Current- ly, the two adults and the cub are in good state of health, and especially the cub is healthily growing according to its weight and other health indicators. This is the first birth and survival of cub of Malayan pangolins in captivity. It proves that Malayan pangolin can successfully breed in appropriate captivity conditions and the reproductive parameters of Malayan pangolin are also determined, which provide valuable reference for other species of pangolins in artificial breeding, and also give effective way for population growth, ecological restoration and species conservation for pangolin in the wild.展开更多
