none of the vitamins in milk are particularly sensitive to heat, with the possible exception of vit A, and it isnt possible to "kill" individual atoms of minerals, unless you plan to induce nuclear fission of said atoms.
Vitamin C is almost completely absent in pasteurized milk vs. Raw
Enzymes of any sort are almost completely lost in pasteurization. phosphatase, amylase, lactase, and Lactoperoxidase which help us absorb the calcium, break down the sugars, fats, and protein, and lactoperoxidase has microbial properties which help against pathogens.
~50% more vitamin E in raw milk.
Any beneficial bacteria is killed in pasteurization. Our own bodies are very efficient in killing off e.coli, rotavirus, and salmonella on it's own if we have enough beneficial intestinal flora. Almost all of the bacterial problems we see in milk now are stemming from horrible cow diets and horrible mass production practices.
A lot of vitamins are sensitive to heat in pasteurization IIRC, this is why our milk is fortified with synthetic vitamins.
Would raw milk be safe under mass production? Probably not.
Is it safe under local farm good practices? Yes.
