The breeder required..... is this a puppy?
And I am trying to help you.
You have ounces of everything she needs? I did too, until I did the actual spreadsheet based on NRC requirements. And research into how much bone was actually in what I was feeding. For instance, a neck is 50% bone. Which means if you feed 10 oz, then you only need 2 oz of neck per the 80/10/10 but by the spreadsheet based on actual values of the piece thru testing, I needed 3 oz. Less than 10% of organ meat because the liver took the vitamin A way over the requirement which, since that is a fat soluble vitamin, could be bad. I found that the diet was completely void of iodine, low in potassium, manganese, selenium, choline, vitamin D and zinc.
If you are comfortable with what you are doing then please disregard all I've said. I won't be offended.
As Apex1 said, you can grind the bone if you are concerned with her harming herself. If I were going to add a supplement for calcium, it would not be from vegetation. It would be from bone meal which would be the complete bone with all the minerals and vitamins with it.
