National Zoo panda inseminated

WASHINGTON (AP) - An expert from China and scientists at the National Zoo are hoping their second attempt to artificially inseminate the zoo's female giant panda Mei Xiang is a success.

Zoo officials say the procedure was conducted Sunday night after scientists determined the zoo's panda couple had not mated naturally.

Dr. Li Desheng from the China Conservation and Research Center for the Giant Panda will performed another artificial insemination Monday evening with the zoo's scientists.

The zoo says Mei Xiang was inseminated with thawed semen from male panda Tian Tian that was collected in 2005. Staff will continue to monitor 13-year-old Mei Xiang's hormone levels and conduct ultrasounds in the coming months to determine whether she is pregnant.

The panda couple has produced one cub, Tai Shan. He was born in 2005.
