Porn-watching pandas help unleash baby boom

Well, this doesn't have any correlation with Beijing 2008 other than Pandas being one of the Fuwas!

Nonetheless, I thought this is really funny!


---------------------------------------------------------

Picture this: pandas watching porn to procreate.

"It works," enthuses Zhang Zhihe, a leading Chinese expert, about showing uninitiated males DVDs of fellow pandas mating.

It's taken years of worldwide research and now scientists say they have unleashed a baby boom among one of the world's most beloved but endangered animals, China's giant panda.

A bit of panda porn has helped too, they say.




Pandas are known to be poor breeders and blue movies are just one of many techniques that have been tried to teach them to breed. The efforts to understand and simulate conditions for mating and raising cubs have paid off in China, the panda's native habitat.

Now it's a matter of successful mating outside China. The first test will come in January, when Prasertsak Buntragulpoontawee hopes to bring off a successful mating between male Chuang Chuang and partner Lin Hui in the northern Thailand city of Chiang Mai.

"It is the same idea as chimpanzees seeing people smoke and then copying it," says the Thai researcher.

Zhang, director of the Chengdu Research Base of Giant Panda Breeding, says this year's record high births is because of an accumulation of research on panda biology, nutrition and genetics while "trying to imitate nature better."

In the first 10 months of this year 31 cubs were born in captivity in China and 28 survived, said Zhang. That's an increase from 12 births in 2005 and just nine in 2000. Of this year's births, 14 came through natural breeding, while artificial insemination or a combination of the two produced the rest.

No cubs were born among the roughly 20 pandas outside China, but sperm from Atlanta Zoo's Yang Yang yielded an offspring for Lun Lun in Chengdu, China, Zhang told a conference here of 140 panda experts.

JoGayle Howard, an animal reproduction specialist at the Smithsonian Institution in Washington, D.C., said the goal of raising the captive breeding population to 300 from the current 220 is rapidly being reached. This would prevent inbreeding, widen the genetic pool and enable more captive animals to re-enter the wild, where the panda population is estimated at 1,600 to 3,000.

Howard said the biggest challenges in panda breeding are an extremely high rate of incompatibility and the very narrow window of opportunity -- females are ready to mate for as few as 48 hours a year.

"At first people thought that you just put two animals together and they would figure it out. But it didn't turn out that way," she said. "Now we know how to take care of the panda better. We've really made progress. But we're still learning a lot of even basic things.¡±

Howard explained that captive animals lacked proper socialization and when the male and female met for breeding ¡°they just freaked out and fought." Now enclosures are bigger and contain more animals.

There's also a push to keep cubs with their mothers longer, for up to two years, to give them more natural sex education.

In the wild females in heat will climb a tree while suitors below fight for her. In captivity, with no male rivals around, pandas often take out their aggression on the female.

"In the wild they have their own choices when mating," adds Zhang. "But when we breed them in captivity it's like taking two human beings and forcing them to mate."

There are still only about 15 captive male adults which breed naturally. Second best is artificial insemination, and after years of study frozen semen can now be shipped around the world and applied according to a comprehensive genetic database.

Prasertsak is prepared to use both methods as he readies his couple for mating at Chiang Mai Zoo, which has rented the animals from China for research and tourism purposes.

Last year Lin Hui showed promising symptoms but it turned out to be a pseudo-pregnancy, not unusual among pandas.

Opinions differ on the effect of blue movies, but Zhang and Prasertsak agree on the sound track.

"It's the sounds of breeding that stimulate them," Zhang said. "Pandas are just like human beings. They understand everything."
