JINAN, Jan. 11 (Xinhua) -- A long-maned goat sent by Taiwan as a gift to the Chinese mainland gave birth to a lamb on Wednesday in a national park in east China's Shandong Province.

The lamb was born at 12:48 a.m. to its mother "Leyangyang" ("happy goat" in Chinese), who arrived with her partner "Xiyangyang" ("merry goat") and a pair of deer at the Liugongdao National Forest Park in the city of Weihai in April last year.

The lamb successfully stood up on its own one hour after being delivered, indicating that it is healthy. However, the lamb will still require a full health checkup within three days, according to zoologists from Taiwan.

The lamb will be named Tian Tian ("sweetie") if it is male or Mei Mei ("beauty") if female, sources with the national park said.

Long-maned goats are endangered species and are indigenous to Taiwan.

In October last year, the female deer gave birth to a fawn in the park.

The goats and deer were sent as gift to the mainland after a pair of giant pandas, "Tuan Tuan" and "Yuan Yuan" (together meaning "reunion"), were flown to Taiwan in Dec. 2008 to boost cross-strait exchanges and cooperation.
