Zookeepers present a well being verify to one of many Big Panda cubs. (Toronto Zoo).

Jia Panpan and Jia Yueyue, the Toronto Zoo’s new panda cubs, are lastly on exhibit to the general public. At almost six months outdated, the celeb pandas debuted on Mar. 12, simply in time for Ontario’s March break. As Maclean’s explains in an unique look behind the gates, the general public frenzy hardly appears excessive in comparison with the trouble expended on the start and elevating of those cubs. As the pandas spend their first 5 days on show, right here are the 5 most fascinating particulars in regards to the coming of the cubs, a extremely intensive venture made even harder by the particular challenges of the species.

1. Keepers sneakily swapped twins out and in of the mom’s arms

Within the wild, pandas are all the time raised as solely youngsters. When a feminine offers start to twins, she chooses the stronger cub and both abandons or by accident crushes the smaller one. So to ensure that the Toronto Zoo to make sure equality, for the primary 4 months, seven panda keepers, working eight-hour shifts across the clock, carried out a course of known as “twin swapping.” One or two keepers would method the mom, named Er Shun, from the again and maintain a metal bowl of honey to her face to occupy her mouth. One other keeper would really feel round in Er Shun’s arms and pull out the cub. The keepers would weigh the cub to verify that it had drunk sufficient milk, then shortly afterwards hand Er Shun the dual. Er Shun might have recognized all alongside that she had two completely different cubs, however she put up with the dual swapping for the love of honey. She now spends time with each without delay.

2. Females can solely get pregnant for one to 3 days per 12 months

One of many primary the explanation why pandas are so endangered (with simply 1,868 left within the wild as of the final census), is as a result of the females have just one shot per 12 months to get pregnant. For the primary two years on the Toronto Zoo, Er Shun didn’t need to mate with the male panda on web site, Da Mao. As an alternative, the zoo needed to electro-ejaculate Da Mao, in addition to ask the Chengdu Analysis Base of Big Panda Breeding in China to ship sperm abroad. The method wasn’t easy …

3. Panda semen travelled aboard Air Canada and Air China

After Chengdu agreed to electro-ejaculate two male pandas and ship the sperm to Toronto, a man-made insemination skilled sealed the sperm in a canister of nitrogen vapour, with a layer of egg yolk to guard the pattern from the vapour. An skilled tried carrying the tank as carry-on as a result of it was too delicate to verify beneath the cabin. Not surprisingly, the baggage raised flags to the Beijing airport safety, and the skilled didn’t make it on the flight. The Canadian ambassador to China despatched an officer to resolve the safety difficulty and e-book the skilled on a flight the subsequent day. He arrived in Toronto round midnight on a Friday, and Er Shun hit her fertility window two days later. The keepers had been monitoring her hormones with urine samples, so that they knew precisely when to place her to sleep and inseminate her. Months later, the cubs had been born, and the parenting started.

4. Cubs can’t pee by themselves

Pandas are born after simply 45 days within the womb, so underdeveloped that their genders aren’t even obvious. Within the wild, moms have to lick round their cubs’ genitals to stimulate them to pee or defecate, however since Er Shun solely has one cub at a time, the Toronto zookeepers typically should stimulate the cubs themselves. The keepers maintain the cubs of their laps, rub round their bottoms with their fingers, and goal the bears’ bums over a rubbish can.

5. Cubs are handled like human infants

As a result of Er Shun doesn’t have sufficient milk for each twins, the panda keepers complement them with a combination of human child formulation, Enfamil A+, and pet formulation, measured with a recipe from China. The keepers maintain the cubs of their laps and allow them to suckle on a heat child bottle. (The cubs are actually being launched to bamboo, however their mouths aren’t but robust sufficient to eat it.) Since pandas are born so susceptible—at simply one-900th the dimensions of their mom—the cubs hung out in a human incubator donated by the SickKids hospital. They then graduated to a playpen with foam kiddy mats, and sooner or later they’ll get to climb a youngsters’s playground, which sits outdoors the panda home with the yellow slide eliminated.  Because the zoo’s reproductive specialist Gaby Mastromonaco explains, “quickly they’ll be operating round like rambunctious toddlers.”
