I'm trying to put together a spreadsheet of calorie counts for my raw food mixes. Calories per ounce are easy to find for meat and organs, but I can't find anything for bone. Maybe it's never been studied because we humans don't sit down and munch on a big pile of bones, like our pets are able to do.
Anyway, chicken bones are 10% of all my mixes. The exterior, hard "boney" part of bone is mainly calcium carbonate and collagen so it probably doesn't have many calories. However, red bone marrow is primarily red blood cells and fat and may be fairly calorie dense.
Also I've noticed that almost all chicken bones contain red bone marrow (versus beef marrow bones which are predominantly fatty yellow marrow). My guess is that red marrow is slightly lower in calories than yellow marrow.
Taking a shot in the dark that someone here has done the research and actually found an answer. I'm coming up with nothing.
