 There have since been intensive efforts at breeding the cattle, involving both in vitro fertilisation and cloning, and there is an ongoing program to perpetuate the breed in captivity.Nine cattle (the exact breed remains obscure) were introduced to Enderby Island, the northernmost of the subantarctic Auckland Islands group, in the 1890s when an attempt was made to establish farming on the island.The attempt failed because of the climate, with the island being abandoned in 1910 and the cattle left behind.
