The Panda Factories – The New York Instances

Two chunky pandas, a male and a feminine, arrived from China on the Nationwide Zoo in Washington on Tuesday. If all the things goes as deliberate, they are going to finally have cubs.

Exchanges like this have helped flip big pandas into the face of conservation worldwide.

The panda program was created with the acknowledged purpose of saving a beloved endangered species. Zoos would pay as much as $1.1 million a yr per pair, which might assist China protect the pandas’ habitat. By following fastidiously crafted breeding suggestions, zoos would assist enhance the genetic variety of the species.

And sometime, China would launch pandas into the wild.

However a New York Instances investigation, primarily based on greater than 10,000 pages of paperwork, has discovered that the Chinese language authorities and American zoos have put a rosy sheen on a program that has struggled, and sometimes failed, to satisfy these targets. The data, pictures and movies — a lot of them from the Smithsonian Establishment Archives — supply an in depth, unvarnished historical past of this system.

They present that, from the start, zoos noticed panda cubs as a pathway to guests, status and merchandise gross sales.

On that, they’ve succeeded.

Immediately, China has eliminated extra pandas from the wild than it has freed, The Instances discovered. No cubs born in American or European zoos, or their offspring, have ever been launched. The variety of wild pandas stays a thriller as a result of the Chinese language authorities’s rely is extensively seen as flawed and politicized.

Alongside the way in which, particular person pandas have been harm.

As a result of pandas are notoriously fickle about mating in captivity, scientists have turned to synthetic breeding. That has killed not less than one panda, burned the rectum of one other and brought on vomiting and accidents in others, data present. Some animals have been partly awake for painful procedures. Pandas in China have flickered out and in of consciousness as they have been anesthetized and inseminated as many as six instances in 5 days, way more typically than consultants suggest.

Breeding in American zoos has finished little to enhance genetic variety, consultants say, as a result of China usually sends overseas animals whose genes are already effectively represented within the inhabitants.

But American zoos clamor for pandas, and China eagerly gives them. Zoos get consideration and attendance. Chinese language breeders get money bonuses for each cub, data present. On the flip of the century, 126 pandas lived in captivity. Immediately there are greater than 700.

Kati Loeffler, a veterinarian, labored at a panda breeding middle in Chengdu, China, throughout this system’s early years. “I keep in mind standing there with the cicadas screaming within the bamboo,” she stated. “I noticed, ‘Oh my God, my job right here is to show the well-being and conservation of pandas into monetary acquire.’”

Dr. Loeffler, who spent a part of her time in Chengdu as a scholar affiliated with the Nationwide Zoo in Washington, stated that scientists there used anesthesia excessively and sloppily. At one level, she stated, she bucked protocol and jumped onto an examination desk to cradle an animal because it was being anesthetized.

Kimberly Terrell, who was director of conservation on the Memphis Zoo till 2017, stated, “There was at all times strain and the implication that cubs would carry cash.” She famous that zoo directors insisted on inseminating its ageing feminine panda yearly, regardless of considerations amongst zookeepers that it was unlikely to succeed. It by no means did.

“The individuals who truly labored day after day with these animals, who perceive them finest, have been fairly opposed to those procedures,” she stated. The zoo stated its breeding efforts adopted all program necessities. (Dr. Terrell, now a scientist at Tulane College in Louisiana, settled an unrelated gender discrimination lawsuit in opposition to the zoo in 2018.)

The Instances collected key paperwork and audiovisual supplies from the Smithsonian archives and supplemented them with supplies obtained via open-records requests. The trove, which spans 4 a long time, contains medical data, scientists’ discipline notes and pictures and movies that provide essential proof of breeding procedures, unwanted side effects and the circumstances wherein pandas have been held.

They present that the riskiest methods occurred in this system’s infancy, however that aggressive breeding continued on the Nationwide Zoo and at different establishments for years. A panda in Japan died throughout sperm assortment in 2010. Chinese language breeding facilities, till just lately, separated cubs from their moms to make the females return into warmth.

Pandas arrived in San Diego this summer season, and extra will probably land in San Francisco early subsequent yr. There are pandas in a steamy safari park in Indonesia and in an air-conditioned dome in Qatar. So many pandas are in captivity in China that a number of new vacationer sights are being constructed.

This panda proliferation has prompted debates amongst zoo employees and scientists over whether or not it’s moral to topic animals to intensive breeding once they don’t have any actual prospect of being launched into the wild. However these discussions have largely performed out privately as a result of researchers and zookeepers stated that criticizing this system might harm their capacity to work within the discipline.

Veterinary medication is at all times dangerous, particularly with wild animals. When an animal’s life is in peril, the advantages of intervening outweigh the dangers. And when a species is on the verge of extinction, conservationists typically make a last-ditch effort to reserve it.

However with pandas, zoo directors take probabilities repeatedly merely to make extra cubs, whereas preserving the grimmest particulars from the general public.

On the middle of this story is the Nationwide Zoo, which is a part of the Smithsonian. Pandas have been a part of the zoo’s picture since 1972, when President Richard M. Nixon traded a pair of musk oxen for 2 bears after his historic journey to China.

However the Smithsonian has glossed over the truth of synthetic breeding, at instances in partnership with the Chinese language propaganda equipment, data present.

American zoos say that preserving and breeding pandas has expanded scientific understanding of the species. “Crucial intervention, together with conservation breeding, has been obligatory for the survival of big pandas,” the San Diego Zoo stated in an announcement.

A Nationwide Zoo spokeswoman, Annalisa Meyer, acknowledged that efforts to launch pandas into the wild have been “nonetheless growing,” and he or she stated that this system’s success couldn’t be measured within the variety of animals launched. She stated that pandas in zoos have been “insurance coverage in opposition to extinction” and that animal security was a high precedence.

Western cash and a focus have additionally coincided with China’s enlargement of nature reserves and stricter logging guidelines.

Having pandas in zoos additionally exhibits that individuals around the globe love, and wish to defend, the species, stated Melissa Songer, a Smithsonian conservation biologist.

Pandas in captivity are cussed breeders. Females are fertile for, at finest, three days a yr. Males will be aggressive or incompetent companions.

However in one of many program’s nice ironies, the search to avoid wasting pandas could also be making it more durable for them to breed.

Data present that zoos have lengthy identified that preserving pandas in captivity made it much less probably that they might mate. Big pandas in zoos typically have a “lack of regular behaviors leading to reproductive failure,” the Nationwide Zoo wrote in an early analysis proposal.

Heather Bacon, a veterinarian on the College of Central Lancashire, in northwestern England, stated people set the phrases. “We select how they breed. In the event that they don’t wish to breed, we make them breed,” stated Dr. Bacon, a director of the Bear Care Group, which works intently with zookeepers. “And the justification for that’s at all times, quote-unquote, conservation. Is {that a} real justification?”

“As a result of all we’re doing,” she added, “is producing extra pandas to dwell in captivity and have those self same experiences over and over.”

The panda program was supposed to repair abuses.

Within the Nineteen Eighties, China despatched pandas for brief stints to international zoos, the place they rode bicycles and pushed trollies, like carnival sideshows. Many had been caught within the wild. It took a lawsuit for U.S. regulators to intervene.

After years of negotiation, American zoos and the Chinese language authorities struck a deal, and the U.S. Fish and Wildlife Service issued a coverage in 1998. Zoos might hire pandas for a decade at a time, with the cash going towards conservation.

American and Chinese language scientists additionally agreed to collectively research panda breeding. The inhabitants in captivity confirmed indicators of inbreeding. Synthetic insemination efforts had faltered.

So, within the late Nineties and early 2000s, scientists from the Nationwide Zoo, San Diego Zoo and different establishments flew to the Sichuan Province of China. Archival pictures and data reveal particulars of journeys which have seldom been mentioned however that laid the muse for breeding around the globe.

Researchers shot pandas with tranquilizer darts to anesthetize them, then laid them on stretchers or boards. Bundled up in opposition to the chilly in spartan concrete rooms, scientists collected semen from the males by inserting electrified probes into their rectums.

They known as themselves the “Sperm Group.”

This method, known as electroejaculation, is often utilized in captive breeding. However the scientists drugged among the animals with unadulterated ketamine, a strong sedative that veterinarians usually use together with different medication. Ketamine alone can go away an animal anxious and in ache — and partly awake, as a Nationwide Zoo veterinarian acknowledged in a presentation on the time.

Some pandas have been “mild,” which means they have been insufficiently anesthetized, and apparently struggled.

“Animal was mild throughout complete process,” JoGayle Howard, a scientist on the Nationwide Zoo, wrote in a journal she stored on a 1999 journey. “Virtually got here off desk at one level (used ketamine solely this time as an alternative of ketamine and xylazine).”

“Nice semen pattern with excessive rely,” she added.

Throughout one assortment, Dr. Howard wrote that Chinese language scientists had quadrupled the voltage to an unsafe 12 volts.

“They used dangerously excessive voltages and too many stimulations on male Ping Ping after we left,” she wrote. “Male had bloody free stool and no urge for food for months.”

Consultants say that electroejaculation ought to be finished cautiously, with minimal voltage. “You are able to do numerous hurt,” stated Thomas Hildebrandt, an skilled on synthetic breeding in animals at Leibniz Institute for Zoo and Wildlife Analysis in Berlin.

The Chengdu Analysis Base of Big Panda Breeding, which right this moment owns one-third of the world’s captive pandas, denied ever utilizing extreme voltage or in any other case harming animals. “Now we have not had any big pandas endure well being harm or dying throughout surgical procedure as a consequence of using ketamine,” the middle stated in an announcement.

Dr. Hildebrandt stated that synthetic insemination ought to be finished as soon as per cycle, after pinpointing the second a feminine is most fertile.

However Chinese language scientists inseminated feminine pandas repeatedly. In a single experiment, they inseminated seven females, sedated with solely ketamine, as typically as six instances per animal in 5 days, which means the pandas have been out and in of stupors.

Notes within the Smithsonian archive present that American scientists by chance injured one panda’s uterus throughout an examination. Images present pandas vomiting. “Troublesome anesthesia,” scientists wrote a couple of feminine panda named Lei Lei at a breeding middle in Wolong, western China. “Retching and vomiting. Insufficient fasting — meals and water. Process minimize quick.”

Lots of the scientists from that period have retired or died, and the Nationwide Zoo stated it had no data of pandas in China being injured. It stated that scientists had restricted data about panda replica on the time. Ms. Meyer, the spokeswoman, stated this early analysis interval contributed to improved care and a “panda child growth.”

Notes clarify that the scientists didn’t intend to hurt the animals. They believed they have been saving the species. In conservation efforts, the welfare of the species typically trumps that of particular person animals.

Dr. Howard grew to become a conservation hero, now memorialized in a Chengdu museum.

However the scientists set in movement a frenzied push to make pandas that continues right this moment.

For many years, the Chinese language zoo affiliation has given $1,400 bonuses to breeding facilities and zoos for each cub that lives to 6 months. Those that make “particular achievements” can earn as much as $7,050.

The Chengdu middle’s price range final yr included targets for pregnancies and cubs.

That creates an incentive to breed animals as rapidly as attainable.

In 2017, Lung Yuan Chih, then a researcher with Tsinghua College in Beijing, visited three Chinese language breeding facilities for her dissertation. All three did a number of electroejaculations or fertilizations on every panda chosen for breeding, stated Dr. Lung, who’s now a director of the Taiwan Human-Animal Research Institute.

A wholesome species has a various number of genes, making it extra more likely to adapt to sicknesses or habitat adjustments. That’s the reason American scientists helped create detailed suggestions for which pandas ought to breed.

These suggestions have been typically ignored, data present. As an alternative, the Chinese language facilities primarily targeted on animals that have been simple breeders.

Breeding facilities additionally prematurely separated cubs from their moms.

Within the wild, cubs stick with their moms for 18 months to 2 years. Throughout that point, females are unlikely to enter estrus, or warmth. To make the moms fertile once more, zookeepers have taken cubs away a lot earlier.

“Typically the moms didn’t have any break in any respect,” stated one Chinese language former panda keeper who labored on breeding and spoke on the situation of anonymity as a result of he feared reprisal. “They gave delivery yearly.”

Within the mid 2000s, cubs have been moved to nurseries shortly after delivery. Later, many have been positioned with “stepmothers” — primarily panda moist nurses.

Pandas give delivery to 1 or two cubs at a time. Chinese language panda fanatics who monitor webcam footage documented a feminine on the Chengdu middle in 2017 caring for six cubs.

James Ayala, an American behavioral researcher there, stated that the middle stored cubs with their moms at any time when attainable. Stepmothers are used solely when moms reject their cubs, he stated. “Now we all know that preserving them with the mother is tremendous, tremendous, tremendous important,” he stated.

Dr. Hildebrandt, the factitious breeding skilled, stated that he had labored with the middle and that practices have been bettering.

A Instances reporter visited Chengdu final month. The middle licensed Mr. Ayala to talk however declined to make directors, scientists or panda keepers accessible.

Throughout the interview, employees members and native propaganda officers repeatedly interjected to flag subjects that have been off-limits. These included the discharge of pandas into the wild and synthetic insemination.

In a latest article titled, “‘Electrocution’ of Big Pandas! Can It Be True?” the zoo says that synthetic breeding is innocent.

When they’re sufficiently old, pairs of Chinese language pandas are eligible to be rented.

Beneath the coverage governing the rental program, zoos might not revenue from pandas.

However data present that, at the same time as this system particulars have been being hashed out, cash was on the middle of the dialogue.

In 1993, zoo representatives from the USA and Europe gathered on the Nationwide Zoo to strategize.

The notes from that assembly are filled with typos, however they present that zoo directors weren’t inquisitive about solely displaying a uncommon species. They needed cubs, referring to the agreements as “breeding loans.”

“Outdated males,” stated a Nationwide Zoo scientist on the assembly, should not “going to herald as a lot cash as a breeding pair.”

Some attendees acknowledged that transport pandas around the globe did little to guard them. “If we have been actually within the conservaitonof of the panda,” the notes learn, “then we’d contribute to them insitu [in the wild] and nont take them out.”

Immediately, American zoos should submit audits of their panda-related income to the Fish and Wildlife Service to show that they aren’t profiting. Pandas are costly. Past hire to China, zoos additionally must construct refined enclosures and purchase tons of bamboo.

However pandas entice huge donors.

In 1999, earlier than its final pandas arrived, the Nationwide Zoo launched a $13 million fund-raising marketing campaign, which included $10.5 million for what it known as an “training middle.”

An inner doc from that interval suggested staff to deflect a journalist’s questions in regards to the venture’s deliberate present store, restaurant, particular occasions space and fund-raising workplaces. The constructing is the zoo’s “funding in the way forward for wildlife on Earth,” the doc reads. “In order that’s why we wish to construct the ed facility!”

The zoo, a nonprofit, doesn’t cost for admission. However paperwork present that it noticed pandas as a method to “type sturdy collaborations with space companies.”

It brokered panda sponsorship offers with Fujifilm and Animal Planet; labored with native motels to create packages that included zoo donations; and sourced panda mouse pads, golf balls and shot glasses for the present retailers.

Inside months of the pandas Mei Xiang and Tian Tian arriving, a million guests had come via the gates.

However the pandas struggled.

Scientists have constantly noticed panda “stereotypies,” or behaviors related to captivity. San Diego Zoo scientists studied 47 captive pandas around the globe and, in paperwork submitted to regulators, stated that just about two-thirds did issues like “pacing, head tossing, pirouetting and stereotypic cage climbing.”

Circumstances in China throughout these early years might have made issues worse. A San Diego scientist wrote to a Nationwide Zoo panda keeper that pandas typically had issues arising from what he known as their “jail cell” stint in “clearly substandard housing.”

For Mei Xiang and Tian Tian, the climate was a problem. Pandas want a cool mountain local weather, and by April 2001, the pair languished within the Washington warmth.

“Panting,” medical notes learn repeatedly. The zoo resorted to ice blocks, hosing and air-conditioning. A spokeswoman stated that the zoo follows temperature and climate tips.

Mei Xiang had irregular stools after being overfed throughout behind-the-scenes excursions, a keeper wrote. When the zoo threw her a celebration to rejoice her millionth customer, she slept via it.

As mates, Mei Xiang and Tian Tian weren’t an ideal match.

“Tian Tian violently attacked Mei Xiang,” a veterinarian wrote in 2002, after an early mating encounter. Later mating makes an attempt failed.

So employees intervened. Mei Xiang gave delivery in 2005 after a single spherical of synthetic insemination.

Subsequent conceptions proved elusive. Scientists started packing a number of procedures into Mei Xiang’s transient fertile window.

Beneath federal coverage, zoos can not breed pandas merely to make cubs. Zoo notes from that interval present that employees have been repeatedly reminded that breeding was about science, not cubs.

Directors tracked the efforts.

“Sadly, this was the fourth yr in a row that Mei Xiang has not been in a position to conceive,” the director reported to the zoo’s advisory board in 2010.

The next yr was notably tough. Mei Xiang vomited after her first insemination. When employees anesthetized her for the second, about 24 hours later, the dart didn’t totally discharge. Mei Xiang was darted 4 instances that day, resulting in a tough restoration.

Ms. Meyer, the Nationwide Zoo spokeswoman, stated that breeding was intently monitored and adopted protocol.

In 2011, the zoo introduced that if Mei Xiang failed to provide a cub the following yr, it would ship her again to China.

Mei Xiang finally produced 4 surviving cubs after not less than 21 rounds of synthetic insemination. Few of the small print have been made public, and the Smithsonian has refused to launch some details about them via an open-records request.

Years later, in 2022, the Smithsonian Channel made a movie about her final cub, “The Miracle Panda,” with an organization that’s a part of China’s propaganda equipment. It introduced synthetic breeding as fast, efficient and minimally invasive.

The zoo spokeswoman stated that filmmakers who wanted entry to China have been required to work with sure manufacturing firms. The Smithsonian reviewed the movie for “scientific accuracy,” she stated.

Virtually instantly after every delivery, cash poured in.

“General merchandise gross sales have elevated dramatically,” reads a 2006 doc from the zoo’s fund-raising companion.

“Funds a lot zoo operations, analysis, training programming,” an worker scrawled on a notepad.

Customer totals shot up and by 2010, data present, 9 out of the ten best-selling gadgets have been panda-related.

Consultants say that China usually retains its most genetically invaluable animals within the nation. At one level, data present, Tian Tian and Mei Xiang had “the bottom score” as a pair.

The zoo says that their cubs are wholesome and genetically essential. “They’re a part of the breeding program” in China, stated Pierre Comizzoli, a Smithsonian reproductive skilled who led lots of the inseminations. “So that is extraordinarily essential.”

At one level, although, data present that consultants mentioned utilizing a personal jet to fly sperm from a panda in San Diego that was a “way more acceptable” genetic match.

“Scientifically, these animals should not essential to the inhabitants,” Mads Frost Bertelsen, the zoological director on the Copenhagen Zoo, stated of the pandas despatched abroad. His zoo has pandas, however has not used synthetic insemination, he stated. “The one motive to do it proper now can be a monetary one. We might get extra income if we had cubs.”

Two chunky pandas, a male and a feminine, arrived from China on the Nationwide Zoo in Washington on Tuesday. If all the things goes as deliberate, they are going to finally have cubs.

Exchanges like this have helped flip big pandas into the face of conservation worldwide.

The panda program was created with the acknowledged purpose of saving a beloved endangered species.

When they’re sufficiently old, pairs of Chinese language pandas are eligible to be rented.

Beneath the coverage governing the rental program, zoos might not revenue from pandas.

However data present that, at the same time as this system particulars have been being hashed out, cash was on the middle of the dialogue.

In 1993, zoo representatives from the USA and Europe gathered on the Nationwide Zoo to strategize.

The notes from that assembly are filled with typos, however they present that zoo directors weren’t inquisitive about solely displaying a uncommon species. They needed cubs, referring to the agreements as “breeding loans.”

“Outdated males,” stated a Nationwide Zoo scientist on the assembly, should not “going to herald as a lot cash as a breeding pair.”

Some attendees acknowledged that transport pandas around the globe did little to guard them. “If we have been actually within the conservaitonof of the panda,” the notes learn, “then we’d contribute to them insitu [in the wild] and nont take them out.”

Immediately, American zoos should submit audits of their panda-related income to the Fish and Wildlife Service to show that they aren’t profiting. Pandas are costly. Past hire to China, zoos additionally must construct refined enclosures and purchase tons of bamboo.

However pandas entice huge donors.

In 1999, earlier than its final pandas arrived, the Nationwide Zoo launched a $13 million fund-raising marketing campaign, which included $10.5 million for what it known as an “training middle.”

An inner doc from that interval suggested staff to deflect a journalist’s questions in regards to the venture’s deliberate present store, restaurant, particular occasions space and fund-raising workplaces. The constructing is the zoo’s “funding in the way forward for wildlife on Earth,” the doc reads. “In order that’s why we wish to construct the ed facility!”

The zoo, a nonprofit, doesn’t cost for admission. However paperwork present that it noticed pandas as a method to “type sturdy collaborations with space companies.”

It brokered panda sponsorship offers with Fujifilm and Animal Planet; labored with native motels to create packages that included zoo donations; and sourced panda mouse pads, golf balls and shot glasses for the present retailers.

Inside months of the pandas Mei Xiang and Tian Tian arriving, a million guests had come via the gates.

However the pandas struggled.

Scientists have constantly noticed panda “stereotypies,” or behaviors related to captivity. San Diego Zoo scientists studied 47 captive pandas around the globe and, in paperwork submitted to regulators, stated that just about two-thirds did issues like “pacing, head tossing, pirouetting and stereotypic cage climbing.”

Circumstances in China throughout these early years might have made issues worse. A San Diego scientist wrote to a Nationwide Zoo panda keeper that pandas typically had issues arising from what he known as their “jail cell” stint in “clearly substandard housing.”

For Mei Xiang and Tian Tian, the climate was a problem. Pandas want a cool mountain local weather, and by April 2001, the pair languished within the Washington warmth.

“Panting,” medical notes learn repeatedly. The zoo resorted to ice blocks, hosing and air-conditioning. A spokeswoman stated that the zoo follows temperature and climate tips.

Mei Xiang had irregular stools after being overfed throughout behind-the-scenes excursions, a keeper wrote. When the zoo threw her a celebration to rejoice her millionth customer, she slept via it.

As mates, Mei Xiang and Tian Tian weren’t an ideal match.

“Tian Tian violently attacked Mei Xiang,” a veterinarian wrote in 2002, after an early mating encounter. Later mating makes an attempt failed.

So employees intervened. Mei Xiang gave delivery in 2005 after a single spherical of synthetic insemination.

Subsequent conceptions proved elusive. Scientists started packing a number of procedures into Mei Xiang’s transient fertile window.

Beneath federal coverage, zoos can not breed pandas merely to make cubs. Zoo notes from that interval present that employees have been repeatedly reminded that breeding was about science, not cubs.

Directors tracked the efforts.

“Sadly, this was the fourth yr in a row that Mei Xiang has not been in a position to conceive,” the director reported to the zoo’s advisory board in 2010.

The next yr was notably tough. Mei Xiang vomited after her first insemination. When employees anesthetized her for the second, about 24 hours later, the dart didn’t totally discharge. Mei Xiang was darted 4 instances that day, resulting in a tough restoration.

Ms. Meyer, the Nationwide Zoo spokeswoman, stated that breeding was intently monitored and adopted protocol.

In 2011, the zoo introduced that if Mei Xiang failed to provide a cub the following yr, it would ship her again to China.

Mei Xiang finally produced 4 surviving cubs after not less than 21 rounds of synthetic insemination. Few of the small print have been made public, and the Smithsonian has refused to launch some details about them via an open-records request.

Years later, in 2022, the Smithsonian Channel made a movie about her final cub, “The Miracle Panda,” with an organization that’s a part of China’s propaganda equipment. It introduced synthetic breeding as fast, efficient and minimally invasive.

The zoo spokeswoman stated that filmmakers who wanted entry to China have been required to work with sure manufacturing firms. The Smithsonian reviewed the movie for “scientific accuracy,” she stated.

Virtually instantly after every delivery, cash poured in.

“General merchandise gross sales have elevated dramatically,” reads a 2006 doc from the zoo’s fund-raising companion.

“Funds a lot zoo operations, analysis, training programming,” an worker scrawled on a notepad.

Customer totals shot up and by 2010, data present, 9 out of the ten best-selling gadgets have been panda-related.

Consultants say that China usually retains its most genetically invaluable animals within the nation. At one level, data present, Tian Tian and Mei Xiang had “the bottom score” as a pair.

The zoo says that their cubs are wholesome and genetically essential. “They’re a part of the breeding program” in China, stated Pierre Comizzoli, a Smithsonian reproductive skilled who led lots of the inseminations. “So that is extraordinarily essential.”

At one level, although, data present that consultants mentioned utilizing a personal jet to fly sperm from a panda in San Diego that was a “way more acceptable” genetic match.

“Scientifically, these animals should not essential to the inhabitants,” Mads Frost Bertelsen, the zoological director on the Copenhagen Zoo, stated of the pandas despatched abroad. His zoo has pandas, however has not used synthetic insemination, he stated. “The one motive to do it proper now can be a monetary one. We might get extra income if we had cubs.”
