calcium or MCHA

I have Alnutrin for meat & bone it has no calcium in it & I am going to grind a batch of meat and am woundering how much calcium or MCHA to use per pound of meat with the Alnutrin. Also would it be better to use MCHA, eggshell calcium, or calcium tartate ?

Any help is appreciated.

I could probably make an educated guess but the best thing to do is email Marta at knowwhatyoufeed.com (the manufacturer of Alnutrin) and ask her. Marta answers all their support questions and has a very good reputation for being helpful. There is a version of their product that includes a calcium source so she probably can tell you how much to add.
