They aren’t horns like the various antelope in Africa have. Antlers are shed and then regrown every year; they have a blood supply to the core and to the velvet skin.
In antelope (sable, impala, kudu, etc.), a broken or lost horn is permanent. Horns are hollow and made of keratin, same as rhino horns and human fingernails.
I live in a Northern Michigan forest. I hunt a lot. I know what an antler is from both whitetail deer and elk. They are dry with ZERO blood contained in them. An antler is actually hair, just like our finger nails and just like the deer’s hooves and antlers. I have a resident herd of whitetail on my land (approx 25-30) and elk winter on my land on top of my hill.
