My son's market steer is really frustrating me with his lack of eating. It hit me last night that he must be lacking some time of mineral because he loves to walk up to me while I am in his pen and lick my shoes and coveralls. He literally tries to put my shoes in his mouth. I have white salt blocks and mineral blocks in his pen. Any thoughts on what he might be lacking in his diet? If I can figure it out and add it to the feed, he should devour it like my shoes. ;D
