Guess who!?!?

I love black and white animals
who always shout out moo
their milk makes you strong and healthy too

You can find them on a farm eating grass or taking a nap
they will be on the country side, you might want to use a map

If you haven't guessed the animal that I'm TRYING to tell you,
well then, here's another clue! The animal I am thinking of starts with a c and ends with an s (if its a plural) have you guessed it? .. well its a COW... ohh yes!

I love cows.
