“We had a very busy weekend at the Zoo Atlanta panda building. Lun Lun ovulated (finally), most likely late Saturday night or early Sunday morning. So, starting Sunday morning we did introductions between Lun Lun and Yang Yang to give them an opportunity to mate naturally. Since they did not mate, Zoo Atlanta’s veterinarian team, keepers, and curators, a Chinese colleague, and two American colleagues from other institutions stepped in to perform artificial insemination on Lun Lun. We were able to collect enough fresh semen from Yang Yang to perform two separate AI’s on Lun Lun. Now, we sit and wait to see if all our efforts will once again produce a cub.” Kate Roca, Carnivore Keeper III
