　　In March this year, the 16-year-old giant panda "Cuicui" completed natural mating.

On July 10, "Cui Cui" had pregnancy behaviors such as reducing food intake and increasing activity. At 6:00 on August 4, the amniotic fluid broke, but there was no response to production.

After nearly 40 hours, the "heavyweight" cub was born at 21:39 on August 5, breaking the record of 249 grams of cubs born by the giant panda "Mei Qian" last year and becoming the birthplace of the world's captive giant panda. The heaviest panda cub.

　　"After 'Cuicui' broke the amniotic fluid, there was no production response. We were all worried about whether it would be difficult to give birth, and whether the cub would be in danger of hypoxia. Watching it pacing back and forth in the 'delivery room' and feeling irritable, we I am very anxious, but I can only monitor and observe 24 hours a day, quietly waiting and accompanying. I did not expect 'Cuicui' to give us a big surprise and gave birth to a 'heavyweight' baby." Responsible for taking care of the feeding of "Cuicui" The teacher said that "Cuicui" is a giant panda with strong motherhood and good ability to take care of babies. The last birth was in 2018. The birth weight of the babies born before it was more than 200 grams.

　　It is understood that every spring is the "blind date" season for giant pandas.

In March this year, the panda center's 2022 giant panda breeding work officially kicked off.

This year's giant panda breeding work insists on prenatal and postnatal care, with high-quality breeding as the core goal, scientifically selecting giant pandas to participate in breeding and mating.

As the giant pandas to give birth gradually enter the gestation period, breeders are on duty 24 hours a day. Through video surveillance and on-site observation, they conduct behavioral and physiological monitoring, analyze and judge in a timely manner, and provide guarantees for the smooth production of giant pandas and the safety of their cubs.

　　Since June this year, six giant pandas have given birth in succession at the Panda Center.

So far, the Panda Center has harvested 11 newborn cubs, 5 of which are twins.

The current farrowing season is expected to last until the end of August.
