Cows can't always get all the mineral they need from licking a block. It's best to leave free choice loose mineral out for them.Christiaan said:My silly beasts don't roll in the ashes, they just stick their noses into the hot ashes and lick it up. Nigel has even blistered his nose!!! I don't think they do it primarily for the minerals since they have a well licked mineral block. I think they like the hot sensation! Too weird for me to understand.
