Successful artificial insemination in the Asian elephant (Elephas maximus) using chilled and frozen-thawed semen
BACKGROUND Artificial insemination (AI) using frozen-thawed semen is well established and routinely used for breeding in various mammalian species. However, there is no report of the birth of elephant calves following AI with frozen-thawed semen. The objective of the present study was to investigate the fertilizing ability of chilled and frozen-thawed semen in the Asian elephant following artif...
متن کاملThe in vitro quality of frozen-thawed Asian elephant (Elephas maximus) spermatozoa in semen supplemented with Equex STM paste and oxytocin during and after cryopreservation.
The effects of Equex STM paste (Equex) and oxytocin (OT) on the in vitro quality of frozen-thawed Asian elephant sperm were investigated in the study. The viability of frozen-thawed sperm was significantly higher in the Equex-treated (1 and 2%) groups than in the control group. There were no differences in the examined sperm parameters among the control and OT-treated (0.05-5IU) groups.
متن کاملLow coverage sequencing of two Asian elephant (Elephas maximus) genomes
BACKGROUND There are three species of elephant that exist, the Asian elephant (Elephas maximus) and two species of African elephant (Loxodonta africana and Loxodonta cyclotis). The populations of all three species are dwindling, and are under threat due to factors, such as habitat destruction and ivory hunting. The species differ in many respects, including in their morphology and response to d...
متن کاملEvaluation of post-thaw Asian elephant (Elephas maximus) spermatozoa using flow cytometry: the effects of extender and cryoprotectant.
Although the development of semen cryopreservation in the African elephants (Loxodonta africana) has been accomplished, effective procedures for cryopreservation of Asian elephant (Elephas maximus) spermatozoa have not been established. In the present study, we investigate the freezing methods for conservation of Asian elephant spermatozoa under field conditions and identify the most suitable f...
متن کاملSummation by Asian Elephants (Elephas maximus)
Recent empirical evidence for complex cognition in elephants suggests that greater attention to comparative studies between non-human primates and other animals is warranted. We have previously shown that elephants possess the ability to judge the difference between two discrete quantities, and unlike other animals, their choice does not appear to be affected by distance or overall quantity. In...
