BEIJING: Hopes that tiny panda paws would be seen in the world's first live-broadcast cub delivery were dashed Tuesday when Chinese experts suggested the "mother" may have been focusing more on extra bun rations than giving birth.
The slated star of the show, giant panda Ai Hin, had last month shown signs of pregnancy at the Chengdu Giant Panda Breeding Research Center, according to state news agency Xinhua.
A live broadcast of the event was planned, but Xinhua said her "behaviors and physiological indexes returned to normal," citing experts saying she experienced a "phantom pregnancy."
The breeding center, in China's southwestern province of Sichuan, commonly moves pandas which are thought to be pregnant into single rooms with air conditioning and around-the-clock care.
"They also receive more buns, fruits and bamboo, so some clever pandas have used this to their advantage to improve their quality of life," Wu Kongju, an expert at the base told Xinhua.
Phantom pregnancy is said to be common among the endangered animals, and many bears continue to display pregnant behavior after noticing the difference in treatment they receive, Xinhua said.
Six-year-old Ai Hin experienced reduced appetite, less mobility and a surge in hormones when her "pregnancy" was first detected, the news agency said, before further observations concluded it was fake.
The giant panda's natural habitat is in the mountainous southwest of China. But the bears have a notoriously low reproductive rate and are under pressure from factors such as habitat loss.
China has about 1,600 pandas living in the wild and another 300 held in captivity.
"Only 24 percent of females in captivity give birth, posing a serious threat to the survival of the species," Xinhua said.
