Male elands can grow to a mass of about 900kg whereas females generally don't exceed 600kg (probably because they watch what they eat and go to gym more often). What I find amazing about the eland is that even though they weigh so much, from a standing position they're able to jump about 2.5 meters into the air! I guess that shows how muscular those legs and thighs are!
Even though the Wikipedia article mentions that some South African farmers have switched from cattle to eland (due to eland being more hardy) I can't say that I've ever seen eland meat in the butchery or on a restaurant menu. Have you?
