According to Chongqing Daily, on October 13th, the giant panda Mangzai in Chongqing Zoo gave birth to a male baby for one hundred days, and it is about to collect names. Chongqing Zoo began to breed giant pandas in the 1960s, and began to breed giant panda cubs in the 1980s. At present, Chongqing Zoo has given birth to 31 pandas, and now there are 22 pandas, making it the largest city zoo in China.
A few days ago, the reporter interviewed the panda’s conservationists and learned the story behind their protection and breeding of the once endangered species, the "national treasure" giant panda.
Mangzai gave birth to the fattest baby panda.
On July 6th this year, Mangzai, a giant panda in Chongqing Zoo, successfully gave birth to a male baby. With a birth weight of 191g, the baby is the heaviest individual panda born in Chongqing Zoo.
Zhang Naicheng, director of the Panda Pavilion in Chongqing Zoo, remembers this vividly. “‘ Mangzai ’ In the delivery room, I enjoyed the happiness of being a mother, but our staff on duty tightened their nerves. " Zhang Naicheng told the reporter that from the prenatal period of Mangzai, the staff had several shifts, and the technical director and experienced nurses came. Chongqing Zoo also specially invited experts from Sichuan Wolong Giant Panda Breeding Center.
"Mangzai" has a strong maternal instinct and plenty of milk, and has been feeding her baby by herself. However, the staff still have concerns that the mother panda may be frightened by some unexpected situations and hurt her baby.
"This is a great test of our nurses’ ability to focus on keen insight. It is exaggerated to say that they can hear the sound of a needle falling in a quiet delivery room." Zhang Naicheng mentioned that it is normal to hear the cub’s voice very loud. If there is hoarse voice, further examination is needed. At the same time, we should also observe the frequency of the cub’s behaviors such as breastfeeding and defecation.
Under the careful care of the nurse, the baby’s weight has increased rapidly, and now it has reached 62.6 kg.
"Steal" the cub to keep it alive.
"This is the third time that the Panda Pavilion has been rebuilt and expanded. The Panda Pavilion was built in 1958, expanded for the first time in 1960 and expanded for the second time in 1988. It has the current name Panda Pavilion." Zhang Naicheng took the reporter to visit the new Panda Pavilion which has just been put into use recently.
"The 1980 s and 1990 s were the key years for giant panda breeding. Before that, the survival rate of giant panda breeding was very low." When Zhang Naicheng just joined the work, he heard from the master that Chongqing Zoo began to breed giant pandas in the 1980s, and it was only in 1985 that the first giant panda was successfully bred. None of them survived before.
"At that time, the conditions, technology and experience of giant panda breeding were lacking." Zhang Naicheng remembers that air conditioning was not installed in the Panda Pavilion before. In order to prevent the pandas from heatstroke, they needed to transport a lot of ice cubes to cool the pandas. If they meet a cub that needs artificial feeding, they use their bodies to warm the baby … … "Later, we had an incubator with a constant temperature of around 27 degrees." Zhang Naicheng said that in the 1990s, the emergence of incubators solved the problems of temperature and humidity.
In addition, twins are also a problem that restricts the breeding of giant pandas. After a giant panda gives birth to twins, it usually discards one and keeps only one. "In this case, one of the cubs ‘ Steal ’ And find a way to make it drink milk. " Zhang Naicheng said that it is difficult for cubs to survive if they can’t eat breast milk.
Thanks to technical improvement and accumulated experience, Zhang Naicheng and his colleagues witnessed the success of twin feeding. In 2006, Yaya, a giant panda in Chongqing Zoo, gave birth to twins. "Me and ‘ Yaya ’ Familiar, seize the opportunity of its distraction, stole the cub, that is, the later ‘ Youyou ’ 。” Zhang Naicheng recalled that in order to get breast milk, he once again risked getting close to Yaya and successfully obtained breast milk. Under the breast feeding, the twins survived healthily.
Young nurses are happy to take care of pandas.
Now, what makes Zhang Naicheng most happy is that the cause of giant panda breeding has not lost its appeal to young people, and a group of new people are gradually stirring up the beam, with more sound knowledge structure and more scientific breeding technology.
Liu Xiao, 30, is a "new wet nurse". She graduated from Southwest University with a major in animal science. She has worked in the Panda Pavilion for five years. "I am young among my colleagues, but I am not a novice." Liu Xiao told reporters.
"Pandas look cute, but they are actually very aggressive. It takes patience, love and professional knowledge to take care of them." Liu Xiao said that the nurse arrives at work before 8 am every day to clean and clean the bamboo leaves eaten by giant pandas … … "Our work is not as simple as ordinary cleaning. We should carefully observe how much food giant pandas ate yesterday and how much they defecated in one day. These are all references for judging the health status of giant pandas and need professional knowledge to analyze." Liu Xiao said.
After cleaning, Liu Xiao and his colleagues went into the kitchen to prepare "concentrated feed", including "Wowotou" made of biscuits, rice, corn, wheat, beef, fish and staple bamboo. At 10 o’clock in the morning, the nurse began to feed the giant panda, and observed the feeding situation and mental state of the giant panda at the same time. "Giant pandas need to eat five or six times a day, and every time we have to make a record, we should be patient to feed them day after day." Liu Xiao said.
"I am very happy to join the big family of giant panda caregivers. It is a very happy thing to take care of them when I come back every day." Liu Xiao said.
