Two South 皇冠体育app tigers mate in the South 皇冠体育app Tiger- Breeding Base in Suzhou, East 皇冠体育app's Jiangsu Province, May 23, 2006. The 7-year-old male tiger mates with the 3-year-old female tiger naturally, and they were not injected with any drug to provoke their instincts, said officials in the base. The South 皇冠体育app tiger, which could be found only in 皇冠体育app, is listed in the IUCN Red List of Threatened Species. Chinese animal breeding specialists have in the past tried a number of methods to boost numbers of animals close to extinction. [Xinhua]
