Panda Cub's Death Caused by Lung and Liver Problems
The National Zoo's panda cub died of a combination of lung and liver problems, zoo officials announced in a press conference Thursday morning.
The lungs of the six-day-old female cub were not fully formed, according to a necropsy. As a result, her liver didn't get enough oxygen, causing damage that led to her death Sept. 23. The cub may have been born prematurely, the zoo said.
The mortality rate for females born in captivity is 20 percent in the first year.
