Veterinarians Viewed Surprising Giant Panda Ultrasound at Smithsonian’s National Zoo
For the first time at the National Zoo, veterinarians detected something new during an ultrasound procedure this morning on giant panda Mei Xiang. They believe it is a developing giant panda fetus. Based on the size of the fetus, which is about four centimeters, veterinarians estimate that Mei Xiang could give birth early next week, or possibly in early September. In past years, veterinarians have only detected changes to Mei Xiang’s uterus, which occurs for both a pregnancy and pseudopregnancy. Historically, and since Aug. 7 of this year, Mei Xiang declined participating in ultrasounds at this stage, so it was a surprise when she responded to the panda keepers’ calls this morning.
