Mei Xiang was put under general anesthesia and inseminated with a combination of fresh semen and frozen semen collected from the zoo's male giant panda Tian Tian. The scientists said they planned a second insemination later on Saturday.
Veterinarians detected a rise in hormone levels on Tuesday, indicating Mei Xiang was ready to breed but said "no competent breeding" between the panda pair had occurred.
