Hoofstock are my All time favorite animal group for as long as i could remember, its really hard to choose which group of hoofstock, If i had to choose i will just say my 3 favorite species in order would be
1. Thomsons gazelle ( Eudorcas thomsonii)
2. Grants gazelle ( Nanger granti)
3. Nubian ibex ( Capra nubiana)
Although these days i have really been finding an interest in caprids, suidae and bovinae because they are very overlooked and when the average person (non-zoochatter) thinks about a goat, sheep, pig or cattle they think of the ones on farms and do not realize that there are wild species like Siberian ibex, Dalls sheep, Bornean bearded pig, Gaur etc.
Hoofstock are really in danger because they are not popular like animals such as Elephants, Chimps, Lions etc, and because of that if a zoo were to choose between a tiger or goral, they would choose a tiger
My best memories in zoos as a kid were in horn and hoof mesa at san diego zoo seeing the vast ungulate diversity that the zoo had back in the day, another great memory in zoos as a kid was riding the Wgasa bushline at the san diego wild animal park and seeing their vast ungulate diversity.
