in all reality you can do without milk altogether.
the only concern that i have about raw milk is the fat content.
we must remember; cows milk is made for an infant cow which typically gains 80 lbs in its first year. so when you drink cows milk, especially raw, you are technically getting liquid meant to support an 80 lb growth rate.
i dont know exactly how much a baby cow drinks, so that could be a big factor too; if you are using milk in cereal and cooking, its probably not a big deal. but if you drink a lot of milk, its not a good thing to have all that fat. research is starting to show that the proteins in animal products and meat actually turn to acid in your body and eat away at your bones, instead of making them stronger. (this explains why despite increased milk use there is still increasing osteoperosis and other misc calcium deficiencies).
so whatever you decide, be careful, and i would skim as much of the fat off the milk as you can! :)
good luck!@
