Red clover

So I've been reading a lot about red clover hay... It seems like there are a lot of very different opinions on it. I have a lot in my field mixed with what I believe is Orchard grass (grows in clumps) some people say it's high in protein and other minerals. The salvation issues is due to a fungus that could potentially grow on the clover not the clover itself. Any ways.... My horses love clover so it'll work for us. Any other opinions on it? I mean it's a legume same as alfalfa... Higher protein and minerals that straight grass hay. How bad could it be?
