A San Diego conservation organization says it has accomplished the first successful artificial insemination start of a southern white rhino in North America, a crucial step in saving another rhino species from extinction.
San Diego Zoo Global introduced that mother Victoria gave start Sunday to a healthy southern white rhino male calf in the barn on the San Diego Zoo Safari Park after 30 minutes of labor.
Mother rhino Victoria was artificially inseminated with frozen semen from Maoto a southern white rhino in March 2018 following hormone-induced ovulation. Victoria carried her calf for over a year for 493 days. Mother and calf will stay off exhibit to the public to allow them time to bond for now.
The calf will eventually be launched to the opposite five female rhinos on the Nikita Kahn Rhino Rescue Heart — including Amani, one other rhino pregnant by artificial insemination due to give beginning in September or October.
The northern white rhino is an isolated subspecies of the southern white rhino. Only two northern white rhinos currently stay on Earth — each female.
Scientists say the southern white rhinos will be attending as surrogates for northern white rhino embryos. The reproductive system of rhinos could be very complicated, but researchers are confident that a northern white rhino calf could be born from these methods inside 10 to 20 years.
In May, scientists on the Polish zoo Chorzow efficiently completed a process the place they transferred a northern rhino test-tube embryo again right into a female southern white rhino whose eggs had been fertilized in vitro. Nonetheless, the embryo transferred at Chorzow zoo is smaller than expected. It stays to be seen whether it will implant in the mother’s uterine lining and end in a pregnancy.
The last male northern white rhino, named Sudan, died on March 2018. Scientists had preserved frozen sperm samples from several males they are hoping to use to restore the species.
