世界最小的大熊猫幼仔在成都出生
A female giant panda cub weighing 42.8 grams, about the weight of an average chicken egg and the world's lightest ever, was born in Chengdu, capital of southwest China's Sichuan Province, local authorities said Thursday.
一只重42.8克的雌性大熊猫幼仔在成都大熊猫繁育研究基地出生，这只幼仔的重量与一枚鸡蛋相当，是世界上最轻的。
The cub and her twin sister were born to giant panda Chengda on Tuesday at the Chengdu Research Base of Giant Panda Breeding.
The cub's birth weight was less than one-fourth that of her sister which weighed 171.9 grams, and it measured only two-thirds as long as her sister, according to the base.
The base said the cub is now in stable condition, thanks to round-the-clock care from researchers at the base.
Before the cub's birth, the world's lightest panda cub was Wuyi, weighing 51 grams when he was born in 2006 at the Chengdu research base. Wuyi now weighs 132 kg.
