Rhino in San Diego pregnant, could help save subspecies
SAN DIEGO — A southern white rhino has become pregnant through artificial insemination at the San Diego Zoo Safari Park — giving hope for efforts to save a subspecies of one of the world’s most recognizable animals, researchers announced Thursday.
Scientists will be watching closely to see if the rhino named Victoria can carry her calf to term over 16 to 18 months of gestation.
If she does, researchers hope someday she could serve as a surrogate mother and could give birth to the related northern white rhino, whose population is down to two females after decades of decimation by poachers. The mother and daughter northern white rhinos that live in a Kenya preserve are not capable of bearing calves.
The last northern white male rhino, named Sudan, was euthanized in March at the Kenya preserve because of ailing health related to his old age.
Victoria is the first to become pregnant of six female southern white rhinos the San Diego Zoo Institute for Conservation Research is testing to determine if they are fit to be surrogate mothers. If they pass the testing, they could carry northern white rhino embryos sometime within the next decade as scientists work to re-create northern white rhino embryos.There are no northern white rhino eggs so creating an embryo would require using genetic technology.
Victoria is a healthy 747-pound (1,700-kilogram) rhino estimated to be 7 years old. There are about 20,000 southern white rhinos in Africa.
