Husky_Mom, are you talking about Satin Balls? They're used primarily to put weight on underweight dogs or entice picky dogs to eat. I don't think one should use it extensively or as a main component of a meal, but they are good supplements, especially is gaining weight is one of your main priorities. Recipe:

I know I'm going against a lot of raw feeder "rules", but Finn could honestly use a bit of carb. Sure, protein is good for the long run and for building muscles, but it's carbs that give him quick energy boosts. Evo is unique in the sense that it doesn't use grains. However, it uses potato, which is, of course, starch (aka - carbs). If you'd like to continue feeding raw, how about adding some pasta/macaroni/brown rice/potatos/etc.?

Also, I saved the recipe for a typical meal of a racing Greyhound kennel. If you'd like to see its components, just PM me It's geared towards feeding a large number of dogs (approx. 70) but you can see what types of "ingredients" they use.
