Making Pieron's cat food- weight after grinding question
I'm making cat food using Dr. Pierson's recipe. I've done it a couple times before but this time I forgot to weigh all of the chicken thighs before I baked (20 min) and ground them up.
I know that I bought about 50-60 lbs of thighs but after baking and grinding them, the mix weighs 36 lbs. I'm surprised it only weighs that much. Is this kind of reduction normal?
I'm trying to figure out how much chicken liver, vitamins, etc I should add and don't know if I should base it on this new after baking/grinding weight or the approximate weight of thighs I bought.
Any help would be greatly appreciated!
