no
Not much if any in regards to the north American Pronghorn. I live in Pronghorn country and the fastest I have seen are in full flight response at around 70mph. So they would be close. I don't think a Cheetah would have any chance of catching a healthy one.
Pronghorn
Much faster. The pronghorn can hit 50 mph, while leopards top out at around 30 or so.
The adult Pronghorn Antelope's weight varies from the male to the female, the the female slightly lighter than the male. The male weighs from about 40 to 60 kg and the females weigh around 40 to 50 kg.
no im pretty sure a cheetah is faster
The Pronghorn, is not really faster than the Cheetah though, but it can run about as fast as the Cheetah for extended periods of time, where as the Cheetah can only maintain its high speed for short periods of time.
A pronghorn is not a true antelope because it belongs to a different taxonomic family than true antelopes. Pronghorns are the only surviving members of the Antilocapridae family, while true antelopes belong to the Bovidae family. Additionally, pronghorns have distinctive branched horns, which differ from the unbranched horns of true antelopes.
Slightly smaller than a whitetail deer. Probably about 90-100 pounds for an average buck.
caracal
The iPad typically receives the highest reviews for a tablet computer. Keep in mind, however, that software for an iPad is more limited than the various Android-based tablets that also get good reviews. You may want to consider an Android tablet from Samsung.
On land the fastest is the cheetah closely followed by the pronghorn antelope. In the air the fastest is the peregrine falcon. In the water the fastest is the sailfish.(similar to a swordfish).
Perhaps you should investigate a little further. Antelope, or at least an animal that is CALLED an antelope, run wild in several states. Perhaps you could research "Antelope Island" or Antelope huntng season in several of the western states. I've actually seen several large herds of Antelope in the western states, Idaho and Utah to be specific. But perhaps you know more than everyone else. (The person who wrote this answer needs to get off his/her high-horse. Oh excuse me, his/her high antelope, since this individual frequently studies them galloping on the majestic plains. Seriously, go jump in a lake) To actually answer your question, the antelope referred to in 'Home on the Range' is a pronghorn antelope...which actually isn't a real antelope at all (sort of like how peanuts aren't really nuts...their legumes). The pronghorn is from the family Antilocapridae, while true antelopes are from the family Bovidae. There are no true antelopes native to North America.
