeding efforts by optimizing semen storage and sperm cryopreservation techniques with the simultaneous use of artificial insemination. More importantly, the development of sperm cryopreservation technology will allow us to establish a genome resource bank GRB for Asian elephants and provide genetic insurance for this endangered species. Although Asian elephants in the wild are not poached for ivory like African elephants only the males have tusks , the major threats are human encroachment and habitat destruction. Wild populations are becoming more fragmented, threatening their genetic diversity. The creation of a GRB will allow us to preserve the genetic diversity of the elephant population and ultimately prevent a genetic bottleneck. Q: What is the role of captive elephants in the preservation of the wild population?

Research: Liquid Semen Storage in Elephants

F Corresponding author. Email: gvdhorst7 gmail. This study aimed to address the lack of information on quantitative semen and sperm characteristics of free-ranging African elephants. While most elephant cows are in oestrus in the rainy season, it is not evident whether sperm quality also improves during this period. Semen samples were assessed using computer-aided sperm analysis CASA , brightfield microscopy and transmission electron microscopy.

Overall and specific conservation needs this project addressed The population of Asian elephants in captivity in North America is currently not self —sustaining Wiese There are numerous reasons for this, not the least of which is the lack of bull elephants in captivity. As a result, many zoos are now attempting artificial insemination AI to increase reproduction and maximize the genetic diversity of the captive population. Cryopreservation of semen for use with artificial insemination has the potential to be a valuable tool in the management of captive elephants. Cryopreserved semen has the advantage that it can be collected at any time and frozen indefinitely until needed, overcoming the need to collect semen shortly before it is needed and the risk of quality inconsistency that is found with chilled semen.
