On 1st September 2019, Beijing time, a pair of twin panda cubs were born by “Meng Meng” (6 years old) in Germany, According to the news, this was the first time a newborn panda was born out of the Sino-German international cooperation of breeding of giant pandas.
On 24th June, 2017, giant pandas “Meng Meng” and “Jiao Qing” left the Chengdu Giant Panda Research Base and headed to the Berlin Zoo in Germany. China and Germany officially launched the international scientific cooperation of research on giant pandas.
“Meng Meng” experienced her estrus period in late March of this year. After knowing this, the Panda Base immediately sent 2 experts of giant pandas to Germany to offer guidance for their breeding.
From 5th to 6th April, under the guidance of the experts from the Base, the Chinese and German teams worked together to proceed the artificial insemination of “Meng Meng”, which was also the only time in which an artificial insemination was done during the peak of estrus period of “Meng Meng”. Such an action had successfully impregnated “Meng Meng”.
Since August, the researchers have detected the continuous increase of hormone level of “Meng Meng”. The Panda Base immediately sent two experienced breeding experts of giant pandas to Germany to carry out comprehensive preparations for the birth and breeding of the newborn cubs.
At 22:20 on 31st August, Beijing time, “Meng Meng” had her amniotic fluid leaked out and was experiencing contraction of her uterus. The first cub was born at 00:52 on 1st September, and it weighed 186g. Then, the second cub was born at 01:43 in the morning, weighing 136g.
Although it was the first time “Meng Meng” gave birth to a cub, she showed her maternity entirely. When the cub was born, “Meng Meng” immediately held it in her arms, and was continuously licking its whole body with her tongue. Both cubs managed to be breastfed.
At present, the panda-rearing teams of both China and Germany are working together to take targeted measures to tackle any unfavorable situations of the cubs after birth. They put the two panda cubs in a nursery box and in the arms of their mother by turns. They also monitor their different indices real-time.
According to our understanding, the Panda Base has carried out scientific research and cooperation exchanges over giant pandas in 17 countries and regions.
Currently, it is conducting long-term research and breeding projects in seven countries, including Japan, the United States, Spain, France, Canada, Germany and Denmark. The overseas institutions provided by the Panda Base have bred 2/3 of the overseas giant pandas with only 1/3 of the population.
Up to 34 cubs have been bred, making the highest survival rate of giant pandas bred abroad. At present and in the Base, all the adult pandas participating in the research of international cooperation of breeding of giant pandas have successfully given birth to cubs.
