When I was in Namibia, most game animal carcasses belonged to the landowner. They marketed them in the capitol, Windhoek. The native trackers, driver, etc. would remove the guts, strip out the nasty stuff and hang pieces on the smooth (non-barbed) wire fences to dry in the sun. They would eat it the next day along with 'mealies' (yellow grits).
It looked very unappetizing. Biltong was almost exclusively for the wealthier people. It was highly prized by them.
After butchering a zebra, I saw the skinners cut all of the meat into strips for biltong. I said, "That will make some good eating." The PH said, "They won't eat zebra. That's for their dogs." They had a taboo of some sort to eating zebra.
