Some around here do raise buffalo ... not beef-a-low a cross between buffalo and cattle.
The fences are made of welded pipe and keep the buffalo contained.
I've had them walk right alongside my pickup in Yellowstone National Park and in Custer Nation Park, When in Teddy Roosevelt National Park .. several were blocking the roadway as they tend to do and a big bull took a liking to the rear tire on my pickup and spent several minutes licking it ......... also left snot on the side of the pickup box.
Growing up on a farm and raising Herford cows, I'm well aware of the strength of a cow and a Herford bull is even stronger ... can snap a rope like it was a piece of string. A buffalo is far stronger....and some call them "fluffy cows!" LOL LOL Not hardly.
