then you should go and feed them
We aren't allowed to have raw milk, it has to be pasteurized but doing so destroys some of the good qualities of milk.
So to get around that law people buy "part" of a cow.
If you own the cow then you can drink the cows milk without further processing.
However some say there aren't enough real benefits of it being raw. And then there can be bacteria also.
I'll just take regular milk, it's good enough for me.
