China Giant Panda Protection Research Center has cultivated ＂national treasure＂ among ＂national treasures＂.

　　The giant panda is a national treasure, and the male panda with natural mating ability is a national treasure. At present, the number of male giant pandas with natural mating ability is very rare in captivity, accounting for less than 5% of the population. On the morning of February 29th, 2016, the 7-year-old male giant panda "An ‘an" belonging to China Giant Panda Conservation and Research Center successfully mated naturally for the first time in Ya ‘an Breeding Base, which indicated that another male animal with natural mating ability was added to the captive population of giant pandas.

　　An An was born at 7:29 on August 6th, 2008 in Ya ‘an Base of China Research Center for the Protection of Giant Panda. His father is Ling Ling and his mother is Cao Cao. Because of its high genetic value and male, the staff have great hope for its reproduction from birth, and at the same time give it special feeding and training. In 2014, "An ‘an" was sexually mature, and the giant panda breeding staff of China Conservation Giant Panda Research Center began to let it participate in the breeding plan and create opportunities to train its natural mating ability. Since 2014, "An ‘an" has been caged with 13 female giant pandas at the peak of estrus. With the increase of caging times, "An ‘an" has become more and more dominant and interested in the opposite sex. On February 27th this year, the staff arranged "An An" to the "Huamei" neighborhood of the female giant panda in estrus peak as planned, and "An An" began to show weak mating desire. After four long times of cage-closing, "An ‘an" finally began to erect his penis on the morning of February 29th and showed a desire to mate, and then successfully mated with the giant panda Huamei twice.

　　"An ‘an" has high genetic value in captive population and has natural mating ability, which will play a very positive role in improving the genetic structure and increasing the genetic diversity of captive giant panda population.
