At 42.8g, the World's Smallest Panda Cub Safely Born in Chengdu
On June 11, giant panda Cheng Da at the Chengdu Research Base of Giant Panda Breeding safely gave birth to a female panda cub that came in at a weight of 171.9g. Thereafter in the evening, Chengdu Da gave birth to another female cub that weighted merely 42.8g, which was lighter than Wu Yi, then world record-holder for the lightest surviving panda cub, becoming the world's smallest panda cub in existence. At present, the base has arranged for a cub caring expert team to feed, monitor and nurse the newborn around the clock, including constant monitoring of its breathing, mental condition and feces. Although vital signs have remained at a stable level, but there are still a lot of variables in play.
Currently, the Chengdu Panda Base has successfully bred two litters of three cubs in 2019. As of November 2018, the Chengdu Panda Base has bred 188 litters of 284 panda cubs, of which 195 have survived, equating to a survival rate of 98%.
