Todd, maybe this site gives some answers?

Apparently it's the high amount of beta-lactoglobulin present in cows milk
that's the problem for humans. There is considerably less of this protein in
human milk. Whether the proteins actually differ in mollecular composition
(is bovine beta-lactoglobulin identical to human beta-lactoglobulin?) I
don't know. I couldn't find a yea or nay on this. Perhaps it is simply the
ratio of this-protein-to-that that is unique to ecah species.
