I mostly agree.
I also miss some deer species like Chital, Père David's deer, Reeves's muntjac, Persian fallow deer, Sambar deer, Water deer, European roe deer, White-tailed deer, Kuhl's hog deer, Southern pudu deer, Japanese sika deer,
Cherotains: Javan chevrotain
From antiliope for africa I would like to see a great kudu its unique African antilope and a blebok which is a really pretty one also the yellow backe duiker. But yes asian species more needed like goitered gazelles, blackbucks, mongolian gazelles, arabian oryx etc..
From suids I only miss Visayan warty pig and the pygmy hog. But a Bornean bearded pig also would be nice. But yeah the developers mostly summorized the most needed ones.
From Bovids: we are not done yet: Gaur, Banteng, Lowland anoa, African forest buffalo, Yak but a Heck's cattle would be nice.
From camelids I still wanna see an alpaca or a vicuna.
From Equus I miss a Grévy's zebra and a Turkmenian kulan.
From tapirs: Althought I love mountain tapirs I would only go with the South-American tapir since it's the most common one in zoos.
From rhinos. The sumatran rhino.
For giraffids: There are 4 giraffe species since 2016 + the okapi-I wana see Rothschild's giraffe its one of the most common giraffe in European zoos, also the Massai giraffe because of the unique colour pattern.
From Caprini : Bharal or blue sheep, Barbary sheep, Alpine chamois, Markhor, Nubian ibex, Himalayan thar, Mountain goat, Japanese serrow, Muskox, Tibetian antilope, European mouflon, Snow sheep We still miss many
But from Hoof animals I mostly miss the domesticated one: goat petting zoos are really common in zoos, also they show and preserve national, or anciantbeeds.
Also there are some unique looking domesticated hoofed breeds like Scottish highlands cattle, Watusi, Hungarian grey cattle, Valais black nose sheep, Hortobágy racka sheep, Cameroon Dwarf sheep, Jakob sheep, Blonde mangalista pig, Wessex Saddleback pig, Minnesota minipig, Vietnamese pot-bellied pig, Albanian donkey, Poitou donkey, Fjord horse, Hucul horse, Shire horse, Andalusian horse, Falabella horse, Shetland pony.
Also there are breeding back project for aurochs and tarpan so Heck's cattle or the Taurus project cattle would also be nice addition and from the breeding back tapran project the konik or the Heck horse also.
