Must admit to having had a leisurely forenoon at the 'alchemy' room, with a decent though hardly exceptional hill doe I took last week. For some time I've been curious to quantify the yield v waste. The total of waste is shown:

Most of this I'm sure would be welcomed by my lab, but he's still a bit young, so it'll go out. head, skin, forelegs, all edible offal and scraps find a use/value; I dare say I could watch over the small green and lungs left ( I did have a lady who took these dried for her dogs until recently) and hope for a chance at Reynard, but this passed.
Most of the rest, save some bones unseen here, and 3 1/2lb mince scraps waiting to go through the mincer, which i'll do at the same time with another one I've got to do later this week:

Part of the 'recycling team', lovely rich yolks, folks!
Still, excluding the remainder of the gralloch, the waste here was 270g from a 15kg roe doe, so a little under 2%; waste not, want not!
