HARBIN, Dec. 28 -- A total of 105 Siberian tiger cubs, one of the world's most endangered animals, were born in 2014 at a tiger park in northeast China's Heilongjiang Province, the park said Sunday.

Over the past decade, the Siberian Tiger Park, the largest Siberian tiger breeding and field training center in the world, has adopted planned breeding of tigers in a move to protect strong genes among the species' population.

"The number of artificially bred Siberian tigers in the park is not 'the more the better'," said Liu Dan, chief engineer of the park, "we have been strictly controlling their population to ensure the quality of the species."

Currently, there are more than 1,000 Siberian tigers at the park. All the tigers have undergone DNA tests to prevent "intermarriage" among them and wildness training has made them more efficient predators, Liu said.

Siberian tigers are among the world's 10 most endangered species and mostly live in northeast China and eastern Russia.

China established the Siberian Tiger Park in 1986 with only eight Siberian tigers.
