A pair of extremely rare white Bengal tigers, obtained from a Canadian zoo by the Saigon Zoo and Botanical Garden in downtown Ho Chi Minh City, have given birth to 3 white cubs.
The three cubs, about one month old, weigh from 3.6-4.1 kg (8-9 lb), the zoo management said in its first statement about the cubs.
The smallest newborn cub has been raised separately and has become the heaviest among the trio, zookeepers said.
The two tigers were obtained from the Elmvale Zoo in Ontario in 2009, when they were about two years old and the zoo management named them in Vietnamese as Lem and Luoc.
Last year, an Indochinese tigress gave birth to five cubs at the Saigon zoo, a rare case as a tigress normally gives birth to 2 or 3 cubs.
In 2012, a white tigress at the Trai Bo Tourist Area in Nghe An Province delivered 2 cubs, also white, after a 114-day pregnancy.
Worldwide, there are about 2,300 white tiger, a pigmentation variant of the Bengal tiger, which are mainly found in captivity.
