I think for 3, 4 or 5 years.
I assume that by "sable antelope" you mean "sable antelope", as I have never heard of a stable antelope. A sable antelope is a species of antelope with a black or brown pelt. both genders have long, curved horns, and they have distinctive manes, earning them the nickname "horse antelope." Sable antelope live in savannas. but, if you are not referring to sable antelope and mean something different by stable antelope, then I'm sorry I couldn't help.
