Why does cow milk trigger my allergies and goat milk does not?

I have never thought much more or less this, but it seems that cow milk make me feel sickly, while goat milk (cheeses) in truth seems to see me. Any ideas?Why does cow milk trigger my allergies and goat milk does not?
they may own different proteins, and in a true allergy, its protein i.e. the trigger. If you are truly allergic rather than lactose intolerant (in otherwords, if you swell, itch, enjoy trouble breathing, rather than purely indigestion) than you may only be allergic to cow's milk protein, and thus would be fine near goat's milk or sheep's milk etc.
lactose
Drink goat milk
alot of times, the allergy is from the form of processed milk you consume. Try Organic milk. My mother in canon can only drink Organic milk minus any allergic reactions. I myself enjoy noticed that my system is alot better on the Organic Milks.
