 The Cincinnati Zoo acquired two female white tigers from the Nandankanan Zoo, in the hopes of establishing a line of pure-Bengal white tigers in America, but they never got a male, and didn't receive authorization from the Association of Zoos and Aquariums (AZA)'s Species Survival Plan (SSP) to breed them.The Zoo Outreach Organisation used to publish studbooks for white tigers, which were compiled by A.K.Roychoudhury of the Bose Institute in Calcutta, and subsidized by the Humane Society of India.
