Longest-ever delivery results in heaviest panda cub in China
BEIJING (AFP) - A giant panda has scored two records in one go after the longest-ever delivery resulted in the heaviest cub to emerge from China's artificial breeding program, state media said.
Zhang Ka, aged six, gave birth to a 218-gram (7.6-ounce) male on Monday after spending 34 hours in labor at the China Wolong Giant Panda Protection and Research Center in the nation's southwest, the Xinhua news agency reported Tuesday.
Most panda cubs born in captivity weigh between 83 and 190 grams, Xinhua said, citing the China Giant Panda Breeding Technology Committee.
Thirty-four hours is a long time, even in the slow-moving world of the panda, and veterinarians were getting ready to perform a Caesarian when the pink creature emerged from its mother's womb by itself, Xinhua said.
According to the center in Sichuan province, Zhang Ka went into heat in early March and subsequently mated. Experts also performed artificial insemination to make sure she conceived, according to Xinhua.
The famously sexually inactive giant pandas are one of the world's most endangered species with an estimated 1,590 in the wild, mostly in the mountains of Sichuan.
Just over 180 more pandas, including those at Wolong, are in research centres in China, with a handful of others sent around the world to zoos.
Those numbers received a further boost with twin pandas each giving birth to twin cubs on Sunday and Monday at the Chengdu Giant Panda Reproduction and Research Center also in Sichuan, Xinhua reported in another dispatch.
Six pandas have now been born in captivity in China this year, Xinhua said.
Giant panda gives birth to giant cub
BEIJING (Reuters) - A giant panda in China has given birth to the heaviest cub born in captivity after the longest period in labor and elsewhere twin pandas each gave birth to twins, Xinhua news agency reported.
Six-year-old Zhang Ka delivered the baby on Monday at the Wolong Giant Panda Research Center in the mountainous southwest, Xinhua said.
The cub weighed just 218 grams (half a pound), but was still the heaviest panda ever born in captivity, where most cubs are born at between 83 and 190 grams, Xinhua said.
"It is very rare for them to be even near 200 grams," it said in a report late on Monday.
But the size and the fact that it was Zhang Ka's first meant a "painstaking and eventful" birth for the mother, who was born in the wild.
"The whole process lasted about 34 hours and was the longest in the history of panda reproduction," Xinhua quoted Zhang Hemin, head of the Wolong center, as saying.
Both mother and baby were doing well, the agency said.
Two twin panda sisters, also aged six, gave birth to two pairs of twin male cubs -- with much less drama -- on Sunday and Monday respectively in the Chengdu Giant Panda Reproduction and Research Center near Wolong, Xinhua said.
It brought the number of panda cubs born in captivity in China so far this year to six, it said.
The giant panda is one of the world's most exotic and endangered species and is found only in China, where it is a national treasure.
An estimated 1,600 wild pandas live in nature reserves in Sichuan, Gansu and Shaanxi provinces.
It is extremely hard to breed giant pandas in captivity. Females only ovulate once a year, with a slim 24- to 48-hour window for breeding when artificial reproduction methods are usually adopted. Infant mortality is also high.
Pandas eat bamboo shoots and spend a lot of time sleeping. They usually wean their young at around 18 months, and healthy pandas live into their late 20s or early 30s.
Twin pandas each have twin cubs in China
BEIJING - Twin giant pandas each gave birth to twin cubs this week as the number of pandas born in captivity this year in China rose to six, state media reported Tuesday.
The sisters, Qi Zhen and Qi Yuan, delivered their babies on Sunday and Monday at the Chengdu Giant Panda Reproduction and Research Center in Chengdu, the capital of southwest China's Sichuan province, where they live, the official Xinhua News Agency said.
A 7.7-ounce panda cub was born on Monday at the Wolong Giant Panda Protection and Research Center, elsewhere in Sichuan, and it became the heaviest cub in the history of China's artificial breeding program, according to the report.
Its mother, Zhang Ka, also set a record for the longest delivery after about 34 hours in labor, Xinhua said.
The first panda born in captivity this year was delivered at the Wolong center on June 22.
Female pandas normally become sexually mature between 4 and 5 years old. They can get pregnant once a year and usually give birth to one or two cubs at a time.
