Panda cub dies at National Zoo

(CNN) — Veterinarians at the Smithsonian’s National Zoo in Washington have ruled out the possibility that a newborn giant panda cub was crushed by its mother, but an initial necropsy on the 4-ounce cub failed to provide a clear cause of death, officials said Monday.

The cub, believed to be a female, died Sunday, just six days after its widely celebrated birth. Just the size of a stick of butter, it had not yet been named.

The necropsy — the animal version of an autopsy — revealed the cub had some potentially unusual fluid in its abdomen and its liver was discolored and had hard in spots, said Dr. Suzan Murray, the zoo’s chief veterinarian.

But investigators won’t know if those findings are significant until lab tests and a full necropsy report come back in two weeks, she said. The initial exam revealed no obvious cause of death, zoo officials said. The cub had nursed, the exam showed, but it was unclear how well, Murray said.

The cub’s mother, Mei Xiang, cradled a toy throughout the night in place of her newborn cub, but she appeared to be healthy — eating and moving toward normal activity.

“I visited the keepers last night and early this morning,” National Zoo Director Dennis Kelly said. “They have reported to me the Mei is slowly returning to her routine, she has taken water, she has began eating both bamboo and biscuits and was offered fruit. I’m cautiously optimistic, based upon what the keepers and curators have told me, that she will slowly return to normal.”

The panda exhibit remained closed Monday but could reopen soon, Kelly said.

The death of the cub brought a crushing end to a joyous time at the zoo, where the birth of a new member of the highly endangered species was cause for celebration.

Public interest was also intense. In addition to a camera set up to view mother and cub, zoo officials had predicted the baby panda would push up attendance by a half-million people this year.

While Murray said it’s hard to find anything positive in the death, she said zoo officials hope that it will help them learn more about panda reproduction and health as they strive to protect the species.

The cub, conceived through artificial insemination, was 14-year-old mother Mei’s second in seven years with 15-year-old Tian Tian, the zoo’s male giant panda.

Kelly said the inquiry so far has found nothing that would indicate changes are necessary to the zoo’s breeding or care program.

“Nothing suggests that, in hindsight, we would do anything differently,” he said.

With a population of about 1,900, the giant panda is one of the most endangered species in the world. Kelly said investigators will carefully look at all the information associated with the cub’s death in an effort to learn lessons that could help in efforts to preserve the species.

“We’re going to learn from this,” he said.
