Located in northeast China's Heilongjiang province, the park has over 1,000 Siberian tigers. Scientists handpick certain tigers, using a DNA database, to breed the next generation every year, the park announced yesterday.
Park's chief engineer Liu Dan said the park has been controlling the tigers' population to around 1,000 in order to maintain the ecological balance.
The peak season for the breeding of Siberian tigers is in May and June. The cubs, after living with their mothers for some 100 days, would be sent to a semi-wild environment of the park so that they can learn to run and hunt, state-run Xinhua news agency reported.
