Cows produce milk that is easy to digest.  It’s a great source of protein, and is well-nourished by grass-fed cows.  We can drink it raw, or you can easily make cheeses and butter from it.  Chocolate is also made from the cocoa beans which grow on a type of tree that a lot of cows eat.  So, the answer to your question is, there are all sorts of good reasons to drink cows milk.

Why not horses milk?
user
Horse’s milk is not easy to digest and contains a lot of fat.  If you drink it, you get diarrhea.  Also, there are not a lot of horses around for people to milk.

It does!?

Sorry, there are not a lot of cows around.  If you’d rather drink horses’ milk, I’d suggest you visit a petting zoo and take a peek!

Now you are teasing me!
