Cheetah cubs born for the 1st time through surrogacy
The third time was a charm for biologists trying to successfully transfer embryos from one cheetah to another.
Cheetahs are endangered — there are only about 7,000 in the wild — and it's difficult for them to reproduce after age 8. But researchers determined that genetically, a 9-year-old female cheetah at the Columbus Zoo named Kibibi was a good match for a 3-year-old male named Slash living at the Fossil Rim Wildlife Center in Texas.
The Columbus Zoo, the Smithsonian's National Zoo and Conservation Biology Institute, and Fossil Rim Wildlife Center worked together to devise a plan to have the pair somehow reproduce. In November, Kibibi received hormone injections to stimulate follicle development and had several eggs extracted and fertilized with frozen sperm from Slash. These embryos were implanted in a 3-year-old cheetah named Izzy, and an ultrasound in December showed she was pregnant with two fetuses. This was the third time they attempted the process, and the first time it worked.
Izzy gave birth on Feb. 19 to a male weighing 480 grams and a female weighing 350 grams. She is providing "great care" to the cubs, the Columbus Zoo told ABC News. The cubs don't have names yet, and won't be on display for several months. This is a "big win for the cheetah," Jason Ahistus of the Fossil Rim Wildlife Center said in a statement. "It really opens the door to many new opportunities that can help the global cheetah population."
