I don't think this recipe is going to work.
Ground turkey is okay if that is ground white meat.
If dark meat or fat are added, I would not use it.
Too much liver can cause vitamin A toxicity.
Most canned peas have an excessive amount of salt in them.
I don't see any oil here, so where would the needed linoleic come from?
Supplementation is not an option with homecooking. It is a requirement.
Calcium has to be supplemented along with a whole lot of other things.
The calcium/phosphorus ratio has to be figured.
Over the counter pet vitamins like Pet Tabs can't be used alone in homecooking to meet all vitamin and mineral needs.
I would talk to a nutritionist or find a recipe from one who is trusted.
The spaghetti is fine if you aren't worried about wheat allergies.
