Feed the hay to the cows. Watch them. Make sure they have sufficient hay that they can reject that which they do not want. After a while you will find they reject very little.
An easy way to tell is to feed them normally. Then within a hour after your last feeding put out some ofthe hay with the mold. Watch to see what portions they reject.
Personally I would simply feed it, and not worry.
