Huang Yan and Zhou Yingmin, experts from Sichuan's Wolong Panda Breeding Center, have arrived in Taiwan at the night of February 6th, providing guidance for the breeding of pandas Tuan Tuan and Yuan Yuan, which were given as a present from Mainland China. Tuan Tuan and Yuan Yuan, which have already settled down in the Taibei (Taipei) Municipal Zoo, have already reached sexual maturity. Zhou Yingmin is a specialist of human-induced panda breeding. This time he will stay in Taiwan for at least one month, as the human-induced impregnation of Tuan Tuan and Yuan Yuan is imperative.
Zhao Mingjie, spokesman of the Taibei Municipal Zoo, announced that at present Tuan Tuan weighs 129Kg, while Yuan Yuan weighs 118Kg. After arriving in Taiwan, Tuan Tuan has not only gained more than 10Kg, but his testicles have also become gradually larger. Convener of the pandas breeding plan in the Taibei Municipal Zoo, said that the panda breeding season is between February and May every year, the heat period (estrus) lasts only two weeks and there are only 2-3 copulation days. It is reported that natural mating between Tuan Tuan and Yuan Yuan is preferable, though an artificial insemination plan has also been presented already to relevant personnel. Personnel in charge of the work in the Taiwanese zoo perform an ordinary manure and urine tests on Tuan Tuan and Yuan Yuan, as well as organize the routine daily drill.
Taibei Municipal Zoo has fixed a date for conducting an abdomen ultrasound examination for Yuan Yuan, preparing for the inspections in her future pregnancy time. The zoo aims to formulate a training plan for a testicle massage for Tuan Tuan, which, except for stimulating the testicles' development, is hoped to be a natural way to collect his seminal fluid in the future.
