I’m not good at guessing bone content on something that is meat and bone. HDM once told me to give the meaty bone plus half again its weight in boneless meat. So, if your pork rib with meat on it is 2 oz, it would be enough calcium for another ounce of meat, but ribs have more bone than, say, a chicken thigh, so… It’s supposed to be 10-15% bone in the diet, I think you would have to be the one to eyeball that.
