I've found that the way animal weights is expressed in different parts of the world varies somewhat.I would have thought more. But it is about double what our big Kudu weighs ; very impressive. Our biggest is
the Eland that weigh about 800 - 2000 lb. Very nice eating too.
In the U.S., we mostly talk about the weight of a live animal as if it were a cow walking across the scales at a livestock auction -- that is, before field dressing. Other places I've found that when people talk about the weight of a deer, sheep, or antelope they mean with the entrails below the diaphragm removed. Still others speak in terms of the hanging weight of a skinned carcass. Even then, some count the weight with head and lower legs on, while others count the weight with those parts removed.
So, we're not always apples-to-apples on weights, which can often be confusing (and sometimes even cause ill feelings).
