Regarding antelope importation I am going to believe it when I see it. One would believe with our climate and huge open range zoos many antelope species would thrive,at the end of the day it comes down to the guys running the show, if they would rather spend the money on hotel’s then thats the way it goes. As we have seen with the resent importation of zebra it took two small regional family zoos to do the largest importation of zebra into Australia. This would have been pocket money for any of our major zoos but they would rather have badly inbred animals it would seem.
@Swanson02 likely hit the nail on the head by mentioning zoo’s are quick to prioritise imports for the high profile species, while allowing the low key species to inbreed for generations.
The general public know our elephants and great apes by name and would wax lyrical about incest on social media if they were bred with close relatives. However, nobody can identify any communal herd living Bovid from its herd mates; let alone learn its name or recite it’s genealogy.
